heater core? are there two coolant lines going into the fire wall?
Not neccesarily, The thermostat just went out in my girlfriends 97 Eclipse. If you sat and let it idle, it would reach normal operating temp. As soon as you started driving, it would cool way off and blow cold air.brianeclipse98 said:if the thermostat was screwed wouldnt the car overheat? it warms up just like it should and stays there. is there a way its still messed up?
