To remove the oil pan, first raise the vehicle and support it securely on jackstands. Drain the engine oil, then clean and install the engine oil drain plug, tightening it to the specified torque. Remove and discard the oil filter for replacement. Next, take off the engine lower splash shield and support the engine and transmission from above with an engine support fixture. With the engine and transmission supported, remove the front subframe. Detach the transmission cooler line bracket fastener and remove the bracket from the cylinder block, followed by the three lower transmission-to-engine mounting bolts. Progressively unscrew the oil pan retaining bolts in reverse order of tightening, using a rubber mallet to loosen the oil pan seal before lowering it. Be cautious when prying between mating surfaces to avoid damage that could lead to leaks, and a putty knife may help cut through any sealant. For installation, thoroughly clean and degrease the mating surfaces of the lower engine block and oil pan, ensuring all traces of sealant are removed. Apply a 1/8-inch wide bead of sealant to the oil pan flange, keeping it approximately 3/16-inch from the outside edge and around the inside edge of the bolt holes, also applying sealant to the front flange. The oil pan must be installed within 4 minutes of applying the sealant. Install the oil pan, pressing it towards the rear, and install the oil pan bolts, tightening them only finger tight initially. Tighten the oil pan-to-engine block bolts gradually in a criss-cross pattern from the center outwards to the specified torque. Install the three transmission-to-engine fasteners and tighten them, then reinstall the subframe. Finally, lower the vehicle to the ground and wait at least 1 hour for the sealant to cure before refilling the engine with oil, trimming off any excess sealant and installing a new oil filter.
