where should my eot/ect be?

[excav8ter]

So I just got my truck back from getting new head gaskets, egr, oil cooler and a few other things, where should my eot/ect be? I have an Edge CS. Prior to all the work I would see a maximum of 18 degrees difference while towing 11,800. Today is the first day I have used it for pulling since I got it back and the difference between eot/ect is varying between 8 and 14 degrees. With the oil being the hotter. Is that normal? Seems like a big spread for all the work that was done.

When pulling a load, the delta is thrown out the door. At this point you only need to be concerned about is cooking the oil, dyno oil and synth have different temps when it comes to thermo break down. The other is not to let the coolant get to the boiling point.

Thanks Rich. Even when not towing I was occasionally seeing a 10 to 13 degree spread. It just makes me a little concerned that with all the new parts the spread is that much. I'm going on a little roadie with my rubber track skid loader at 3:30 am tomorrow. I will be towing about 11,800 for 400 miles. I will be anxiously watching my temps. Friday I am going with my wife and kids for about a 700 mile round trip for fathers day/anniversary weekend, no trailer just us and the truck. I will watch the unladen temps and report back.

Air temp today was 80, and I am not running my SCT yet. I want to get some miles on the new parts.

I can get a 20* delta when towing my 8k 5er up a steep grade. The protocol for delta check is a fully warm up motor (190ish), 60-65mph, flat road, hold steady for 2-4 minutes, unloaded (not towing), then check delta.

Did you ever figure out your stadegy/tune issue?

Do you know if they flushed prior to oil cooler replcement?

Or flush at all?

Yes I did. My strategy is still the same, so my tunes are good to go. Thanks for the help!

Russ (the tech who works on my truck) did headgaskets, egr, egr valve, oil cooler,coolant flush and oil change. Also installed the ARP's I dropped off. After my road trip with my trackloader tomorrow, I will call him and make sure all is well. I think I need to bring him a box of beer for all he did for my truck.

Let us know how it goes! Also, never hurts to grease the palms

Yes, it is always a GREAT idea to let them know that the work they did was appreciated. It's a tough gig to always be expected to know everything about these trucks, diagnose them perfectly the first time based on VERY sketchy details from the owner and never be able to interact with your customers directly. I LOVE my technicians who work on my truck.

Speaking of which, I need to take a day off of work and head over there to show them some love.

Well.... I did just about 40 miles yesterday pulling 11,000 lbs.


TFT stayed at 154-156 except for a brief spike to 168.
EOT got as high as 219, again only for a few minutes, mostly it stayed around 211-212.
ECT Rep and between 195-212.

The biggest spread I saw was 18 degrees on about a 1.5 mile long hill. Most of the time the spread was 11 degrees.

Does this seem OK? Tomorrow I will be going on a longer trip unloaded, I will watch the temps and see what they are like .

Thanks, Ben.
