4.. When replacing the oil pan, it is critical that a torque wrench is used to tighten the hex head screws. 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
retorque is important because the gasket material relaxes after the first tightening.
