I have a 2003 Oldsmobile Silhouette and it keeps over heating first problem was it had a hole in a hose so changed it that caused the serpentine belt to snap changed that also took thermostat out for few days didn't stop so replaced with a new one then changed my water pump and I'm still over heating and now it acts like it dont want to start takes forever to start and looses power when I slow down and is still overheating
Changed my thermostat changed my water pump and new serpentine belt and
still overheating??? So today were going to change the alternator, but need
more information on if I'm right or wrong
the first thing to check is if the fans come on when it gets hot , then the thermostat , but I'll bet a beer you have a blown head gasket , look under the oil fill cap what do you see ? what does the exhaust look like ? I drink sammy adams
It's normal I think and if it was the heads wouldn't it be knocking
Picture
i have the same problem, the fans work, the water circulates, changed the pump, changed the gauge and thermostat one fan is a little lower then the other but both work and flushed our coolant and replaced and still runs really hot.
I had overheating problem also, finally figured out the catalytic converter was so clogged it was causing a back pressure which would not allow the heat of the engine exhaust to exit through the muffler. I loosened the two nuts holding the exhaust pipe to the manifold creating an exhaust leak to test, the overheating stopped and the van ran with much more power, So I replaced catalytic converter. This also solved my a/c not cooling correctly by lowering the engine compartment temperature
