Seal the right-side cylinder head to the engine block with the APEX Automobile Parts Inc Cylinder Head Gasket, part number AHG877R. It fits many vehicles, among them the 2006-2015 Toyota Tacoma V6-4.0L, the 2006-2010 Toyota Tundra V6-4.0L and the 2006-2009 Toyota 4Runner V6-4.0L, and it is a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list.
A head gasket sits between the cylinder head and the block. It is designed to seal the combustion chambers and to keep the coolant and oil passages that run between the two sealed from each other and from the outside.
- Position: right side
- Engine: V6-4.0L on the listed applications
- Quantity per application: 1, so the listed applications use one gasket in this position
Signs a head gasket may need replacing include unexplained coolant loss, engine overheating, white smoke from the exhaust, coolant mixing with the oil, or misfiring. These symptoms can have other causes, so diagnose the source before replacing parts. If a failed right-side gasket is the cause, AHG877R replaces it.
Replacing a head gasket requires removing the cylinder head. Follow the vehicle service information for surface preparation, tightening sequence and torque specifications. Also consult it for the correct head fasteners and whether they may be reused.
