coolant fans stay on cons
95 lt1"service engine soon lights comes on and stays on until you turn the car off. the. coolant fans also come on and stay on the whole time. If I can get the service engine soon light to go off the fans stay off and won't come on at all. I have to lt car idle for 10 minutes before its a little warm. since the fans come on when you turn the engine over.
