    Yes but no but you can tell that that car isnt as warm as it was when its idol. it take about 15 to 25 minutes depending on how cold it is outside to warm up. Once you have been driving for a while you notice that the temperture gage goes to "C". It stay there until while the car is driving the once the car is idol again the temperture gage starts to tick back up to normal. The heat continue to blow but it not a powerful blow. I dont know the sound for a radiator fan.

    I have a 1996 eclipse when the car is sitting and warming up it is very hot but when I start driving the gauge will drop to C and it will start cooling off and you can feel the car getting cold.

    I take it when gauge goes back to "C" your are satisfied with temperature of heat in the vehicle? With that said, you need to check & see if radiator fan is going on & off when it should. Do you hear it come on & off when you let it sit & idle, when gauge is up warmer?

First of all, it doesn't sound like your thermostat is working correctly to keep good hot/warm air coming , so I would change that, or have it changed for better heating inside. If you lift the hood & look in front of your radiator, On the engine side, you'll see a fan attached to, or in front of the radiator. It won't come on until the coolant temperature gauge gets up to proper operating temperature. Without getting in to too much detail, have your thermostat changed, and my guess is everything else will start working as it should, and whoever does the work, should know enough to check the fan operation when they do the thermostat.

My 2007 Chevy HHR 2.2L, coolant temp sensor is reading that the coolant temp is 20 degrees warmer than the outside temp after sitting for over 12 hours and the operating temp gets to 214 degrees without...


Sure the engine coolant will be warmer than the outside temperture and if the car has been sitting a long time in cold weather and the outside temperture warms up it could be the other way around. The coolant temperture sensers aren't real accurate as they are a relaitive senser beween hot and cold and the numbers reported don't have to be real just the change from hot to cold and the reching of the coolant to the operating temperture. Noe it the senser doesn't read the opertating temperture coprrectly you'll have all kinds of problems. The therostaste will try to set the temperture of the water to it's set temperture and can open or close completly to get 195 degrees F. Many times if it's too cold then the stat is bad and needs to be replaced This shows up in alot of cars first thing after winter and the first onset of cold weather when the daily tempertures vary the most from day to night.

Good Afternoon, Why is my temperture gage staying at C? Also my heater is not heating lke it should. when I stop at a light it blows cold air. can someone please tell me what could be wrong?


It could be your thermostat. If it is stuck open and you are driving in cold temperatures your car will not warm up properly. As for your heater, it shares the coolant from inside the engine and radiator so if your engine isn't warming up it won't warm up either.

1998 Tercel Cold heat to the windshield. Lukewarm out front vent.


Hey,

I just replaced my thermostat in my car due to the same problem. Except mine was a 92. I figured I'd start with the thermostat and antifreeze. Then the heating core. Now I have heat.

But yet I still have no heat on the windshield.

TEMPEATURE GAGE READS HOT WHEN AT AN IDOL BUT MOTOR


If cooling fan works, it maybe a sticking thermostat not opening fully. Check that cooling system is full (check cold) first. Then if that seems ok, i would replace the thermostat.

Replace the thermostat, if that does not cure the issue you have a slight head gasket leak. I am a retired Ford dealer tech and this is what I have found causes this issue.

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.
