Disconnect the cable from the negative battery terminal, remove the oil dipstick, drain the engine oil, and remove the oil filter. Raise the vehicle and secure it on jackstands, then remove the crossmember bolts and the crossmember. Take out the engine mount through-bolts and raise the engine about two inches with an engine hoist properly attached to the lifting brackets, avoiding the use of a jack under the oil pan to prevent damage. Remove the oil pan-to-transmission bolts and the oil pan-to-engine bolts, then take off the oil pan, breaking the seal if necessary with a thin putty knife while ensuring not to gouge the sealing edge. Empty any residual oil from the pan and clean it with solvent. For installation, use a gasket scraper or putty knife to remove old gasket material and sealant from the pan and engine block, clean the mating surfaces, and use gasket adhesive to hold the rear rubber seal in place. Stick the side gaskets on the engine block with adhesive and apply RTV sealant at the corners where the side gaskets meet the end seals. Create alignment dowels from two long bolts, apply a bead of sealant on the block and front cover, and ensure the oil pan is installed within 15 minutes to prevent the sealant from hardening. Position the pan against the engine block, install the bolts finger tight, and then tighten them in the correct sequence, replacing the alignment studs with pan bolts. Complete the remaining steps in reverse order, remembering to add engine oil and install a new oil filler. Start the engine and check for oil leaks at the oil pan, then drive the vehicle and check again.
