There is an engine temperature sensor that operates the cooling fan.
you may need new water pump the cooling fins wear out a common cause.
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.
The thermostat may need to be replaced. The cooling fan might not be working. The cooling fan should run while the a/c is on. Two things I would check first.
my guess is the thermostat if you just replaced the thermostat then it might be an air pocket in the cooling system solved by taking the cap off the overflow tank squeezing the radiator hose going to the thermostat housing until the water pressure opens the hose in your hand this forces your thermostat open. if you decide to replace the thermostat yourself do the same as above to make sure all air is out of your cooling system.
Yes, a thermostat opens and closes in response to the temperature in the cooling system under normal conditions. If it is sticking it can cause fluctuations in the radiator coolant temperature.
Even though you have already replaced the thermostat, there are other issues that can cause your Nissan Maxima to overheat. Your fan may be stuck and not operating as it should.
yes sometimes cause if it fails open the temp sensor will kick the light on tellin its too cold or opposite if the thermostat fails closed
If the electric cooling fan(s) are not coming on that may be the problem.
If your doing a lot of city driving you should get it fixed... the thermostat tells the cars computer when to turn on the fan which provides more the 50% of your engine's cooling in city driving!
Low of coolant, defective water pump, clogged radiator interior or exterior, cooling fans not working, thermostat installed up side down, or you may have bought a bad, new, thermostat. It happens. Also running 100% water will cause it to overheat. Run a 50/50 mix.
no if the pump is leaking it is bad and nedds replacing
More than likely it needs a new thermostat and the radiator back flushed.
You can remove the thermostat, but you son't want to. That will cause the computer to think that the car has never heated up properly and make it run as if it needs to heat up. This will affect fuel economy, power, and longetivity of the engine. You will be better off fixing your cooling system wherever the problem is. DO NOT REMOVE THERMOSTAT!!!!!!!!!!! the Computer will run in Limp Home Mode forever until its replaced, really bad economy,Worse Performace,will run the cooling fan constantly.
Possible reasons for overheating: Low or out of coolant Clog in cooling system Thermostat failure Cooling fan not operating water pump failure
clogged radiator, advanced timing, worn water pump, dragging brakes, etc. Usually, the thermostat isn't the real cause of overheating.
A lack of water in your cooling system will cause your 2002 Pontiac Sunfire to overheat. A malfunctioning thermostat can also cause it to overheat.
Blocked radiator, low on coolant, stuck thermostat, air in cooling system
The engine cooling fans are not functioning, low on coolant, bad thermostat,
most probably cause would be your cooling systme is not bled properly and air is in your system or your cooling fans and or thermostat are not working properly.
No, The thermostat just causes the cooling water to get to operating temperature faster. It restricts coolant flow to the radiator until it opens. However, if you replaced the coolant with plain water when this was removed, that could have caused the problem. Plain tap water in an engine, especially one with an aluminum block, may cause a chemical reaction and cause internal damage. Antifreeze helps to prevent this and provides lubrication to the water pump.
My 94 escort was doing the same thing. I replaced the throttle valve assembly and that seems to have done the trick. Hopefully that helps you out.
It is possible. A more likely cause is the gas cap was replaced incorrectly or left off after getting gas
There are a bunch of things that can cause that. Water pump, thermostat, switch not engaging the heater, air in the heater core, not enough antifreeze in the cooling system. do i need a new thermostat
