Seal the joint between the left cylinder head and the engine block with the APEX Automobile Parts Inc AHG425L, a left-position Ford Ranger cylinder head gasket that is a direct-fit replacement for the 1991-2008 Ford Ranger, the 1986-1997 Ford Aerostar, and the 1994-1996 and 1998-2007 Mazda B3000 with the V6-3.0L engine.
A head gasket sits between the cylinder head and the block. It is designed to hold combustion pressure in the cylinders and to keep the coolant and oil passages that cross the joint separate from each other and from the outside of the engine.
Signs it may need replacing: coolant loss with no visible external leak, white exhaust smoke, overheating, coolant in the oil or oil in the coolant, or low compression on a cylinder. These symptoms can have other causes, so diagnose before you replace anything. If a failed left head gasket is the cause, the AHG425L replaces it.
Installation note: follow the vehicle service procedure for surface preparation of the head and block, bolt torque and tightening sequence. Check the service information for the correct head bolts and whether the originals may be reused.
