When replacing the oil pan, it is critical that a torque wrench is used to tighten the hex head screw. DO NOT USE IMPACT WRENCH.

Torque all hex head screws to 11.0 N-m (9.0 ft.lbs.), then retorque all the hex head screws a second time to the same specifications as above. The
second re-torque is important because the gasket material relaxes after the first tightening.
