Highest recorded eot ?
I recently started having coolant loss while towing 5th wheel camper, got an eye opener when I saw ECT of 197F and EOT of 278F within 10 miles of non towing while monitoring with a Mac scan tool. Has anyone else seen temps with this much differential ?

"Post repair"? Surly you mean "Pre" before repair.

Nope. I meant POST (as in AFTER) repair road test. The vehicle came in because it wouldn't stay running. After replacing the engine harness and repairing THAT issue, was when I observed those temperature readings. The customer has already been forewarned about those temperatures. Whether or not he chooses to address it, is entirely up to him.

I'm hoping that the oil temp sensor is not reporting correctly. Tomorrow morning I'm going to check when the engine is cold, I would think that both temps should be real close to each other before starting?

If you have doubts, try swapping the sensors to see what readings you get. They are both literally identical.

How are you guys checking these temps ?,,I have an 06' F-350, 6.0, with 52 k on it,,no issues at all so far,,,,But,,,by reading all these EOT and ECT threads,,I think I should look into it soon !,,Maybe some Info Help ??,,,Thanks,,,Mark
PS,, I have seen the collant filter mods,,,and where they mount,,,I happen to have a Snow Plow power solenoid in that same location,,A filter may still be able to be mounted there!

I have heard that the Mac scan tool's EOT reading can be off by a lot. Is there any truth to this?

Installed new oil temp sensor yesterday for funzies, same results on the EOT (275 degrees). Looks like I will be tearing it down and doing the oil cooler/egr cooler replacement ASAP. While I was at the dealership the parts guy said that the service department may be able to help out some since the truck is only 8 months out of warranty with 57K miles. They were shutting down at noon so I will check back on Monday.
