Keep combustion pressure, coolant, and oil where they belong with a fresh Nissan Altima head gasket: the APEX Automobile Parts Inc Cylinder Head Gasket AHG519. It is a direct-fit replacement for the listed application, the 1993-2001 Nissan Altima with the L4-2.4L engine.
A cylinder head gasket sits between the cylinder head and the engine block. It seals the combustion chambers and keeps the coolant and oil passages that run between the two separated. The listed application uses one gasket per engine.
Signs this part may need replacing: unexplained coolant loss, white exhaust smoke, milky oil, bubbles in the cooling system, overheating, or low compression in adjacent cylinders. Other faults can cause these symptoms, so diagnose the engine before replacing the gasket. If overheating caused the failure, address that first.
Installation note: Consult the vehicle service information for the correct head bolts, the torque procedure, and whether the original fasteners may be reused. Inspect the cylinder head and block sealing surfaces as the service procedure directs.
