Why the Ford 6.7 Diesels Run "HOT"

[@jJovel-lx2qr]

I have a 2022. I tow a lot and always keeping track of my temperature, I had seen engine oil temperature of 236 and transmission 221 before the fan go crazy, I was a little concerned about thos numbers till i saw your video..Great information. Thank you.

[@Pyro1472470]

Bro thank you!!! I’ve been seeing 230’s trans tempt when towing and freaking out. So glad you explained all this

[@briancrowley7699]

I really appreciate you making this video. I have a ‘17 and I tow within the truck limits but often see trans temps above 230 on big climbs. I was worried because those temps just didn’t seem safe. Seeing the stock tables really puts me at ease. The truck is doing what it is supposed to do. Thanks again.

[@vid1fl]

Dang I have yet to get to 221. 205 207 on the engine and 203 205 on the trans. That’s me not towing going 80 on the highway. I then sit and idle and get the temps back down to 196 engine 194 trans before shutting it off. Glad to know I haven’t even scratched the surface when I start towing!

[@MattSoppa]

Good insights. Saw your post to this video on the 6.7 Facebook group. I have a 2011 and have towed multiple times in 100°+ and even up grades in that weather and never heard the fan like I would on my old '06 6.0

[@jasonkubitz9410]

Finally someone that gets it. I was concerned when I bought my 2017 and did my first tow with my toy hauler. Temps went soaring fast. They came down faster though. My fan doesn't kick in until I hit 250 on oil temp. I actually spoke with a Ford engineer for the Scorpion engines and he said the same exact thing you are saying. They set these parameters for efficiency and they can well exceed these temps without any problems. Towing at those temps several times a year can put you into the severe duty class. I change my oil every 5K with Rotella T6 and changed my trans fluid at 30K. I will change the fluid on both diffs when I hit 50K. One thing to look for on these trucks is the upper oil pan leak. I just had mine fixed for the second time. If it leaks one more time I will file for the lemon law. Kind of a bummer since I love my truck.

[@Darmstrongfishing]

What’s the lemon law cause my truck is doing this

[@jasonkubitz9410]

@@Darmstrongfishing Typically if you have to have something fixed 3 times under warranty, the OEM is required to buy your vehicle back for the price you paid. After 3 times for the same repair it is deemed unreliable. That's what I've read but I'm no lawyer lol. It may vary state to state but I'm not sure. It also depends on the type of repair. So far I'm on my second fix for the upper oil pan. If it leaks one more time, I'm filing for the lemon law

Is there a way to adjust the temp at which the fan comes on? My truck is a cab and chassis with a service body that runs at least 15,000 lbs all the time, even more if towing. I don't hear my fan come on full until I see about 3/4 on the temp gauge. Thanks!

[@douglastotten9555]

I have a 2015 F350. Pulled my 12k trailer up a pretty serious grade. It was 74 degrees outside. My engine oil temp hit 247. My coolant temperature went up to almost 3/4 of the gauge. When I crested the hill, the temperatures came down quickly. I did not hear the engine fan engaging. I know my parameters were acceptable, but is it normal for it to get this hot low ambient temps. I’ve only pulled with it once, but it’s a freaking horse. I live in Nevada and it will be over 100°. I just want to ensure that I’m not gonna have any overheating issues. Any comments would be appreciated.

[@JaegerWrenching]

That is not normal. Is the truck tuned? Tuning can produce higher coolant temps and thus oil as well. Also check your coolant level, make sure you're full on both expansion tanks. Look for debris between the radiators. I tend to see a lot of leaves and trash buildup between the two rads, also bugs and rocks tend to get stuck in the radiator fins themselves on higher mileage trucks. Remove your plastic rad cover and look between them, shine a light on the backside and try to look through the radiator fins. These work well for cleaning them out: www.napaonline.com/en/p/BK_RG1002BK?cid=paidsearch_shopping_dcoe_google&campaign=GSC-Tools-Equipment&campaign_id=8553470562&adgroup_id=107047174069&adtype=pla&gclid=CjwKCAjwg-24BhB_EiwA1ZOx8jvOkEZz4UJb_HAo0bH7-mSRE312IQv535upJRVHGco-CaG7vxrTERoCVsgQAvD_BwE&gclsrc=aw.ds&gad_source=1

[@ms.annthrope415]

Seems like Ford really designed and engineered a great engine, a real towing machine. I bought a new '17 250 6.7 not because I tow but because I enjoy road trips and want an engine that can muscle through just about any grade or temp without puking. My late dad always told me to always get the biggest engine you can afford. The weight of the vehicle and air resistence remain the same. A larger engine works less than a smaller engine. I've seen so many vehicles in southern California climbing Tejon Pass pulled over with steam pouring out from under the hood. Granted, most people don't take care of their cars and let it disintergrate. The signage says to turn off A/C and drive easy. I would drive up with the A/C on, comfy, and never even came close to heating up, passing everyone. So I'm glad to see that Ford made the 6.7 a great engine.

[@6.7Pstroke]

I just got back from WV and I noticed my coolant temp reading popping up from time to time wondering wtf!? Lol thanks for clearing that up! How about oil temp? I was at about 215-230 towing.

When I'm towing in b.c up long grades in summer I've seen 244 deg. On the oil but the coolant stays around 220-225deg. Do you think I should run a electric oil cooler fan? Or would a duel oil filter and deeper pan ?

[@tonycardenas7235]

I have a quick question? What is Ford’s desired oil temperature and what really is the sweet spot? I see coolant and transmission. I just want to make sure about oil. Because I live in Central Texas and it’s hot! I would really love to know! Thank you for the video!

[@JaegerWrenching]

Within 20* of Coolant. IE coolant = 220 oil should be 240 or less. Oil is cooled by coolant therefor it's temp will never be lower than coolant except during initial warmup. Bad oil coolers will cause higher deltas.

[@imasimpforurmum472]

What about oil temp. My oil temp gets into the 240 range when towing my 40 foot camper which weighs in 12,000 range. Is this something to worry about. If so how do I fix the problem

[@jamiesami2000]

Mine runs 235° EOT with my 30ft 9k camper here in Louisiana @70mph on the interstate in the peak of summer (108° heat index) These temps are fine as long as your running a good oil like T6 Rotella there oil is rated for over 300°. If your still worried mishimoto sells a low temperature thermostat that drops by 5° or check out SPE performance they sell one that drops by 15° to 20° on ECT and EOT.

[@vikp6115]

What happens when you sit in traffic with air to liquid? There is no air moving , will it overheat ?

[@JaegerWrenching]

You have a fan that pulls air through the radiators while sitting or moving. If your temps were getting to 280 you have an issue with coolant flow coolant fill or air flow... Most trucks that have some miles on them get dirt and debris on the radiators blocking/inhibiting air flow through them. I recommend removing your front grill and thoroughly cleaning your radiators "there is two of them" with a pressure washer until water flows easily through them.

[@duner1972]

I wonder if you can answer a question nobody else has been able to help me with. I have sensors on my water as well as air temps. Do you know what the max air intake temp should be going into the motor after it comes out of the cac?

[@JaegerWrenching]

There is no max temp and it'll run with very high inlet air temps. How ever your turbo will outlet 350* air temp prior to the CAC. A good working CAC should be able to bring that down to 150* or less. Tuning and total airflow through the cooler will changes these numbers a little. Hot tunes can get turbo outlet temps into the 450+ range and post cooler into the 160-170s. Boost Derate happens based on a specific boost number and barometric pressure as those two things dictate exactly where in the turbos compressor map you'll be operating and thus how efficient it is at compressing air at that exact point. More efficient = less heat generated or lower turbo outlet temp, less efficient = higher turbo outlet temp.

[@duner1972]

@@JaegerWrenching thanks for all of the info. The problem I'm having is I'm getting about 405° out of the turbo and then it's still up to 225 after the CAC.

It has gotten better after switching to a soft so I can run stock settings. I just didn't know if putting an aftermarket CAC would help. Even in stock mode, I have to fether the throttle to keep egt's off of 1500

@@duner1972 Put a 2015 andup[ turbo on it. That SST turbo is great for down low but it doesn't have enough air to clean it up. Those number are pretty norma for longer pulls and with a heavy load.

i really wonder if that is done for efficiency reasons only? for example the emission sytems likes heat, along with other various efficiency reasons. But is it ideal for the longevity of the engine an trans? this is where im not convinced it is not! million mile trucks arent running at 200+ all day long!! the entire racing industry is constantly trying to come up with better ways to control heat instead of making it an acceptable thing, which is what i feel is happening here with the main reason being to try to make the emissions system more efficient. who cares how long your truck lasts. they sure dont, they'll be more than happy to sell u a new one when u reach 100k!! we spent the last 20yrs putting bigger coolers for trans, engines, intercoolers because of premature failures now we're to assume this is acceptable! not buying it, the #1 enemy of an engine an a trans is heat an that didnt change overnight? what did change over the last several yrs/decades is vehicles being disposable "run it till it breaks then get a new one essentially" instead of trying to make them last a lifetime

This is my factory ford tune prior to doing anything with EZ LYNK. Which I’m no longer using now anyways. No alterations or table adjustments have been made in this file. This is FORD’s file, well technically... I want to address this comment as if people don’t understand how this works. After I purchase this truck I own everything with it including the tune. Same goes for buying a tune from a tuner for EZ LYNK. I own the tune, but most tuners lock their files so you can’t read them. Which is fine but legally you could take this up in court and here’s how it’d play out . They’d come up with the purchaser/owner of the tune not being able to copy or reproduce the tune but you’d have full and complete access to your tune. Somewhere down the line this transfer of ownership has gotten lost over the years.There was a big deal about this exact issue but modifying software on smart phones. The supreme court sided with the purchased/owner, saying they own it they can do what they please with it. Most of these tuners started with someone else’s tune and adjusted from there. I find it ironic that they are worried about what gets out but they didn’t care when taking someone else file to start with. I will continue to show data I legally own and I will continue helping people understand how it all works. If you’re worried me or you think somehow I’ll benefit from looking at a file like it magically gives me or someone the ability to tune properly, well you are surely mistaken.

Air to air intercooler is far superior in cooling over a water air intercooler. If they ever fail, your motor is now toast. John Deere use to use a water/air intercooler on their engines from the mid 90's and older. Then they switched to a air to air like everyone else. I have a 17 F350 6.7 And a 14 Ram 3500 6.7 Ram take's about 22% less fuel runs cooler and has a lot longer service intervals then the Ford doing the same job.

[@JaegerWrenching]

You're comparing an inline 6 to a v8... also you saw tractors engines change intercoolers over the years so that automatically means one is more effective than the other?.. Here is why your inline 6 gets better fuel economy. Anything with an inline 6 has an edge over a v8 because the crank doesn't require any counterweights. This is because Inline 6 crank journals cancel out primary and secondary vibrations naturally, thus no added counter weight is required meaning, more power and torque is transferred to the flywheel with less input, or fuel burnt. It's a apples to oranges comparison unless you only care about fuel economy and to which the inline engine is better. If you care to know or understand why i say air to waters are more efficient it's because water can carry more heat away because of its density. So air to water intercoolers can move out more heat in the same size intercooler, this is proven. You also get a more consistent charge air temperature with them meaning the tuning window can be narrowed and you can really dial in the tune, again gaining some efficiency. They also require less piping from turbo to intake reducing turbo lag. But As far as overall parts to fail they have many more and will fail more often. This is probably why you saw John deer move away from them as failures on tractors is bad for business. They can also freeze and destroy your engine if you use water in them which i'm sure people did.
