this is my brother in laws car, he has hanged the water pump, the themostat, and the car steal overheats though the reservor when the motor runs for a while.

if you turn the heater on it gets really warm but doesnt get to 225 degrees.

could it be the radiator or the cap or a sensor.

please let me know. thanks.

Hi there,

Have the radiator cleaned & flow tested and check the pressure cap as well. start here.
