Most recently I have noticed my temperature gauge rising and im hearing bubbling in the overflow jug. I opened the hood and took off the radiator cap and all the fluid was it drained from the radiator but then it started filling back up.
I am wondering if it is my head gasket or my water pump.
I drove it this morning to work and when I got to work I opened the hood and the radiator was warm to the touch but there was no fluid on the ground. the overflow was about 1/2 full. so can you tell him if it is the water pump or the head gasket. It is not blowing smoke. I do let it warm up before taking off in the cold weather.
It is a 2002 Buick Lesabre 6 cylinder.
Could it be the blower motor for the cooling system
