Help keep engine oil inside the engine with the MAHLE Oil Pan Gasket OS32243, a molded rubber gasket designed to seal the joint between the oil pan and the engine. It fits many vehicles, among them the 2006-2011 Buick Lucerne and 2006-2011 Cadillac DTS with the V8-4.6L, and the 1995-1999 Oldsmobile Aurora with the V8-4.0L. It is a direct-fit replacement for the listed applications; see the "Vehicles it fits" section for the full list.
The oil pan holds the engine's oil supply, and this gasket forms the seal where the pan meets the engine. When an engine oil pan gasket starts to leak, signs may include oil seeping or dripping at the pan edge, fresh oil spots where the vehicle is parked, or an oil level that drops between changes. Other nearby seals can leak too, so confirm the source before replacing the gasket. If a leaking pan gasket is the cause, this part replaces it.
Follow the vehicle service information for surface preparation, any sealant the procedure calls for, bolt torque, and the correct fasteners and whether they may be reused. Country of origin: United States.
