Symtoms of faulty thermostat water


Before answering that, the thermostat keeps the water in the engine until a specified temp inside the engine normaly around 190 degrees..then opens up to cool through the Collins system and allows hot water to the heater core inside the vehicle....Two major symptoms are engine over heating number one..Cold weather engine is hot but no or very little warmth of the radiator hoses with no heat to heater core inside the car..Not an exoensuve part or a hard job,,most are located at the bottom of the top hose where it connects to tne top of the engine..good luck

Heater taking long time to produce any heat.


Bad news ,nothiong worse than a cold car so iam assuming this is a 16v job and the thermostat is behind the timing belt which is a summers day type job ,so as a temporary fix put a sheet of cardboard in front of the rad till the weather warms up this will make the engine run hotter and the cars internel heater radiator will be all the cooling it needs in the cold weather

2005 jeep liberty blows cold air through the heater.


could be the thermostat if it was just stating to go bad,could also be a vacume problem not letting the door for the ac/heat close all the way for a few min.and if its really cold out like below 35,then its going to take longer to warm up,my jeep takes like around 20 min at idle to warm up.yours could be a case of over cooling in cold weather too ie(electric fans on before it warms up)that would be the thermostatic sensor.

On my 2004 Grand Prix, my car has to be running for at least 45 minutes for some heat to work.The yellow light by the heater blinks while the blower comes on and goes off repeatedly until the light is...


It is possible that your thermostat is stuck open. Normally, the thermostat remains closed when starting cold, confining coolant to the engine block and cylinder head until it heats up. Once the coolant in the block is warm (usually within 10 minutes), the thermostat begins to open and let coolant flow into the radiator to cool it down some. A properly operating thermostat will continue to cycle until the coolant reaches the operating temperature of the thermostat--usually around 180 deg F. Then the thermostat will continue to adjust its opening to maintain that temp.

Thermostats can get stuck in both closed and open positions. When stuck closed, the engine will quickly overheat. When stuck open, the engine will take forever to warm up--especially in cold weather because the coolant is continually pushed into the radiator and cooled off before it ever has a chance to get warm. Changing the inexpensive thermostat may help correct your condition.

My 2005 Ford Escape will not warm up. No matter how long/far I drive the temp, guage reads cold and the air that blows out is cold as well. Any ideas about the possible problem?


You could have a thermostat that has stuck open. Try changing it, advise, use a fail safe one, if you find there is not coolant in the block when you go to change the thermostat, there is the problem rather than the thermostat, however, change it anyway Good Luck

did you install correct temperature thermostat? also is the temp guage in the car working and what does it read, if it reads a normal reading then the fan may be working improperly.

Why my heater in 2000 plymouth breeze only gives a little heat? Could it be a hose ? I know it's not the thermostat,the blowers ar working. I am wonding if theres some hoses that could be leaking?I don't...


it could be the cold air blend door or the thermostat is the engine temp up to the middle of the gauge or close to it if so then thermostat is ok if not then go ahead and replace it.

My 1996 jeep grand cherokee is blowing cold air for the first 30 minutes of my ride home (20-degree weather), then warms up slightly but never gets hot -- i'm guessing heater core (it has 200k+ miles)


It is most likely a thermostat. As your car gets older the thermostat begins to lose its spring like properties and stays open all the time causing your car to never warm up.

If you can't tackle right away, start your car in the morning and let it run for about 15 minutes to warm up. Be sure to turn the heat on full blast and recirculate the air.

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.
