ECT 192 EOT 219

[demott930]

I'm running 75 mph. It's about 88 degrees. Is 219 EOT way to high. I know I prolly have an oil cooler problem. Truck is going to a diesel tech I know after fathers day Weekend/ Diesel nationals in Indy. Getting EGR delete new oil cooler head gaskets and head studs.

Fist off your not doing the test correctly. you have to run 55-65 unloaded on a flat road for approx 30 minuets. If your replacing it then I wouldn't worry about it for now.

I tested yesterday coming back from the beach. Three hours at 65-70 and got 20-25* deltas. ECT ~192 EOT ~215
All I had was a couple hundred pounds of crap in the back. Do I need to replace it?

how hot was it outside? i got mine up to 230 eot but was like 90 out

It was 80-82 or thereabouts.

The test is 55-65 mph, unloaded, on flat road for approx 30 minuets. (EOT has to be above 190* before you start the test) Anything else, even if the numbers are close, is not accurate for these testing purposes so saying I was doing 75mph for 3 hours does no good. its not accurate.

then in that case my cooler isnt plugged? its 15* ish at that speed

Yes your cooler is plugged. You should be able to run 75 for 3 hrs without the temp delta exceeding 15*.

I second that statement.
