What It Helps Fix

• Oil leaks from a cracked, rusted, or damaged oil pan
• Oil seepage around the drain area or mounting flange
• Poor oil retention caused by a warped or dented pan
• Service issues when the original pan no longer seals correctly
• Replacement needs after impact damage to the underside of the engine

Installation Notes and Tips

Verify the rear sump layout, mounting hole count, and dipstick port location before installation. This oil pan does not include a gasket or seal, pickup, windage tray, crank shaft wiper, or installation hardware, so those components must be sourced separately as needed. Clean the sealing surface thoroughly and inspect the drain plug threads before filling with oil.

Quality Assurance

Dorman designs this oil pan as an OE-style replacement for specific vehicle years, makes, and models, with dimensions and features matched to the original pan configuration for dependable service fitment.
