- Position the new oil pan gasket correctly on the clean oil pan.
- Reinstall the oil pan, tightening the bolts in a crisscross pattern to the manufacturer's specified torque to ensure even pressure.
- Reinstall any components that were removed in step 2.
- Refill the engine with the correct type and amount of motor oil as per your owner's manual.
- Start the engine and carefully inspect for any oil leaks around the newly sealed oil pan.
