    Thanks. I just looked where the thermostat is on this model... UUUGGGHHHHH!!!!!! May be cheap but won't be easy. Where is the bypass located? I'd like to check that before pulling it apart.

Heater not blowing hot air


Hi Chris, sounds like your thermostat may be worn and not closing all the way which would cause your engine to run cool at times. If you have a temp gage it should tell you if the engine is actually warming up or not. If not I would replace the thermostat.

I have a 2002 Chevy tracker. It's been running hot on the temp gage. So, I have changed the thermostat and replaced the radiator hose because of corrosion but it still overheats and when I turn on


If there is cold air coming out the heater than there is air in the system. After you replaced the thermostat did you run the engine at idle with the radiator cap off until the engine came up to operating temp? Doing this will purge the air from the system.

Sounds as if the engine is not building up temp due to cooling system working. If engine temp gage is reading low try covering 1/3 of radiator with a piece of cardboard "Bumper side" to reduce the cooling effect.. just watch temp and out side temps if warming up outside or heavy driving remove the blocking to allow full cooling

I have a 1993 Acura Ledgend. For some reason my heater does not continue to blow hot air, it does for a few minutes and then begain to blow cold air. It does this often now. It works and then it blows cold...


first check to see that you coolant level is full, check it after the engine has cooled down,so there is no pressure in the system. otherwise you possibly have a head gasket in the early stage of failure

Temperature gauge fluctuates and the heater blows cold air


Definitely check your fluid level in your radiator. Top it off all the way. I've seen that happen multiple times on cars that were low on anti-freeze. If that doesn't work try replacing your thermostat. It's cheap and the easiest place to start if topping off the fluid doesn't get you fixed up.

No Heat in 99 Taurus


Just finished fixing my daughters 1999 taurus heat. It would blow warm only when running down the road. At idle it blew cold. I started with replacing thermostat, and water pump because they are the easier fix. Still did not help. Then I replaced the heater core. A daunting job but not that hard to move the dash slighly out of the way to replace. There is a good write up at tarusclub.com. After that, heat was better but at idle, it would still blow cool sometimes. Researched and found answer. Park car on the steepest hill you can find with front of car up. Start car and take off reservoir cap. Let car warm up and keep rpms about 1500. After a while the fluid will come running out of the car and all over the place but it will bring air bubbles with it. Reduce rpm, add more fluid and repeat about 3 times. It will make a mess but after that, the heater works perfectly. We get heat long before the temp gage indicates any and it never blows cold unless you lower the temp.
