Common Problems This Part Can Address

• Oil leaks from a cracked, rusted, or damaged pan
• Stripped or worn drain plug threads
• Oil seepage around the pan sealing surface
• Damage from road debris or corrosion
• Poor oil control from a worn or missing baffled pan

Installation Notes

Before installation, verify engine application and confirm whether your vehicle uses an oil level sensor, since several listed fitments are for vehicles without that sensor. This oil pan does not include a gasket or seal, so the sealing components must be sourced separately. Clean the mating surfaces thoroughly, inspect the drain plug threads, and torque fasteners evenly to help prevent leaks.

Quality Assurance

Dorman manufactures this oil pan as a precision-matched replacement for the original equipment design on the listed applications. The steel construction, OE-style dimensions, and application-specific fitment support reliable service on compatible Buick LeSabre, Chevrolet Lumina APV, and Pontiac Trans Sport models. Part Number 264-147 is intended to restore proper oil containment on the specified vehicles.
