Detailed Product Description
The Dorman 264-129 engine oil pan is engineered from steel to withstand the rigors of engine operation while providing a secure reservoir for engine oil. Its baffled design helps minimize oil movement during acceleration, braking, and cornering, ensuring consistent oil supply to the engine. The rear sump location and wet sump configuration are tailored to fit specific GM vehicles, including Buick, Oldsmobile, and Pontiac models such as the Bonneville and Grand Am. The included drain plug with a 1/2x20 thread size facilitates routine oil changes without additional parts. Although this oil pan does not include a crankshaft wiper, dipstick port, or pickup, it meets the essential requirements for a direct replacement oil pan in compatible vehicles.
