2.4L 2004 Temperature Problem
Pretty much lost at this point. Before I begin, I've searched this site for answers or anything that may help and I've found nothing thus far so please no bashing.
I recently purchased my 04 Wrangler SE with around 150k miles. (high I know) I only drive it a mile or two each day to work and it barely hits 195 degrees. The other day I was sitting in a drive thru and noticed it at 210. I limped it home and it didn't overheat. I noticed a week a ago the overflow tank was empty. Being a moron, I put in a 50/50 super tech coolant mix that said "mix with any coolant". The overflow tank was caked in something that came out like green paint chips. I figure/hope since i never got up to running temp it didn't suck thru the engine, but maybe I'm just being naive. I have flushed many times with water and then with a coolant flush. It all came out clear, even the first drain, which may rule out partially the head gasket. I put a new gasket and thermostat back in and the proper coolant. If the jeep sits it will continue to go past 195 even though it seems the thermostat is working correctly. I burped the system and can see a "flow" with the cap off. Another thing I noticed is the elect. fan does not come on at all. prior to or at 210. I check the fuse under the hood and it is fine. I unplugged the fan and checked for power and found nothing. I'm not completely sure when it's supposed to come on but something doesn't seem right. I also attempted to jump to 12V and nothing. Any help would be greatly appreciated.
