MAHLE Engine Cylinder Head Gasket P/N:54579A
Seal the critical joint between the cylinder head and engine block with the MAHLE Cylinder Head Gasket 54052. This head gasket contains combustion pressure and keeps the coolant and oil passages separated where the head meets the block. It's a direct-fit replacement for many vehicles, among them the 1988-1999 Chevrolet C1500 5.7L and the 1958-1969 Chevrolet Impala 4.6L / 5.3L / 5.7L. See the "Vehicles it fits" section for the full application list and engine codes (V6-5.0L, V6-5.7L, V8-4.6L, V8-4.9L, V8-5.0L, V8-5.3L, V8-5.4L, V8-5.7L).
The listed applications call for two gaskets (Quantity Per Application: 2); each package contains one, so order accordingly. If a failed head gasket is the cause of coolant-oil mixing, white exhaust smoke, overheating, or lost compression, this replaces it — diagnose the cause before installing.
