We have a little 4-banger Saturn, maybe 2001 or 2003 year. She normally drives it but lately I have been driving it. The heat sucks. It takes me 25 minutes to drive to work and the air coming out the heater is still lukewarm after all that time. My truck has nice, warm air after just a couple miles.
My initial thought is that maybe the thermostat is stuck open on this car. I've heard an open thermostat allows the coolant to pass continually and not let the engine temps warm up like usual. Any way to check the thermostat without cracking open the system and having to replace the gasket and lost coolant? Any ideas on what else it could be? All the heater controls appear to be working.
