Replacing my oil pan gasket on my 1994 Jeep Wrangler six-cylinder. It’s a good idea to disconnect the negative battery cable. Then drain the oil. When replacing the oil pan, replace the bolts starting in the center and work out. Torque specifications: 1/4 x 20 bolts 84 in-lbs. 5/16 x 18 bolts 132 in-lbs.
