Clean the oil pan and engine sealing surfaces thoroughly before installation. Verify the oil pan flange style, bolt-hole count, and gasket profile against the vehicle application before assembly. On Pontiac Grand Am, LeMans, Bonneville, Catalina, Firebird, Grand Prix, GTO, Laurentian, Parisienne, and Tempest models, confirm the 3-hole rear oil pan flange noted in the fitment data. Follow the service manual for torque sequence and tightening specifications to help maintain an even seal.
