I have a 2000 Cavalier. It has been overheating, we replaced the thermostat, the fan motor, and radiator hoses. It kept smelling like antifreeze burning. It died, had to have it towed, and it does not start at all. There is alot of spark, just won''t turn over. So, I am thinking it is the head gasket...have everything dissasembled, down to the head gasket. Am I sure this is the problem? Do you have suggestions? I thought possibly the water pump as well.
Optional Information: 2000 Chevrolet Cavalier 2.2Already Tried: replaced radiator hoses, thermostat, fan motor. Still leaking antifreeze. Won't start
If the engine were together you could pressure test the cooling system looking for any external leaks. If that were inconclusive you could then do what's called a block test. Run the engine up to operating temp. and then "sniff" the vapors from the radiator looking for signs of compression or combustion gases in the coolant (indicative of head gasket or cylinder head warpage/failure). You can get these block testers from your local autoparts stores and what happens is the test fluid turns from a dark blue to a light green if positive for these vapors in the coolant.
