High engine bay temperature
Today I was driving my 2007 H3 around town and a few back roads. No speeds over 60. When I got home I noticed the engine bay was very hot. I have a thermal thermometer and the top of the crankcase was about 700 F. The exhaust to the header was around 2,000F. The gauge on the dash reads normal temp( half way). I hooked up my OBD reader and checked the running coolant temp. According to the reader the running temperature was about 200F. I also smell oil, I recently changed the oil so that could be the smell but not sure. I also park over a cardboard box so I can see if oil leaks. No oil leaking. My question is what could cause this issue
