Eot vs. ect in cold weather

[chicub13]

I just recieved my edge insight and noticed that I have steady ect of 176 and eot of 210is and the outside temp has been 18-25°F so is a problem with the oil cooler or does it look like it cause the truck is not getting to opperating temp?

If the gauge is correct, the T-Stat is failing. You should be able to get another 10* warmer even in colder conditions. Regardless, you still show a high delta! Replace it and test the delta again at cruise. If it is still high, don't wait too long before replacing the oil cooler or it will cost you a lot more in repairs.

Even if I don't have an egr cooler it should still get warmer then?

Yes, do as suggested above. Make sure you check the two readings after siting overnight, they should be within a degree or two of each other. It is a good idea to get a coolant filter asap. It's likely your oil cooler is clogged, not good.

Sent from my phone that somebody didn't help me get.

You have a failing thermostat and a plugged oil cooler.
Even when the ect goes up to the normal 190*, the delta will be 20*... Way too high and is in the RED zone.



Flush with Restore, Restore+, Flush ALOT, drive a day or two, then replace Oil cooler with a new one!
