Installation Notes and Tips

Verify engine application and pan style before installation, since GM HD truck fitment can vary by engine configuration. This oil pan does not include a gasket or seal, so the correct sealing components must be sourced separately. Clean the mating surfaces thoroughly, inspect the drain plug threads, and confirm proper torque during installation to help prevent leaks. Fits 2017-2019 Chevrolet Silverado 2500 HD, N/A.
