1999 Oldsmobile Cutlass Q&A
1999 Oldsmobile Cutlass Question: overheating?
I just got a 99 cutlass. It has 150,000 miles on it. The temperature gague shows it going almost, but not in, the red. The thermostat was replaced, the coolant system was flushed, and the mechanic said the pressure test didn't show anything, but it still looks like it is running hot. Any ideas? - jouna
Check the radiator and the radiator fan operation. Have the shop use an infrared temperature gun to determine that the engine is actually running hot, it could be a gauge or sensor problem too. Good Luck, let us know what they end up finding out! - lawrenceg
I agree with Laurenceg. I would also ask a shop to check that the radiator is not internally restricted, check that the cooling fan is operating correctly and do a "block check" (which is a chemical check to test for the presence of carbon monoxide in the cooling system which would only be present in the case of a blown or slightly blown head gasket). Would love to know what turns out to be the problem. - patrick mannion
check to make sure the fans on the radiator are working. they should kick on once it heats up. mine just went out and i'm trying to figure out whats wrong - rigga
check the radiator for blockage or debris. always a good thing to do. i also have a 1999 cutlass. had same problem. so i would go with patricks theory on this issue and get the head gaskets checked. cuz mine blew out and was fortunate to not have coolant get in to the oil. - Visitor
I got my car a year ago and as soon as I got it I found out the lower intake gasket was bad and I had it replaced. Recently after having it fixed my car started blowing steam from the right side an...
I have replaced the coolant temperature sensor. The cooling fans do not come on. Have checked all fuses and relays related to the cooling fans. Have disconnected the temperature sensor while car ru...
The heater core may leak coolant which could cause the engine to overheat and steam to fog up the inside of the windshield.
A coolant leak may develop from the water pump. The engine may overheat as a result of the coolant loss. A leaking water pump should be replaced.
