Seal combustion pressure where the cylinder head meets the block with the APEX Automobile Parts Inc Cylinder Head Gasket, part number AHG1134R, cataloged for the right-side position. It fits many vehicles, among them the 2004-2010 Ford F-150 4.6L / 5.4L, 2006-2010 Ford Explorer 4.6L and 2005-2014 Ford Expedition 5.4L. It is a direct-fit replacement for the listed applications, which use the V8-4.6L or V8-5.4L engine. See the "Vehicles it fits" section for the full list.
- Position: right side.
- Engines: listed V8-4.6L and V8-5.4L applications.
- Quantity per application: the listed applications use one.
- Function: seals the joint between the cylinder head and the engine block.
The head gasket is clamped between the head and the block. It is designed to hold combustion pressure inside the cylinders and to keep coolant and oil passages separate from each other. Signs a head gasket may need replacing include coolant loss with no visible leak, overheating, white exhaust smoke, milky engine oil, or bubbles in the coolant reservoir. Other faults can cause these same symptoms, so diagnose the cause before replacing. If a failed right-side head gasket is the cause, AHG1134R replaces it.
Installation: Clean and inspect the head and block mating surfaces as the service procedure directs. Consult the vehicle service information for the correct head bolts, torque sequence and whether fasteners may be reused.
