Help seal combustion pressure and keep coolant and oil in their own passages with the APEX Automobile Parts Inc AHG612, a Subaru Outback cylinder head gasket for the H4-2.5L engine. It is a direct-fit replacement for the listed applications, including the 2000-2009 Subaru Outback, 1999-2011 Subaru Impreza and 2000-2009 Subaru Legacy.
A head gasket sits between the cylinder head and the engine block. It seals that joint so combustion gases stay in the cylinders, and coolant and oil stay in their separate passages. When the seal breaks down, the engine can lose coolant, overheat, or let fluids cross over. If a failed head gasket is the cause, this part replaces it.
Fitment (H4-2.5L): 1999-2010 Subaru Forester · 1999-2011 Subaru Impreza · 2000-2009 Subaru Legacy · 2000-2009 Subaru Outback · 2003-2006 Subaru Baja · 2005-2006 Saab 9-2X
Signs a head gasket may need replacing include unexplained coolant loss, overheating, white exhaust smoke, milky or contaminated oil, and oil or coolant seeping at the head-to-block joint. These symptoms can also have other causes, so diagnose the engine before replacing parts. Follow the vehicle service information for surface preparation, the torque sequence, the correct head bolts, and whether the original bolts may be reused.
