UNDERSTANDING THE DELTA IN YOUR POWERSTROKE

[@J.Chaplin]

6.0 Owners stare at their monitor more than the Road!! 😂😂 Great Video Bill! But I’m still gonna be looking at that SCT X4 every 37 Seconds!

[@kcdaniels58]

Haha...I do that all the time...

[@brad11344]

One smart man on these powerstrokes. I wish there's someone like him on Duramaxs

[@timgring4121]

I was actually one of those people who was nervous about the deltas until I watched this video. Thank you Bill!!

[@tyhewitt4858]

Thank you for the simple explanation! I love working here! I learn something new everyday and love talking to all the different customers!!!

[@Arriba-las-nalgas]

Do you guys sell the “tuner/tuning” separate that you guys install with the dealerproofing?

[@noecruz9265]

That's a great point of discussion Bill. Kudos to your wife for inquiring about the delta!

[@joshsage]

James gandolfini has a living brother. Great and helpful videos. One day I’m going to blow up my 6.0 excursion and have Bill dial in her in. Did wonders for my buddy DJ from Alaska. He drove it back, like a champ.

[@SALTYDATTO]

Love the breakdown. Towing up here in Utah during the summer really made me realize and understand how altitude, humidity (What humidity), and outside temps really come into play when it comes ensuring my ECT and EOT ▲ is within the threshold of a healthy cooler. Like you said Bill, it all depends on whether those temps come down after the increased load.

[@nativeoutdoors1780]

Yeah same thing as I noticed driving my diesel through utah, outside temps are huge on what the oil Temps and coolant Temps are

[@shawnmoore5621]

Hello from Idaho, You are the greatest my friend! Love your videos!

[@larryeaton7384]

Very good information to a diesel lover. I, O will put it to work for the longevity of my beloved 2002 f350 7.3 powerstroke. I have studied and rebuilt various parts to my "BUFFORD" for the satisfaction and comfort of knowing what is happening in my 7.3. I have hauled RVs from coast to coast and the California hills and climate will through you for a loop if you do not know your Powerstroke! Hands down and facts are essential to a diesel lover such as myself. Fact of the matter is if someone were to offer me a new replacement for my 2002, 7.3, I would probably grin, spit and snicker in that order. You guessed it, I LOVE my TRUCK!

[@jimfuller5309]

Hi Bill! I just met Ti..super nice by the way good to see her at the shop! I had my big black 05 dually in for a bad IPR valve. Mike and Scott of course took great care of me! I was just thinking about that delta thing yesterday and now here's a vid. I guess my truck is fine my eot never gets that high even pulling the camper. My truck is my baby and I worry about it like a kid lol. You guys are the best. I've never seen any shop that takes care of their costumers like you do! One of these days I'm gonna bring my 76 F-100 up there. It's a cool truck I put together. Anyway, Cheers!!

[@vincehilaire720]

Good video, Bill! I had wondered about the instantaneous delta under load, and you addressed the issue perfectly - thanks!

[@jebbusk4805]

Thanks for the vid, I monitor both these temps in my 05 6.0 excursion...the delta is almost always 8° running around normal and goes up to 18-20° pulling steep grades loaded with our gear and camp trailer. I never worried abt the difference because it would almost immediately come back down to 8° after topping the grade.

[@joshuamorrison1624]

Several years ago I bought a very well taken care of '03 6.0 with 138k miles on it. Shortly after purchasing I started getting a check engine light anytime the truck was pulled hard that went away the very next time the key was cycled. I had tried to check this code several times but diagnostics showed nothing. It wasn't until I started running a controller and monitoring my temps that I realized at 30° delta I would trip the engine light. An oil cooler and add-on coolant filter later, a high delta was around 20°. I HIGHLY recommend a controller to any new diesel owner just for the simple fact that you can monitor anything on the truck that puts out an electrical signal. It also increased my mpg's as much as 5 mpg (driven sensibly). Definitely worth every dollar.

[@paullamb7744]

Thank you to Mrs.. Lamb for pointing out this needs an explanation I learned quite a bit

[@alanrogers7442]

Such a very well educated and inspirational guy... thanks from all of us do DIY GUYS ALL OVER - BIG AL

[@Nate-dk8gk]

I am glad you put a name to this. Thank you.

[@bobuncle8704]

Clearly and succinctly explained. Thank you

[@mattreb5748]

I was towing my 15k fifth wheel up a 7 mile very very steep grade, semis have to hit there flashers on it. I saw 240 by the top, truck is a 16 6.7 powerstroke, it started to cool off even before the climb was over. Glad I found this video

[@joeysprojects9081]

Hi bill, love the channel. Ive learned a lot from watching it over the years. I am a heavy equipment mechanic in the Air Force as well as the fleet manager, uncle sams employees are stretched thin. I work on mostly construction equipment and hydraulic systems, and we have a fleet of super dutys, half of them 5.4’s and half are 04 duramaxes and 2 6.0s which are junk of course. We have 4 6.7s which are great but sit a lot, causing issues. Nevertheless, I own a 2016 f250 6.7, deleted, 200hp tune, baby it and never tow. I run archoil religiously and just bought their new formula. I rarely tow. I run clean fuel only, and I have a disaster prevention kit for the cp4. This truck has never skipped a beat, bought it with 10k miles in 2018 and now have just hit 70k miles. I drive a lot, but where I live is a lot of backroad, which is why I deleted it, because the truck would want to regen but couldnt. In the winter, on my drive to work which is about 10 minutes, the truck just barely reaches operating temp. I have an oil pan heater that warms the pan up at 1am, for when I start the truck around 5:30AM. I’m worried about engine cycles. I understand this might accelerate the wear of the engine greatly, i’m starting to look at 2017-2020 diesel super duties to trade mine in for, because at 100k these trucks lose value heavily which im sure you know. I could trade this truck in for about 42k right now. I owe 7k on it which i’m going to pay off soon but I just bought a house as well. I guess what I’m asking for is your opinion, would you advise getting rid of this thing before it hits 90k? Or should I just keep it? I appreciate it.

[@frankmjr6571]

I no longer own my 6.0L but still enjoy your videos after all these years.

[@DieselBadger60]

I could watch these videos all day every day

[@GovG33k]

Good explanation and reminder. We just got back from a camping trip and climbing Pacheco Pass with our 40' RV and '04 bulletproofed F250.The Pass itself isn't so bad, but in 110 degrees is can be very concerning to watch that delta spread (using the torque app) 20+ degrees. But it eventually went back down to under a 10 degree spread on the flatland afterwards.

[@Michael-hg2sq]

Thanks for the info! Still enjoying my 2006 F350, which I picked up in 2019.

[@tommark7615]

I was pulling a 37 ft. 5th wheel up a long steep grade with my 6.0 ford when I noticed a light on my dash check gauges. Checked my scan gauge and water was at 240. It never went over that .oil was 260 more or less topped the hill and temps. recovered pretty quickly. Never lost any coolant .fan was fully locked up. All in all I was pretty proud of the old girl.

[@stevetekrv5791]

Just found your channel yesterday. Damn I've learned SO much in just a few videos. Thanks!! Glad I subscribed.

[@TheBurnsStuff]

Your wife is going to be a wonderful asset to the business, Bill. Its going to be interesting to see what other video ideas come from her. Thanks for this video! It was great information.

[@SunriseCrawlers]

Thank you for the video. I have a 1999 7.3 and I did notice that my oil Temps where hanging high. I hit 260 oil temp towing. And regularly hit 220 without towing on a nice hot day

[@drewsharps8179]

Thank you Bill for the time you take to make these videos

[@coderedfit]

I drive my wife crazy with this stuff every time we haul our fifth wheel camper. Thanks Bill!

[@dylanhicks7996]

[@markneal3540]

You're the man Bill. Thanks for the info

[@mikeharlow2908]

Greatly educated as always! Thanks Bill!!!

[@josephhernandez7251]

Good video, Bill. This reminds me of my heat transfer class back in college. The video highlights the importance of filtration and maintenance of the cooling system. After so many heat cycles, precipitates will form scale on the heat transfer surfaces. In technical words, fouling. This reduces the efficiency of heat transfer. And if severe enough, inhibits heat transfer.

[@mdevidograndpacificlumbera1539]

What can be done about the scale?

[@cobraadam]

This is a smart man. Coming from an air force physicist, I can say that this guy knows what hes talking about. He may not know the mathematical constituents, but he understands the concepts and can think critically. They dont teach that in college. I used to be a Ford tech and I wish these videos were around when I was a tech. Very informative. Good Job! I love watching these.

[@darrenpendergast6658]

Bill you need to post more videos. I ditched my 6.0 for a Duramax! Im stil addicted to the 6.0 knowledge keep it coming!

[@lloydmarche7263]

I really enjoy your videos. Great presentation.

[@andredowner6932]

Bill! Thanks for all that you do for the community. Now that you have officially given up on the 6.4, would you consider adding support for the 7.3 again? ;)

[@Pilotdude3407]

Pulling my 17K camper up a hill, it will jump my oil to 230 and when my coolant goes to 220, it kicks the fan on and will drop it to 205ish and my oil temp will slowly start coming down. It’s scary looking but it works. Nice video Bill.

[@josephcirelli9642]

As always, you are a wealth of information for the diesel community!

[@antonioaa8097]

Thanks for the explanation. This happened to me when pulling a trailer up a steep hill during the summer. The temperature did come down but got me worry as the oil temperature when above 236 degrees.

[@thomasbarlow4223]

Bill you are the best.... thanks brother

[@lamarzimmermanmennonitefar5269]

The old a4-236 perkins does not have a cooler. Used in a lot of Massy Ferguson farm tractors. A lot of John Deere utility tractors have sandwich coolers. 4 239, 4 276, 6 359. Ive seen a lot of the 6359 with the paint discolored on the block from what I'd guess is inadequate cooling

[@1marlojenkins125]

Thanks alot Bill for so much knowledge. I've learned so much about my 2011 6.7 Powerstroke. #archoil

[@codycool16]

Bill, the 310 Waukesha motor that was installed in a 1755 Oliver did not have a oil cooler. It was a 310 CID with 85HP. The 1955 Oliver tractors that had the same motor were turbo charged did have a oil cooler. So yes there are diesels that did not have oil coolers.

[@jimv3352]

Anyone that has had their diesel truck, and uses it as a truck, for more 6 months should already know this. But there's always that 1 guy! Great vid Bill

[@hansw4692]

Very good video. Thanks Bill. Just the fewest guys actually try to get that far into detail.

Thanks Bill, great explanation

[@ronmoo2932]

Great info Bill Thanks a lot

[@biker1958]

Great explanation about this.

[@joerogersthird]

I understand the delta i just wonder what safe oil temps are when going down the road for a 6.0 my semi’s run 230-240 degrees depending on load and grades and I’m always heavy. But that seems a bit hot for a smaller Diesel engine. My temps run depending on speed and outdoor temps 5-12 degrees running 75-80 mph in 90-100+ degrees idle is 2-3 degrees difference

[@tejanohotshotr6266]

Great vids. I am OTR hotshot, 2012 F350 6.7L 231,000 miles. I messed up royally, Had a coolant drip, DOT sees this and they will place me out of service. Did not have time to fix so my genius ass put coolant stop leak in. Stopped leak, good to go, so I thought. Hooked up my 40' gooseneck and off I went to my pick up point. I don't have a numbers ECT gauge, it just reads L or H. It stays in the middle so I am assuming about 200 degrees. Well my ECT stayed about 200 degrees and my EOT went up to 240 degrees on flat highway. Guess what is being replaced this morning? Yes, oil cooler, that stop leak don't play, so don't play with stop leak.

[@countryautobody7079]

Coolant maintenance is important I have a customer with a fleet of 6.7 rams and they all have needed the heater cores replaced at 250,000 miles due clogging up from never changing the coolant . I'm surprised the oil coolers have survived .

[@scottharrell7135]

Thank you for the educational

[@billmccoy4535]

Please make a video how to change front cover to intake o ring I can’t find a video on how to fix that leak

[@kirkbobo1363]

I have a 2000 7.3 Diesel and on long pass pulls oil temp peaks at 210 -215 degrees but cools quickly to around 195 and transmission fluid temp raises to 170 but quickly returns to normal 157 degrees on flat road. Using synthetic oil engine and synthetic fluid transmission. Often worry about rear differentials oil temp during long summer highway pulls with a cab over camper 9 foot loaded There is no sensor on diffentials. Obd monitored to phone app

What’s the reason of the dislikes. I just don’t understand. He’s giving his information to help people.

[@MrTommy001]

I think some people only know how to HIT the dislike. I see this on SO many videos that make absolutely NO sense!

[@bannablitz247]

What is a reasonable max oil temp and ECT EOT delta? The change in these is as you said to be expected, however where should you start getting concerned. Particularly my question is in reference to a 17 super duty 6.7.

[@leewebb7]

Good video by the way..

[@EarthRoamingAdventures]

We have a 08 6.4 EarthRoamer but was recommended to change to standard coolant because in remote places we could not gold in local gas stations. This did happen in blending Utah when a older hose ruptured and we lost coolant. What do you think go back to Gold or carry on with green standard. Love the vids by the way. Chris.

[@nativeoutdoors1780]

Always good when a whiteboard gets busted out, well taught though by the way!

[@nvtenterprisesllc6354]

Ok I have a 2017 ford and I pull a lot of weight about 85% of the time, now I’ve seen my ect at 230° and Eot 250° some time higher depending on the wind and mountains, So my fix was a high flow low temp thermostat so far it’s doing great but the temps still come up often depending how hard I drive her. Now my other question is am I ruining this truck by not running factory specs? Truck is deleted , no EGR‘s , cold air intake and I’m fixing to have a upgraded hot and cold side piping. Please let me know your answers

[@stevenbrooks1243]

Good video Bill 📹 👍

[@brandonmorrison1209]

Good stuff Bill👍

[@christopherwedemeyer2993]

So when do you worry? At what temp do you worry about the oil? 250? I was told there is a critical temp for everything. So what is critical oil temp? Coolant temp? Exhaust gas temp? My '01 7.3 cruises around with egt around 650-700. Pulling a trailer with tractor and bush hog on it (about 12,500 lbs) egt stays around 950-1000 degrees. Am I about to burn a piston? Melt a valve?

[@duanelam6481]

Great video thanks for all of the great information. I've been looking through your videos in regards to the PCM. I have a F350 6.0 with 50k miles We deleted the the EGR cooler by putting plugs in each end and also used a SCT X3 tuner. The reason we did this is because my turbo locked up or the veins locked up in the turbo so I thought while replacing the turbo we would delete as well. But now I have everything back together the truck runs great for a short bit and shuts down and the tuner tells me PCM keep alive memory, sorry I don't remember the number. Any recommendations?

[@dantheman20127667]

Would you say that a 10-12 degree delta on the highway with no trailer is a problem? Flat road no hills

[@Ricky1Feather]

Good question, just had a new engine put in and get delta like this

[@michaelsacy]

Wondering too

[@snomofilms]

9 times out of 10, 90% no more!

[@SlipperyDucky]

Ford tells us 12 degree delta we need a new oil cooler. Does having an EGR delete change that reccomendation?

[@Asphaltrejuvenator]

Great info man thank you !

[@williamshultz3598]

Doesn't Ford say that the oil can go to 250 some degrees before it de-rates the horse-power of the motor. Running in South Dakota at 80 mph ( and that is the speed limit there ) pulling a trailer in 115 degree heat. We had sustained deltas of 40 degrees sometimes. As soon as the load came off the motor it would come back within 10 degrees.

[@bennyribs]

Got myself a front row seat for my first class at PowerstrokeHelp University!

[@robbkiker6861]

Hi Bill. Thanks for the explanation on the Delta. However, I am old school and in older vehicles you had a problem with coolant temps at or above boiling point (212). Obviously it is now different. I have noted the EOT/ECT on the tuner since your dealer proof of my engine (very happy with it) and on some hard pulls have seen 215. The stock engine temp gauge seems to indicate this is fine. So, what temp for ECT is considered too high for the 6.0?

[@aaronlyons1212]

Great thanks for clarifying that!!! Is there a max eot to work with?

[@parkcityrecordcompany728]

How about explaining how delta relates to good and bad head gaskets?

[@BIGBADBOW]

Thanks that's what I was freaking out about😂😂

[@ThisPartIsAndrew]

I have often thought to myself how complicated these machines are and pretty much the only thing keeping them from overheating is 100 year old thermostat technology

[@powerkingspowerstroke1405]

So I was pulling a trailer full of furniture from moving and my delta was 60 degrees off, no idea how I didn’t burn the fucker to the ground. But the oil temp was 260 and the coolant was 200, but it cooled back down after pulling the hill. Do I need to replace my oil cooler? Also been having issues with the egr cooler and maybe that has something to do with it too. Figured I should probably delete it and replace the oil cooler while I’m there but that’s more money down the drain

[@lllateralus]

Bill, have been following for years. Thanks for all the Powerstroke knowledge. Do you happen to know if the Cummins 8.3 ISC in my diesel pusher RV has oil squirters below the pistons?

[@drryan8426]

All modern engines have oil cooling pistons even Harleys form the early 80s. Diesels need them even more.

[@leronsimolke6899]

f250 06 eng stops hard to start oil over full but did not add , oil thin

[@outdoorzone]

Great info!!! Thanks

[@brendasmith5937]

Bill I realize this isn’t a comment or question about the delta, but have you ever done any kind of retro fit for a cabin air filter in a 7.3? I really would like a cabin air filter.

[@drome010381]

Finally someone throws the delta gauntlet down!
