Seal the joint between the cylinder head and the engine block with the APEX Automobile Parts Inc cylinder head gasket, part number AHG270, designed to hold combustion pressure inside the cylinders and keep the coolant and oil passages separate. It fits many Jeep models with the L6-4.0L engine, among them the 1997-2003 Jeep Wrangler, 1993-2003 Jeep Grand Cherokee and 1987-2001 Jeep Cherokee. See the Buyer's Guide tab for the full list.
The head gasket is clamped between the block deck and the cylinder head, where it faces combustion heat and pressure along with coolant and oil flow. Signs it may need replacing include coolant loss with no external leak, overheating, white exhaust smoke and milky engine oil. If a failed head gasket is the cause of these symptoms, this part replaces it. Other faults can cause the same signs, so diagnose the cause before you replace it.
Installation requires removing the cylinder head. Follow the vehicle service information for the correct head bolts, tightening sequence and torque, and for whether the original fasteners may be reused.
