MAHLE 1178BS cylinder head gasket for the 1988-1999 Chevrolet C1500 V8 5.7L and other vehicles seals the joint between each cylinder head and the engine block. It keeps combustion pressure, coolant and oil in their own passages.
Coolant loss with no visible leak, milky oil or overheating can mean a cylinder head gasket is leaking. Those symptoms also have other possible sources, so find the cause before replacing the gasket. With the engine off and cool, check the coolant level and look under the oil filler cap for milky residue. A shop can run a compression or combustion-gas test to confirm.
The 1988-1999 Chevrolet K1500 V8 5.7L and the 1995-2000 Chevrolet Tahoe V8 5.7L are among the Chevrolet, GMC and Pontiac models it fits. This listing is one gasket, and both of these take two, so order two and fit them together.
