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.
Yes, it can.
Yes, and it can also make your car to over heat
i set my thermostat to cool, my heat pump start it go to heat but not cool, i think the thermostat. can u help.
The purpose of a thermostat on a running heat pump is to be able to determine the temperature the pump is operating at. This is used for regulating the heats needed.
it has to adjust or it's broke.
The thermostat may be stuck open
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.
Yes, it can.
Yes
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.
clogged radiator
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.
A common cause is the thermostat being stuck in an open position.
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.
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
