1996 Buick Skylark Q&A

1996 Buick Skylark Question: How can you tell if the head gasket is faulty?

My car overheats going even a short distance. I also have water on the floor on the drivers side which has gotten worse! Could this be from my water pump?Thermostat, water pump? Head gasket? I had the radiator flushed but didn't take care of the problem -
Answer 1
More then likely the thermostat first, and possibly the water pump if the coolant flow is bad, but if the liquid in the cooling system is water and you are getting water in the floor, you could have a heater core leaking, and the water pump is moving water to it if it is leaking. IMO -
