Help keep combustion pressure, coolant and oil where they belong with the APEX Automobile Parts Inc Cylinder Head Gasket AHG359L, a left-side head gasket for the V6-3.8L engine. It fits many vehicles, among them the 2000-2005 Chevrolet Impala, 2005-2009 Buick Lacrosse and 1995-2002 Chevrolet Camaro. See the Buyer's Guide tab for the full list.
A head gasket sits between the cylinder head and the engine block. It seals the combustion chambers so cylinder pressure stays contained. It also keeps the coolant and oil passages that run between the block and head separated from each other and from the outside of the engine.
- Position: left side.
- Engine: V6-3.8L on every listed application.
- Quantity per application: 1. The listed applications use one gasket in this position.

Signs a head gasket may need replacing include unexplained coolant loss, overheating, white exhaust smoke, milky oil, and oil or coolant seepage at the head-to-block joint. These signs can have other causes, so diagnose the engine before replacing the gasket.
Head gasket replacement is a major job. Follow the vehicle service information for surface preparation, the torque sequence and specifications, the correct head bolts, and whether the original bolts may be reused.
