i have 2001 pontiac aztek. i have replaced the thermostat, water pump & now the radiator. since i have replaced the radiator the car is running even hotter. what could be causing this?
Its very common for head gaskets to go bad on this engine and cause over heating so I would have that tested, this is assuming you bled the air out of the system and the fan is working?
the head gasket is fine, we have already checked that. this has been happening for a little over a year
How did you check the head gasket? Is the fan working? Did you bleed the air out of the system?
