There is an engine temperature sensor that operates the cooling fan.
No
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.
If the electric cooling fan(s) are not coming on that may be the problem.
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.
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 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!
