6.4 Coolant/Oil temps
Today I was driving up a pretty steep long winding grade. I'm deleted and have an H&S on the mild tune. Anyways I got on it to merge into traffic and on my way up this grade I noticed my coolant temp began rise above the normal (192-198F) range. It was starting to get into the 210 range, then 215-220 range. my edge evo (gauges only) gave me an engine oil temp alarm at 230 degrees, shortly after this I hear the engine fan kick on hard, the coolant temp was about 220F and the oil temp was at about 230 the entire way up this hill. It was probably 90 degrees today. The minute I start going down the back side of this hill everything returned to normal.
Since then the coolant/oil temps have stayed right where they've always been 192-198F +/- 4 degree variance between both temps.
Could this be a bad oil cooler or just the fact that it was a steep grade and it was pretty warm today? Also had the A/C on full blast.
Any insight would be much appreciated!
