Detailed Description

Dorman 264-884 is a replacement engine oil pan designed to match the original equipment pan on specific vehicle years, makes, and models. The pan measures 13.2 inches long, 9.8 inches wide, and up to 2.4 inches deep, with a minimum depth of 1 inch. It uses a rear sump layout, a dry pump type, and does not include a gasket, seal, pickup, dipstick port, or oil level sensor port.

Use this oil pan when servicing lower-engine oil leaks on vehicles such as the Cadillac XT5, Cadillac XT6, Chevrolet Blazer, and GMC Acadia. The OE-style mounting pattern and steel construction support a straightforward replacement where the original pan has been damaged, corroded, or leaking. Part number 264-884 is also a practical match for Buick Regal Sportback and Buick LaCrosse applications listed in the fitment data.

Common Repair Reasons

• Engine oil leaking from the pan or drain area
• Corrosion or rust damage to the original pan
• Impact damage from road debris or underbody contact
• Stripped or worn mounting points
• Replacement during lower-engine service on GM vehicles

Installation Notes and Tips

Verify engine code, pan shape, and mounting-hole count before installation. Clean the sealing surface thoroughly and inspect the drain plug threads and surrounding flange for damage. Because the gasket or seal is not included, use the correct service seal specified for the vehicle. Confirm clearance around the rear sump design and check for any existing oil leaks before refilling the engine.

The part number 264-884 is built to follow the original pan configuration for dependable service on compatible Cadillac XT5, Cadillac XT6, Chevrolet Blazer, and GMC Acadia repairs.
