Thermostat Heat

I recently saw someone that had a 2002 Galant that had no heat. I also have this type vehicle. I too have no heat. I have replaced my theromstat and kept the coolant full. Sometimes I get heat, usually I do not. Since I have replaced the theromstat, the problem seems worse. Can you tell me what else could be the problem? miles is 44,000.

Without knowing your car, check the thermostat housing. Does it have a screw or nut on top of it? If so, that is a bleeder and you need to bleed the air out of the system until coolant only comes out of the bleeder.

Galant 2002 Theromostat

Thanks for the info. No, there is no air bleeder on the thermostat housing. I have had to add coolant a few times (reserve bottle was empty) and I had not thought that I lost that much fluid when I replaced the thermostst. I cannot find any leaks but the coolant has run low twice since I did the repair (5 days ago). Not sure where the coolant is going! The heater coil does not appear to be leaking nor does my water pump. Any ideas?

Wink no heat

Take your hands and grab the hoses going into the firewall where your heater core is while the engine is hot. Both hoses should be hot, if not you have a clogged heater core or leak. Is your floor all wet inside under the carpet on that side or does your windshield fog up? Also sometimes there is a valve on that hose leading into the heater core. Rig it wide open and check again. Also a radiator needs to have fliuid in it in order for heat. Make sure your radiator is full. If you accidently put in a thermostat upside down you probably would have over heated. Listen as you move the levels or controls of the heat. Can you hear the vacuum and doors opening and closing?

Check your oil dip stick. If the oil is unusually high, and/or if there is foam on the dip stick, you may have a bad head gasket. Also look for white smoke coming out of the tailpipe. That is also a sign of a bad head gasket.
