I have a 2003 Buick century. I have replaced the head gaskets, radiator, cooling fans, thermostat,water pump, and heater core. The temperature gauge keeps going up and down and the heat comes and goes. What is the problem with my car?
My car has 124000 miles.
My car has an automatic transmission.
This is usually caused by air pockets in the system. Purge air from the cooling system and see if this fixes the problem. You may have a slipping serpentine belt and should check it for slipping.
