Oil Coolers Explained

Rocket Rod answers your questions about Oil Coolers and Transmission Temperatures as Jeromee stacks and packs product ready to meet the ever growing demand. Do you need an oil cooler? Can you run a transmission too cold? Just how Hot is too Hot? This is one episode not to be missed!!

[@wailingalen]

Nice to see homegrown operations doing well. Wish you well, and greetings from FL, US! 😇

[@WholesaleAutomatics]

Thanks!

[@davidbland1859]

I have recently installed one of your coolers to my BT50. I immediately noticed a substantial drop in temperature and the box seemed to perform better especially towing a 2.5 t van. I run a automotive mechanical workshop in the eastern suburbs of Perth and have started recommending auto coolers from Wholesale Automatics to my customers. Great gear!!!

[@WholesaleAutomatics]

Thanks David! means a lot to have other mechanical workshops giving positive feedback on our products and excited you are one of them.

[@JamesWilson-ox1kc]

Which shop is that david

[@AmirSharon]

Thanks a lot. After a gearbox failure in my Forester Sport 2021 i installed oil cooler with derale fluid control thermostat. shuold i drop it?

[@mohammed61750]

As a mechanic been working for 18 year in the field, it’s one of the best upgrades you can do for any car .

[@rosshalliwell2096]

great vid Rocket ,I had one installed up here in QLD two weeks ago on my 4lt V6 auto Hilux best move I've done for towing our camper trailer around Australia transmission is cool as now , thanks again for your help with solving and stopping a problem somewhere up the long winding road ahead

[@stealth5959]

Very impressive inventory and stock organising. I don't have a auto in 75 series but I love the videos. 😊😊😊

[@JohnRolyAU]

I'm 13 years into my 200 with 180K on it. Mechanical sympathy is the #1 tool. being aware of EGT and trans temp are part of towing and knowing what you're doing. I have had nomad and lockup for years, also get trans serviced at Wholesale as needed, trans fluid has always been good. Also noticed with the Safari Armax ECU with crazy KW and Torque, the lockup stays in a lot longer without manually having to engage it.

[@Mikadelosangeles]

Very informative. Great video

[@user-bl4rf3pb8b]

I have a case 1150 dozer and have had it cook the oil several times running regularly up to 130 degrees. Put an auxiliary air cooler in front of radiator to augment the oil cooling tubes running through bottom tank of radiator. Now runs better. Great site you guys run. Thanks

[@spudboy1328]

Thanks for addressing the 'how cool is too cold' topic. I've fitted a trans cooler to my 150 Prado 3.0L, which was commonly running temps of 105 to 107 up hills, just heavily loaded (i.e.not towing). Now I've dropped at least 20 degrees off the top end, but for locked up highway driving the temps were sitting much lower than before at around 55 degrees. I was worried 55 was 'too cold' but seems there's nothing to worry about, so thanks for going into that. Cheers - David

[@TheCheckit96]

Are the temperatures engine coolant temp.

[@ashwynfernandes]

Do you find the shifts have now become crisper/harsher during the colder months?

[@andrewiannello6548]

Excellent explanation 👌. Explained why my Pajero Sport likes higher revs on long uphill towing. It will still pull in manual lower gear, however on auto it prefers a higher gear, obviously it's tracking transmission temperature. After throwing codes in manual once before, I tend to leave it in auto now.

[@murraypeate7914]

I had the Ranger Ultimate bundle deal installed on my 2020 Ranger a month ago. ScanGauge 2 was regularly reading ATF temp around 102 to 105 degrees. Now with the twin heavy duty cooler, bypass value and deep cast sump the temp is down around 70 to 73 degrees.

[@WholesaleAutomatics]

Great to hear Murray

[@stephenashley3546]

I've got my 'Ranger Bob' booked for late June to get the same kit. Nice to hear another success story.

[@Sabumnim666]

Hi Murray I have a 2021 wildtrak with the 10 speed and my van is usually at about 2800kg up or down by 150kg I use an ultra gauge which reads in Fahrenheit so I sit at 90km or just aver when towing and the temp has never made it to 185F even when towing in 38C. I towed through the Adelaide hills on the express way it was cool but again never exceeded 180F. Is your the 6 speed? Pretty curious about the differences.

[@79series]

Can you get the 2 readings of "pan temp" and "torque converter temp" on the scangauge for 2013 rangers like you can 2018 hiluxs with scangauges? Or do rangers only have 1 box temp sensor @WholesaleAutomatics

[@bradmccausland9242]

I fitted one to my LDV T60 it made great difference and no more overheating I would recommend this product

[@dark-grey1241]

You mentioned Scan Gauge and that you prefer temperature gauges. I forked out the extra dollars for a Scan Gauge III for the best of both worlds: gauges (9 instant glance gauges on 3 screens selectable by one press of the screen) and the ability to check/clear fault codes, simple OBDII one electrical cable connection, etc. SCIII has two coolant temp readings in my Ranger that can differ a few degrees to each other. Scan Gauge III measures in 1 degree increments for temps. It also allows me to see the tyre pressure gauge readings I didn’t even know were fitted to the car. I bought a 2nd hand 2016 Ranger and a relatively heavy van in close succession. The Ranger was not fitted with a trans cooler when we towed the van home, but I had one fitted not long after that first trip, and the transmission fluid replaced at the same time.The first trip in pouring rain and ambient temps in the high 20s saw the transmission temp up to 110 on the hills. With the cooler fitted and fresh fluid I’m consistently at 90 and under. Now I’m watching the trans temp less, but still like a hawk, and the coolant temps more which respond well to driving slower up big hills, only when necessary. I’m not a fan of holding others up just because I’m towing.

[@ChrisSmith_bike]

I agree with your comments 100%. I have a 5 year old D-Max which has had a transmission cooler from new. I fitted it because I have a trayback camper for serious outback travel with a travelling weight of 3.3 to 3.5 tonnes. Temps are normally in the range 50 to 60 and up to 75 in heavy sand. The D-Max in standard form runs oil lines through the radiator water for cooling. This makes possible water getting into your transmission. For Isuzu' engines you would have to be mad not to disconnect the original oil cooler lines and fit an external transmission oil cooler.

[@mrdoodle8748]

I don't tow so I have not seen the high temperatures mentioned in the video but buying a Scan Gauge was a great investment for me for my 200 series. A bit of faffing around to be able to get the data from the ECU, thanks to the Landcruiser forum for the instructions on how to do that. I would definitely consider fitting an oil cooler if I was seeing the trans temperatures getting anywhere near 100c

[@stevec1835]

Hi mate. I have a 2010 bt50 I fitted a cooler after rebuilding my auto that cost 4&a half K 😡. I've Just put a temp gauge on it & runs between 40 & the hottest it got is 66c going up the Toowoomba range. I've been wondering what it should run at so thank you so much for answering my question 👍. Keep up the awesome work champion.

Very good info, i have 2022 LSU dmax, travelled Perth to Brisbane along the south May last year, had engine guard fitted to observe temps, establish a trend. Picked up caravan in brisbane traveled Brisbane - Tennent creek - darwin back to perth , Obiously by now sept Oct temps picking up. No cooler fitted at this time. Soon after home in Perth , had a cooler fitted by Wangara Auto transmissions, noticable difference in Transmission Temps. As vidoe tells you ,have a temp gage, now use Scangage 3 .

Best up grade on my BT50 dropped my transmission temp by 25 degrees running up steep hills a must for all auto's CHEERS Rocket🍺🍺

[@danieloneill4356]

I fitted a Mishimoto 500x190x19mm ATF cooler to my Toyota U760E transmission. It's the largest cooler I could fit behind the open area of the grill (the squarer coolers would be "hidden" behind the front bumper and not in the air flow). Since fitting the cooler my ATF runs at about 65 deg C most of the time and the fluid isn't black after a few weeks of driving like it used to be. My car is 11 years old and it shifts and drives better than ever.

[@009914gb]

Well said Rocket 🚀

[@heathholland2319]

I fitted one to my 200 and it made a huge difference, puts extra oil in the system and keeps the oil much cooler. Goes well with the Nomad valve body too. Cheers guys.

[@crispyinasia61]

Do you have any issues with air obstruction to the radiator and hence increasing that temperature as well. My Trans temp is frequently at 120 degrees when driving in the soft beach sand, and so I tend to take a break before continuing. But it may be time to upgrade the cooling side.

[@jamesmedina2062]

@@crispyinasia61manufacturers want your car to fail in a period of time for sure. their dealer networks depend on it to stay alive. So better radiators are often a real need when in hot climates. Don't be a statistic!

[@daveb1635]

Thanks for all your videos. I fitted a HPD cooler on my 2015 DMax soon after I bought it. I was towing a 1.8 camper and the trans light came on. The place I bought the car from said I don’t need to put a cooler on. Yes they were wrong. Q: it’s it a good idea to fit a thermo fan in front of the cooler for slow speeds. Dave

[@WholesaleAutomatics]

No not at all Dave, The coolers make a massive difference by themself, and the engine fan is still pulling air over the coolers in any case.

Fitted your cooler to my 18 Colorado, leaving on Sunday for Darwin towing a 2.4t van, car has had a remap, bullbar, winch 9”driving lights, rocksliders, rear bar, canopy, rear drawer, 147ltr LR tank, 265/75/16 Wildpeak AT3W tyres, 3” ehhaust with a hotdog only. Its getting up there in weight . The cooler when not towing has the trans at mid 60c, it was around 80c pre trans service and cooler fitment . Will be interesting to see how it performs as the hottest i have had the trans oil was 117c coming up the Adelaide hills after the V8 Supercars in December last year towing the van.

[@jonbeecroft4912]

I've installed one of your coolers in my prado 120 i tow a van as well, we have done a few big trips before the cooler and after the install and it makes a huge difference with the cooler the power transfer is a lot smother and dose not seem to fade away id say its due to the oil staying cooler.

[@overlandready]

PX2 Ranger ultimate kit installed, so so pleased I have done so early in the vehicles life pre 55k. Only wish there was a lock up kit for the PX2.

We are on the lock-up kit now and will have it completed in a couple of months Brian.

[@bruceh1670]

Really enjoyed this video. I tried 4th gear instead of 5th on my PX1 ranger towing our 3.1 tonne van. Worked a treat. Lowered temps from 97° to 92.6° for a cost of 500rpm. This about normal around town temps for me. As you said rangers run warm! Having said that my wholesale trans cooler doesn’t help in stop/start city traffic sadly. Maybe a fan would help?

[@WholesaleAutomatics]

No room for a thermal fan and not the fix you should be looking for. What you really need is the thermal bypass valve installed as that will allow the coolers to work 100% of the time. The trouble is your current thermal valve is holding the oil temp at 90c + which is a complete pain. Fit the thermal valve and you will notice a huge difference. Here is the web link: automatictransmission.com.au/shop/thermal-cooler-bypass-valve-with-install-kit-to-suit-ranger-and-bt-50-6-speed-autos/

[@HealthSupercharger]

I agree with this man about lower gear helps the car climb better i live in Colombia where i put the car into 2nd gear to climb the slow 35 to 45kph windy roads. It stops from switching into 3 and 2 all the time

[@spencergordon2642]

Great vid 👍🏼 I installed a cooler on my 150 Prado 7 years ago. Temps on highway around 65c and around town 75c 👍🏼👍🏼

[@frankvarga1502]

Hey mate thanks for the vid. I am having your full kit fitted to my PX2 Ranger in two weeks next door to you guys as I left the booking way too late and you are all booked out anyway I done an 8 month trip of Tassie last year April to December towing our caravan all over the isle and the Ranger was working very very hard at times especially in the West I often wondered weather the transmission would hold up which it did without me knowing if it too indeed struggled. we are heading off to the Cape early August towing the caravan leaving it with friends in Cairns then off to do the Telegraph track and on return to Melbourne heading West to Darwin then down the middle and back home I would say this is the time the cooler will truly come very handy. You totally rebuilt my son Frank Jr's PX2 Silver Ranger not that long ago.Any extended away trips in the pipeline?

[@mustafasoylu9473]

Hi Rod great info, I fitted a PWR auto cooler to my 2010 Colorado when I first purchased it, definitely agree that it makes a difference.I tow a camper trailer and when not towing and 4x4ing it is the best insurance in my opinion, Ive bypassed the radiator as I have the larger cooler that was available.in addition I am looking at putting heat shield(designed for hoses) over the return line, if you can comment on this from your professional advise would greatly appreciate.

[@WholesaleAutomatics]

I would be reconnecting the radiator as one cooler is not enough for the Colorado. Reconnect so flow goes though radiator first then the new cooler second. You just need to install flexible conduit to all the new cooler lines.

I watched John's video then I watched this one. They both gave me a better insight into auto cooling. The one question I still have is weather you would recommend running the trans oil through both the radiator and the cooler. I have a HDJ100, 5 speed auto, and it runs a cooler and the radiator. Thanks for a very informative video. Cheers, Phil, NZ.

I had a different brand on my last Prado, decided to go with yours on the new one, and just ordered it today, Question; does the 2022 Prado 150 really need a lock-up kit? I had one on the last 2017 but that one (130kw) struggled a lot more than this one (150kw). I tow a 1500kg camper infrequently.

[@starwombat]

Thank you for a great and informative video. I have a 2020 3.2l Ranger and regularly run above 100 degrees. Your video prompts me to ask two questions. 1. How would the installation of an aftermarket product, like an oil cooler, affect vehicle warranty in the event of a transmission failure? This question would seem particularly relevant if an unlikely leak developed in a hose to the cooler or some other event that could be linked to an after-market installation. 2. Why do Ford engineers make these vehicles like this, which according to you will possibly make them more likely to early failure? I do understand if you do not answer this one.😊

[@WholesaleAutomatics]

Greg, we are yet to have ever seen a single case. They can't void your warranty as it's against consumer law, however if a problem is the direct result of our product, then I can't blame them for handballing you back to us and we are fully insured for such an occurrence. Luckily, after thousands of sales no problems so far. We have even had dealers call and order kits to help them with their own customers requirements. To answer your second question, If you use them as an everyday runabout they would be fine although would still last longer with an oil cooler installed simply due to making the seals last a lot longer but when adding bull bars, winches, off road tires, engine tunes, and the list goes on and on not even considering towing at this point. We do a lot with our vehicles in Australian that is considered largely uncommon in almost every other country, so when any manufacture is trying to build a vehicle for a widest possible worldwide market the Australians are certainly at the extreme end of the scale and I'm sure this makes their job far more difficult. Best answer I have I'm afraid Greg.

[@6226superhurricane]

coolant temp on nearly all modern vehicles around 90 degrees c so it's interesting to hear you recommend temps not go much over that, an engine coolant heat exchanger is going to have trans temp at 90c with no load and when the coolant temp cspikes to 100-120c (which is still fine if not boiling) on a hill so will the trans oil. i would've said oil temps over 140c are starting to become an issue.

[@WholesaleAutomatics]

No, not many run that high and even the new Next Gen Ranger has removed the thermal valve from factory to bring the temps down a little more now that they are running a lighter weight oil. Most models start to go into some sort of preservation mode at around 120c and most will also start to fault code at 125c. Only the older 4 speed autos used to be able to run at the hotter temps but not the newer 5 speed onwards models. I used to tell people to pull over at 140c until we started getting feedback that most don’t make it close to 140c without warning going off.

[@bobblyde282]

I fitted 2 tranny coolers to my 120 series prado, only change the oil in the tranny ever 150,000ks still pink & no burnt smell. I also put one on my power steering pump at the same time. Car has done over600,00ks & never had the pan off the tranny. Bob Blyde

[@Perth4WDandCamping]

G’day Rod. Great video. Interested in any thoughts or experiences on your new cooler on a Next Gen Ranger. Generally I find my transmission (v6 XLT) only runs on the hotter side idle at the lights, and towing my van in hilly terrain. Seen it get rather warm on the beach too (40 degree day) - however nothing over 100 degrees, even whilst towing. In your experience, will adding a cooler block or restrict any air flow into the radiator? Keep up the great vids 👌

[@WholesaleAutomatics]

Cooler is a must have for the new Next Gen rangers, Doesn't restrict flow as there was plenty of room to keep both coolers just on the one side.

[@WholesaleAutomatics]

To some extent both but mostly torque convertor as this is by far the most reliable, gives instant data and is the most destructive. Pan temp tells you what was going on 4 minutes ago.

Love my duel cooler. More confident when towing that im not pushing the transmission as hard. 200 pre dpf. Only issue I have is the xpodition cooncept catch can mounts in the way. I did modify the cooler to be on the driver side. Some threaded rod and nylock nuts did the trick. Closer to the condenser now. Holds temps cooler by 15-20 degrees. Drops temps quicker after hills when towing. Was wondering about fitting a 3rd pwr cooler and if it would be too restricted on flow. Or do u guys think that it won't effect it.

You won't need a third cooler if you already running our dual system as they are brilliant and work very well. You also still have the original cooling system working for you as well.

Just watched clip exellent content as always, just one question I have a 2010 V6 Hilux and I have fitted a single cooler a couple of years back and I also had a second cooler I won’t to fit now. Would the positioning of the in let and out let matter, I was thinking of joining them at the bottom’s so that they are always full of oil or joining them at the tops so that they drain when the motor is off which scenario would be best

[@WholesaleAutomatics]

Put the second cooler behind the first, run hot oil to the rear cooler first then into the front cooler. This would be the most efficient way.

[@neilrobertson6535]

Enjoyed all the information in your video . Do you do a cooler for the NX 2016 Pajero. I noticed at 90000km when I drained the auto it was very dark in colour. Decided to do a full system flush ended up using 20 litres. I will now drop the oil on a regular basis. I don't tow a caravan at all just a regular 6×4 trailer to the tip now and again. I have a device that i can read transmission temperature on my phone. I live in the hills and noticed it reads around 90 C max at the top, naturally this may change a bit depending on ambient temperature. There's a air to air cooler fitted from factory and presume made to the Australian conditions however fitting a extra one would be of some benefit iam sure.

[@WholesaleAutomatics]

Not as yet but we are going to be doing them later this year. We are looking for Pajero’s to do the development work, owner gets to keep the fitted cooler for free.

[@qaisibrahim5674]

Great video. I have a 150 Prado 2.8 GD 6 speed. Does the cooler kit work in combo with the existing water cooler in the rad or is it bypassed completely? When 4 wheel driving, I often see torque converter temps in the 110-120 and occasionally in the 130 range. Trans temps are considerably less but still sounds like too much to me. I dont tow, just loaded up 4 wheel driving. Cheers

[@WholesaleAutomatics]

It works with the existing water cooler, we try not to bypass when possible. An extra cooler will make a huge difference in your case looking at those temps.

what do use think about thermo fan on a oil cooler. i seen same with a electric fan on them

[@WholesaleAutomatics]

Not really required as the engine fan does this job fine and in most cases there is no room for a fan. We instead opt for larger coolers and in some case dual coolers to get the maximum effect.

[@NiznerolA]

I have MB GLS350d. I’ve had AMG instrument gauge software fitted to my driver information screen. Gearbox temp is always at 82-83 degrees, once up to operating temperature, no matter if it’s 15 degrees or 35 degrees ambient. That’s also whether I’m towing a caravan at 3100kg or not. Would you recommend a cooler in this situation, and more importantly, do you supply kits for a 2018 X166. Cheers.

[@WholesaleAutomatics]

We don't have a ready made kit to suit the X166 but I'm sure one can be made if required, however I'm thinking you might already have a decent cooler factory fitted. Benz tends to get things right first time round.

[@NiznerolA]

I'm fitting your kit to my px3 next weekend, any tips I've seen the installation video aswell

[@WholesaleAutomatics]

The fitting instructions a very good but the video is about to be updated as we have upgraded the kit and made a major mounting change that you will most likely have. In fact it is not an easier install. Half the video about removing the old heat exchange and replacing with cooler unions and lines is still the same.

Have you fitted an American Toyota Tundra 5.7 V8 ? (My year 2019) Models years 2019,2020, & 2021 Toyota left the transmission cooler out and the engineers say they tested and you do not need Transmission cooler. As per your video I would say that yes I need one. Would you happen to have a kit that would mount in front by the grill with a mounting Plate. ( By the way I have noticed that my truck runs better in cold days , Transmission runs in the 160F to 180'S.). Thank you Sir

[@aaronrees2437]

I have a 2020 ranger super cab. As a tradie am in it everyday and have just clicked over 85,000kms. Up until recently I had no idea about temperature in the auto. I fitted an ultra gauge to monitor temperature and After a recent trip towing a 19ft van had coolant temps of over 110’ and trans temps of around 114’. I had a faulty thermostat replaced in the coolant system And fitted one of your trans cooler Kits. My next trip temps in the trans didn’t get above 90’ and the coolant the max was around 100’ towing from Vic to Queensland. Definitely well Worth the money. My question though is what is an estimated cost Of a trans service and what is involved? The his is due to the fluid in the trans being black when the cooler was fitted. Any help Will be appreciated

[@WholesaleAutomatics]

Full flush transmission service using full synthetic oil is $495 inc gst Aaron. Replacing 100% of the oil, new pan gasket and oil filter. So it's a pan off job. However, for an extra $200 you can have the thermal bypass valve installed and that will make a huge difference again, dropping another 20c off what you have now.

[@aaronrees2437]

In the LC do you run the factory cooler alongside the aftermarket cooler or remove the factory one. Cheers

We run both the original and then our aftermarket coolers.

[@Always_Sundayx7]

I got one of your coolers on my amarok and it dropped the temp down from i think it was constantly 70ish to 50s. Time to upgrade and it will be one of the first mods ill do. Cheap preventive maintenance. Will you do one for the new F150? Thanks

[@WholesaleAutomatics]

We haven't had the chance to take a good look at the new F150 so I have to wait until I have. We will be able to do one for sure but have not had the chance.

[@David.William83]

Very interesting. My 2020 Everest 3.2L sits close to 100 degrees according to ScanGuage in normal driving without towing. Is that typical for Everest/Ranger? Why do manufacturers not fit better coolers OEM?

[@WholesaleAutomatics]

It is normal unfortunately but can be improved with a cooler kit and thermal bypass valve kit. We think they were deliberately running the oil at the hotter temperatures to thin the oil and this in turn contributes to reaching the all-important emissions and or advertised economy figures. However, the side effect of this was not being able to run the auto at a more favourable temperature.

[@paddy9507]

Rod does the LC300 GR have a standard transmission oil cooler? If so, does it need assistance for towing a 2.5ton van?

100 series fte 4 speed A. Best place to check trans temp? B. Should i remove/bypass stock trans cooler in rad and upgrade air to air one? C. Best place to learn about torque converter lock up. As I tow a 2.5t van often Cheers

[@WholesaleAutomatics]

In the front cooler union is the best place to check for the 100 series with 4 speed autos. Leave the original coolers in place, I really don’t think you need n extra cooler for the 100 series as they have great cooling system already. We have the current lock-up kit on sale now and are developing the new Nomad kit to suit late this year.

[@wonniewarrior]

Have a BA wagon and Territory. Both have the exact same engine, transmission and radiator. And guess what = both had the trans cooler in the radiator bust. Both now have a aftermarket cooler (not sure what brand or where from). Ford fitted them for me. And both went about the 170,000 km range on the odo. The BA itself had 3 flushes and cooler added. Mechanic told me the oil was black but because it was spotted early (dreaded pink milkshake) it was saved. That was 7 years and 100,000 km ago and still going strong. As for the Terry - it had same problem with Ford spotting the new radiators on a check up and oil was dirty (inside of coolant overflow showed signs of pink milkshake as well) so I opted a oil cooler on that as well. Car yard I bought it from claimed there was a new oil cooler fitted under the intake the lying bastard. Was not one there. That was 5 years ago and about 60,000 km ago. Only problem with Terry is it keeps stalling out at low speeds at random.

[@georgebets4128]

Question. Installed your dual cooler on 2016 bt50 6r80. Temps btw 50-70, tick Only question, why do you like them installed in front of intercooler on the outlet side of the intercooler?? Air passes thru hot oil cooler then that hotter air is hitting the intercooler and radiator. Would the better place be lower in front area??

[@WholesaleAutomatics]

We now mount our Ford Ranger cooler behind the intercooler well out of the way from any bull bar, winch and larger intercoolers. Works brilliant perfectly.

[@scottmorgan2181]

Hi, I'm about to fit one to my car, just a question as to do I fit it before the radiator cooler, after it or bypass the radiator one altogether. Seen a few videos and forums, and get different advice as to which way to do it.

[@WholesaleAutomatics]

After the radiator in all cases except the Ford Ranger/BT50 3.2L and Next Gen Diesel where we bypass.

[@craighkzn]

Hey Rodney..Craig here from South Africa...we deal with very similar temps when towing here, and im really tired of the dark Transnission oil on my PX 3.2 ranger....do you by any chance export your cooler kits and bypass valves to anyone in South Africa?? I can see a lot of opportunity for you here where the Ranger is a top seller...

[@WholesaleAutomatics]

Yes we do export to South Africa Craig and we have them on special at the moment but the sale ends very soon! You can order online including the freight to South Africa.

[@dinostocchero2347]

Hi , with he extra hose lengths and possible restrictions through the cooler does it affect the trans oil pressure in anyway. Cheers

[@WholesaleAutomatics]

No, not at all Dino and we test the flow rates during the testing stage of development. The new Next Gens run at 6 litres per minute which is quite high in comparison to most others and when we do a deliberate restriction test, they still run at 6 litres per minute. We don’t continue to restrict but we still do all the tests so we fully understand.

Hi Rocket, i have a TD42 GU with a RE4 & nomad valve body. The previous owner mounted the tranny cooler under the car. I've had to replace the fan twice because mud just kills them. The one it came with was an el cheapo and died from ingress, but the second was a Spal and the motor smelled burnt out when it died. Its a bit of a kettle so I dont really want to try and fit the cooler behind the grill. Do you have any suggestions, tips or things you have seen to prolong the life of my fans?

[@WholesaleAutomatics]

Rip the cooler that is mounted under the car and toss it in the bin and Yes mount a cooler up front. You wont need the fan.

Thanks for the video from Rhode island USA I want to know iui f you can add an oil cooler and bypass the stock one in the radiator 6l80 2016 Silverado,

[@WholesaleAutomatics]

You will most likely find that you already have an extra cooler factory fitted with the Silverado and you should be able to spot this behind the grill or by running your eyes along the cooler lines from the transmission and track where they go. If you heavy tow then yes I certainly do recommend an extra cooler but not so much if you don't tow.

[@user-qs1vg3dv1h]

Hi post watching this video I contacted your team as I had recently purchased a new next gen ranger and was interested in your product. I was however disappointed to find out that from his words that no R&D was down and he couldn’t tell me what temp drop could be expected - the response was they just work. I had also asked about where your analogue is situated- does it read T/C out temp or at least comparative to the OEM position -this again couldn’t answer or if a single core would be sufficient- a twin is better. My van is all of 3.5t and so far with standard setup using scan gauge max was 105c up a long range - to me acceptable plus given as others have commented engine temp runs between 90 t0 100c. Post the phone I was disappointed and confused, Appreciate if you could clarify my concerns.

I just watched a video from a Perth KZbinr with a new v6 Ranger who you supplied the cooler kit for, what sort of temps reduction would you hope for after installing the kit? im not sure if he has done something wrong with the install as it appears from his before and after tests using his scangauge ll that he went from running a ,max of 100' and dropped after installing the kit to a max of 93' he showed his average temps before were high 80's to low 90's and after the kit the average driving temps only went down by 4-6' is that normal? i would of expected a bigger drop in temps? has he done something wrong?

[@WholesaleAutomatics]

As he mentioned it has certainly made a difference but as the 10 speed runs though a thermal valve it will still shut the cooling down until you get up to about 80C mark but the real difference is when you load the car right up and the temp rise quickly. The oil coolers will do a brilliant job of controlling this and he no longer sees the over 110c temp that he was before.

[@omxn2392]

Hi, I have a 12HT 60 series cruiser with the 4 speed auto (a440f). Gearbox has recently been fully rebuilt, have installed your universal duel cooler and bypassed the radiator and replaced all lines from box to cooler and it seem to sit at around 100c-105c. Is the temp normal for an old box or is something else wrong? (Not towing) Cheers

[@WholesaleAutomatics]

The A440F range of torque convertors are widely considered to be the all-time most Inefficient convertor ever made, worldwide! If you installed our billet torque convertor into 60 series it would make a massive difference. Far less heat generated and about 13% better fuel economy.

No such thing as to cool here in Australia, The torque convertor will still generate heat and in the case of your 150 series you will still be running through the radiator so no chance of Ever being to cool.
