Question about 1999 Chevrolet Malibu
There could be a lot of air bubbles in the coolant.
The oil can turn a chocolate milk color ( could also happen with a bad lower intake gasket on the V-6).
You could see white smoke coming out of the exhaust.
The engine could develop a misfire do to lack of compression or coolant contamination.
There may be an external oil or coolant leak.
There are a couple of test to check to see if there are hydrocarbons in the cooling system. One is to use a four gas analyzer to sniff the coolant. The other is the bulb style with the blue liquid. Seem from the radiator is pumped through a fluid and if the fluid changes from blue to green there are hydrocarbons (exhaust) in the cooling system.
