I have a 1994 Olds Cutlass Supreme that keeps overheating. The head gasket was replaced in the fall along with the thermostat. It seems to be loosing coolant because the heat blows out cold and the low coolant light is on frequently. Please help me. Is it the water pump?
If it's the water pump, you should be able to see it dripping just behind the pulley. The seal on the water pump is usually what goes. If there is antifreeze drips all over the front of the engine, and it drips a bit after you shut it off, it likely is the water pump.
If it runs poorly when you first start it in the morning, however, you could still have a head gasket problem. If that is the case, you will see a lot of white exhaust, which is the cylinder blowing the antifreeze out. One thing you can do is run it with the rad cap off, and see if it continues to bubble. If it does, then your head gasket is leaking. I am assuming it is a V6, so keep in mind that you have 2 head gaskets. The other oine could be gone now if it wasn't replaced.
