Does it have 2 lines coming from the top of the oil filter, and going to the radiator. If so that is the oil cooler. You need to replace the RADIATOR Those 2 lines go into the radiator so it can cool the oil, and the tubes are leaking oil into the coolant.
The engine block coolant drain plug on a 350 Chevy Tahoe is above the oil pan, mid engine on driver's side
That means the engine is running HOT. Need to check the coolant level and check for coolant leaks.
The coolant capacity for the 2002 Chevy Tahoe is approximately 16 quarts. The coolant can be purchased at any auto parts store.
per the Chevy service department it does not!! hope it helps.
