Disconnect the cable from the negative terminal of the battery. If working on a 3.5L engine, install an engine support fixture, raise the vehicle, and support it securely on jackstands. Drain the engine oil and remove the starter. Remove the air conditioning compressor mounting bolts and position it to the side. For 3.9L engines, disconnect the oil level sensor wiring. Remove all transaxle braces from the oil pan and then the oil pan mounting bolts. For 3.5L V6 models, remove the oil filter and its adapter, take the weight off the engine mounts using the engine support fixture, and remove the engine mount bracket from the front passenger side of the engine. Remove the torque converter bolts, ground wires, and wiring brackets from the transaxle. Loosen all transaxle-to-engine bolts a few turns without removing them, then raise the engine/transaxle assembly slightly. Remove the oil pan mounting bolts and pull the engine about 1/2-inch away from the transaxle to allow the oil pan to clear the protruding boss on the transaxle. Carefully separate the oil pan from the block without prying between the block and the pan to avoid damaging the sealing surfaces. Clean the pan with solvent, removing all old sealant and gasket material from the block and pan mating surfaces, and ensure the bolt holes in the block are clear. Apply a bead of RTV sealant to the front of the gasket and each side of the rear main cap, then install the new one-piece oil pan gasket. Place the oil pan in position on the block and install the nuts/bolts, tightening them to the specified torque starting at the center. After tightening the pan-to-block bolts, install the oil pan side bolts and tighten them to torque. For 2007 and later 3.5L models, re-join the engine and transaxle, tightening the bolts to torque, and install the
Flywheel/drive plate-to-torque converter bolts. Install the oil pan-to-transaxle brace and torque the bolts to specifications. For 3.9L V6 engines, install the transaxle brace and tighten the bolts to torque. The remaining steps are the reverse of the removal procedure, tightening the subframe bolts to torque. Refill the engine with oil, run it until normal operating temperature is reached, and check for leaks.
