ECT EOT questions

Hi all, I have a 03 F450 CC auto with 12ft flat bed and 4:88 rear end,
after Scangauge II installed I've been watching my deltas and this
is what I've been getting on flat run to town 40 miles with 100+ outside temps cold start are within 2deg allways, at warm idel wt172 - ot173
at 2500rpm 68mph wt206-ot220 and trip home wt213-ot229, I did the coolant complete flush and clean and got the same readings. pulling the camper up the mountains and not much different on the deltas, my ? is
would the size and design on my truck have any difference for the deltas
or will I be needing a oil cooler soon thanks

What did you do to flush? Did you use the Ford flush product? The way it looks if you did, that YES, it's gonna be soon to do a EGR cooler and engine oil cooler replacement.

Definitely looks like a plugged oil cooler. Change it before you blow the egr cooler.

If you arent seeing over 213/229 towing in 100 degree weather I would say your fine.
If that eot gets over 245 towing get a new oil cooler.

I have 4500 miles on a new longblock and my delta was alot higher 192 ect/270eot.....with no dash warning lights btw.

As long as you ect rises, and the high speed fan comes on at over 212 I would drive it and keep an eye on it. Just my. 02

I finally have the right formula for the Torque app (I think). I drove in the mountains - lots of 6% grades and am seeing about a 20 degree delta between ECT and EOT. Outside air temperature was 90 - 93.

At one point climbing a long hill, EOT climbed to 243, ECT was 215 or so.

I think you're right on the border line. Probably good for awhile but if it gets any worse then you'll be rolling the dice every time you drive.
