In most cases, the engine will not need to be raised, which will greatly ease the procedure, so inspect the pan clearance before beginning. Start by disconnecting the negative battery cable, then raise the car and support it firmly on jack stands. Drain the engine oil into a suitable container and remove the automatic transmission flex plate lower cover if equipped. Disconnect the exhaust crossover pipe at the manifolds, then remove the oil pan attaching bolts and take off the oil pan. Clean the pan thoroughly with the proper solvent, ensuring that the gasket surfaces on the block and pan are clean, smooth, and free of old gasket material. Apply sealer to the new oil pan gasket in several places and install it on the pan, making certain that the bolt holes line up. Finally, install the oil pan and pan bolts, torque-tightening the bolts to specifications.
