ask your service station to do a compression test. I had the same problem and replaced all sensors and thermostat but after the test it was found out that there was a crack in the housing holding the thermostat
your thermostat in the cooling system is probably stuck open, you will need to replace your thermostat
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!
Possibilities: Cooling fan not working. Low on coolant. Clogged radiator, radiator hose or block.
Wouldn't be your thermostat, its going to be the fan motor for your cooling system. Because the wind that hits the motor while driving cools the motor but when you come to a stop and idle there isn't anything to cool the motor
thermostat needs replaced
Water Pump or Thermostat. May have to change water pump to replace thermostat.
If the temperature gauge is reading below normal operating temp after driving a little while it may be that your thermostat is stuck open. I replaced my thermostat and it fixed mine.
depends on what temperature thermostat was put in. come in different temperature ratings.AnswerIf you installed the correct OEM thermostat, and did not install it upside down, then no, this is not normal. You should flush the entire system, check the water pump for proper operation, clean the radiator external fins, check the operation of the electric cooling fan, (If Equipped), and make sure you bleed the system to remove any trapped air.
Check the cooling system, and I mean everything. Thermostat, temperature sesnor(s), radiator clogs, radiator cap, badly damaged water pump, belts, you could simply need to add more antifreeze. If it isn't your coolant system, then it's your driving habbits or driving conditions, in which case you may want to slow down, get a car that can handle harsh driving, or upgrade your radiator. Also check that your electric fan is coming on.
Check your electric cooling fan
Make sure you have enough coolant, but if that's not it, check the water pump.
you should have your cooling fan checked or temp sensor or relay or check your coolant it might be low or thermostat might be no good it should be one of these
