If you mean that the temperature gauge stays in blue area, likely the thermostat is stuck in the open position. Yes>>> change the thermostat. Ues one rated at 195 degrees and don't forget to buy a gasket and some glue to install. When re-filling coolant, fill the system as much as you can through the radiator, Start the engine and run 'till it gets very close to operating temp. Monitor cooant level and add as needed while engine is running, cap off. When close to or at operating temp, turn engine off and wait about two minutes. RE-start engine, run with heater full on and continue filling radiator slowly till it is full. Close cap, drive about 1/4 mile, top off recovery bottle and you should be finished. (while filling, sometimes coolant will back up and spill over. this is normal. keep a pan under car to catch whatever you lost so a cat or dog dosen't drink it.)Check system for leaks... especially in very cold weather, hoses will need a small amount of additional tightening after they are hot.
Good luck

Why does the heater blow hot air when I drive after its been idling for 15min and not during the idle when it reaches the 100 Temp?...(it blows cold air in idle)


Firstly, a thermostat that opens quicker will not give you better heat. Your heater core may be partially plugged causing a low flow issue. Another area to check would be the water pump impeller for corrosion or slipping on the shaft. Does the vehicle's cooling system operate well otherwise?

2001 ford winstar top radiator hose stays cold, even close to the thermostat area i can hold on to the housing after the car has ran for 30 minutes, heater blows luke warm to warm at times, but not...


Check the heater hoses for warmth at the heater core. Some designs do not use a waterflow valve, but instead always have heater core flow and use the air flaps to regulate heat.

Now there is a difference in some thermostats and the housings. Barely noticeable are the locking tabs inside the housing and on the thermostat ring. If you have this setup and the thermostat is not locked in place, you could get some bypass around the thermostat.

If you have an electric cooling fan, the Relay may be stuck, keeping the electric cooling fan running when it should not. This would overcool the engine.

Please rate my info.

1995 sc400 lexus heater will not heat just blows cold air


you may be low on coolant, if not a common tell tale sign of a faulty thermostat is the car staying on the cold indictaor for a very long period of time especially after acceleration., some other issues may be a clogged heater core, however the most likely culprit is low anti freeze or a malfunctioning thermostat.

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

Heat dont work but blows cold air


There is a little list you can check. Low on anti-freeze, climate control doors not switching to the heated position, or clog heater core, even a bad thermostat. You will definetly find your problem in that area.

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.
