Question about 1996 Chevrolet Monte Carlo
I have oil in my coolant overflow tank. I am running green coolant in a car that came with dexcool orange coolant. This is a '96 monte carlo.I have within the past two years had the intake gaskets replaced, water pump, and radiator replaced. Why do I have oil in the coolant overflow tank again? Are the intake gaskets shot again?? Should these need to be replaced again this soon???
Since you are running green coolant in a car designed for dexcool that may have contributed to a leaky intake gasket and/or head gasket. dexcool was specially formulated to run in the GM vehicles because the gaskets and seals can be easily distorted when the wrong chemicals are soaking them. oil in the coolant is usually either a head gasket or the lower intake manifold leaking into the cooling system. also if the intake gaskets werent done properly that would cause oil in the coolant as well. i suggest you take your car to a reputable shop and have it tested for a headgasket leak and to have the lower intake inspected.

If there is oil inside the coolant liquid that is the head gasket.
Check first if oil can leak into the coolant tank from the cap.
Usually when you get oil into the coolant liquid you have an head gasket problem, do a compression test, or buy the home tester below.
