Sounds like blown head gasket.
You might as well take the motor our, its a pain in the a**. the thermostat is between the motor and the firewall and above the transmission...NOT fun. I replaced mine when I had to rebuild the motor due to a broken writs pin :(
Probably a gasket leak. Could be the intake gaskets or the thermostat gasket.
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
I have replaced thermostats before and it seems that it is located on the side of the motor where the bottom hose goes into engine what do i need to remove to get to it?
faulty thermostat, stuck fan relay, bad fan motor, no voltage to motor, bad circuit board, bad run capacitor...
I have a 2004 kia Sorento and just replaced the thermostat. Follow the bottom hose on the radiator up to the engine, remove the two bolts that hold the thermostate case to the motor (you can remove the hose from it if you want to, I was lazy and left it attached) and the thermostat is right there.
The thermostat on a 1998 Isuzu Trooper is located on the front of the motor. It is in the top radiator hose where it connects to the motor. To access the thermostat, the hose needs to be disconnected from the motor.
in motor
Either the fan motor or the sensor needs to be replaced. or your thermostat is stuck.
The larger part with the spring has to be towards the motor. A very few are oval instead of round and have to be placed correctly to fit the housing.
Weak battery or alternator output.
my jetta keeps overheating so i replaced the thermostat hoping that was the problem but know there telling me it might be the water pump check it out maybe its that
