Certainly. If the engine coolant is flowing freely into the radiator, it will remain quite cool and the coolant that circulates into the heater core will never warm up. The thermostat blocks the coolant from entering into the radiator if the temperature is below the set level on the thermostat. Usually 185, or 195 degrees F. Engines don't run as efficiently at the lower temperature either, so if the thermostat isn't working right, replace it.

Thermostat stuck open. Replace! A low coolant level will also cause this problem. The blend door could be stuck also.

Heater core is stopped up or thermostat is stuck open.

clogged radiator, advanced timing, worn water pump, dragging brakes, etc. Usually, the thermostat isn't the real cause of overheating.

Generally, the cause is a thermostat that is stuck open. A good way to test is to turn the heater control to off for a few minutes, then turn on and see if you have heat. If you do, you need a new thermostat.

no heat could be a number of things, you could have a bad thermostat or a crack in the block. or even just a bubble in one of the lines, (coolant) better hope its the thermostat

Yes, with out the thermostat, the coolant can circulate to fast to effectively absorb and transfer any heat. Updated answer, The thermostat is to keep the engine running at a factory set predetermined temperature, without the thermostat the engine should run cooler.

if the thermostate is stuck open it wont allow the coolant to reach a certain temp. which could cause the heat to not work to well.

Yes, and it can also make your car to over heat

Did you put the thermostat in backwards? I would check to see where the steam is coming from. I had to change out small hoses for the same problem with mine.

Sticking thermostat could cause this. If the thermostat is stuck open, it never gives the engine a chance to fully heat the coolant. Follow the top radiator hose to the engine, remove the hose and remove what it hooks to and there's your thermostat.

IT COULD BE THE THERMOSTAT, THE VEHICLE BEING LOW ON COOLANT, OR A MODE DOOR WITHIN THE DASH

Could be low on coolant, a stuck open thermostat or a partially blocked heater core.

the thermostat stuck shut. will cause the car to over heat at ant temp!

Yes! Thermostat stuck open. Replace thermostat. It could, but the thermostat is normally open when the engine is warm so you should only notice this when the engine is cold or warming up.

Thermostat, or fan motor if it does not blow hard.

Yes it could and so could a stuck open thermostat or a plugged heater core or a faulty temperature blend door actuator.

could be a sticking thermostat.

If it's interior heat you are talking about, it could be the thermostat. If you find your temp gauge is fluctuating all over the place, change the thermostat. If not, it could be your heater core. You could try flushing it out.

Yes. Check that first. If you are not getting heat then it could also be a stuck thermostat.

It could cause the check engine light to come on with a code concerning cooling system/thermostat performance.It could cause the check engine light to come on with a code concerning cooling system/thermostat performance.

If it is stuck open, the answer is yes. When in doubt, just replace it.
