MAHLE 54597 left cylinder head gasket for the 2006-2016 Chevrolet Express 2500 V8 6.6L and other vehicles seals the joint between the cylinder head and the engine block. This MAHLE cylinder head gasket, also called an engine cylinder head gasket, holds combustion pressure in and keeps coolant and oil apart.
Coolant loss, white exhaust smoke or oil mixing with coolant can mean a failed head gasket. A cracked cylinder head, a warped head surface or a leaking radiator hose can be behind some of those signs too, so track down the source before you buy.
This left-side gasket is a direct-fit replacement for the 2006-2016 Chevrolet Express 3500 V8 6.6L and the 2009-2016 Chevrolet Express 4500 V8 6.6L, as well as the 2006-2016 Chevrolet Express 2500 V8 6.6L. The left side takes one, and the right side is a separate gasket ordered on its own. Open the "Vehicles it fits" section and look up your own model, year and engine.
