Keep combustion pressure, coolant and oil where they belong with the APEX Automobile Parts Inc Cylinder Head Gasket, part number AHG374. It is a direct-fit replacement for the 2004-2005 Chevrolet Aveo with the L4-1.6L engine.
A head gasket sits between the cylinder head and the engine block. It is designed to seal the combustion chambers and to keep the coolant and oil passages that run through that joint separate from one another.
Signs this part may need replacing: coolant loss with no visible external leak, white exhaust smoke, engine overheating, milky or contaminated oil, bubbles in the coolant reservoir, or low compression and misfires. These symptoms can have other causes, so diagnose the engine before replacing the gasket.
Installation note: Consult the vehicle service information for surface preparation, the tightening sequence and torque values. It also lists the correct cylinder head fasteners and whether they may be reused.
