Ok just bought my truck and had a question.
My ECT and EOT run a average of 9 degrees off of each other while driving normally. ECT is about 162-164 and the EOT is about 171-173. Pulling hills the difference will go up to 12 degrees.
Pulled a very steep grade up to my house while pulling my jeep (4700 pounds) and the difference was about 15 degrees and my ECT was about 182 while EOT rose to 196.
Is this normal or is my oil cooler clogged and in need of replacement.
Any suggestions on which coolant to buy?
O yea, it has egr delete but does not have a proper tune to turn it off. check engine light is on since the egr is gone.
