What It Helps Address

• Loss of oil due to a compromised drain area
• Faults related to a missing or damaged oil level sensor port

Installation Notes and Tips

Verify engine code, oil pan style, and sensor-port configuration before installation. This oil pan does not include a gasket or seal, so the sealing components should be selected separately. Clean the mating surfaces thoroughly, inspect the drain plug threads, and confirm all 24 bolt holes align before tightening to specification.
