Question about 1999 Oldsmobile Alero

1 Answer

I have been having problems with my car leaking and overheating for some months now. I first replaced my thermostat, which worked for awhile. Then once the problem resumed, I changed my upper radiator hose. But that has not worked either. A few mechanics told me it was my intake manifold gasket. So I took it to a mechanic told him what the problem was, and he gave me a good deal. After he took everything apart, he said my intake was good, but i had a bad head gasket, so he replaced both the intake and head gasket. After he put everything together, and takes it for a test drive, my car still leaks. Does anyone know what other problems it could be? The mechanic is gonna put a pressure tester on it to see where the leak is coming from

The coolant must operate under pressure to raise its boiling point (so it won't turn to steam.)

Replace the radiator cap with a new one.

Sounds like a leaking head gasket. The gasket may have been damaged when the engine ran hot the first time.
You should not need to add coolant, so it has to be going somewhere.

Sounds like a leaking head gasket. The head gasket can allow coolant to leak into the cylinders, and compression to leak into the cooling system.

Stopleak can work. But if the mechanic that installed the parts were to use a Radiator pressure tester, he would easily find the leak and fix it correctly. If this leaks after he worked on it, he still has work to finish.

2.3l ranger keeps overheating, been through two radiators already.


Hello Ranger Joe, eight months and two radiators is very uncommon. Question, Have you visually confirmed the leak in the radiators or is the leak near the hose connections? Replacing the radiator, cap, water pump, & the thermostat leaves only two others, the hoses and the engine block/heads. Far fitched will be something or somebody poking holes in the radiator.
