So my car uns at about 75% of the temp gauge most of the time somrtimes 50%. And i noticed that my fans dont runs while the car is running but as soon as i turn the key off or on acc they run for a few minutes or until it at about 45%. what could cause this faulty wiring? How can i fix this.....Thanks ion advance

 

i would guess that either.. your thermostat is stuck closed (next time its up hot like that, get out and pop the hood and grab the top rad hose and squeeze it *it will be hot* and if its rock hard then your thermostat is closed), you're low on coolant, or less likely, the relay is dead for the fans ( i say that because they usually don't come on when you're driving, expecially when its cold out)

beat me to it ... def sounds like a t-stat prob since the relays are still working while ur car turns off.

 

ill try the t stat again but i already did new fans new t stat new radiator ne temp sensor new gauge cluster new rad hoses and new water pump im stumped. but i know t stat can come defective new so its worth a try oh and i bled the system good too
