Well it seems like every morning now, I will start my car, and start driving temps will get up to around 170*(mind you I have a 180* T-stat), if I get on it, the temp will peg cold, and the high speed fans will kick on, it only started once it got to around 50* outside. The problem is the high speed fans will kick on, the engine is so cold I can't even really feel the heat off of it, or the hose, and the fans will stay on even after I shut the car off. It seems like it goes into a safe mode of some sort. It's really beginning to piss me off, then if I sit still with the engine idling the temp will spring up out of nowhere back up to normal temps. Can someone tell me what is happening, I think that since it's cold out, and I have the 180* t-stat that when I get up to temps with the 185* fan turn on from the DHP, the engine gets colder than what it should be due to outside cold cooling the radiator, the PCM senses that and thinks the temp sensor isnt reading right and goes into safe mode turning the high speed fans on. What should I do?
