GM 19256218 Oil Pan

Drain the engine oil. Loosen the right-front wheel lug nuts, raise the front of the vehicle and support it securely on jackstands. Remove the right front wheel. Remove the splash shield from below the right side of the engine compartment. Remove the splash shield mounting bolts-one bolt can be removed through the access hole in the inner fender splash shield. Remove the lower air conditioning compressor mounting bolt. Loosen, but don't remove, the other compressor mounting bolts. Remove the dipstick and the dipstick tube. The tube is bolted to the intake manifold. Remove the oil pan bolts. Follow the reverse of the tightening sequence. Tighten the pan-to-transaxle bolts until they're snug, then tighten the pan to block bolts in numerical order to the torque listed in the Specifications, then tighten bolts to the specific torque. Carefully remove the oil pan from the lower crankcase. If the oil pan is difficult to separate from the lower crankcase, use a rubber mallet or a block of wood and a hammer to jar it loose. If it's stubborn and still won't come off, pry carefully on casting protrusions. Using a gasket scraper, thoroughly clean all old gasket material from the lower crankcase and oil pan. Remove residue and oil film with a solvent such as acetone or lacquer thinner. Apply a 2 mm bead of RTV sealant to the perimeter of the oil pan, inboard of the bolt holes, and around the oil suction port. Allow the sealant to set-up before installing the oil pan to the engine. Install the oil pan and bolts. Tighten the pan-to-transaxle bolts until they're snug, then tighten the pan to block bolts in numerical order to the torque listed in the Specifications, then tighten bolts to the specific torque. Follow the correct torque sequence and tighten the bolts to the specific torque. The remaining installation is the reverse of removal. Be sure to tighten the wheel lug nuts to the specific torque.
