To remove and install the oil pan, begin by disconnecting the negative battery cable and safely supporting the vehicle. Drain the engine oil into a sealable container and install the drain bolt with a new gasket, tightening it to 33 ft. lbs. (44 Nm). Remove the front wheels and splash shield, then detach the center beam and the Oxygen sensor electrical connector. Remove the bolts from the support bracket on the exhaust pipe, followed by the nuts attaching the exhaust pipe to the exhaust manifold and catalytic converter. Discard the exhaust pipe gaskets and, if equipped with an automatic transaxle, remove the converter cover; if equipped with a manual transaxle, remove the clutch cover. Remove the oil pan nuts and bolts in a criss-cross pattern, taking care not to pry on the pan. Clean the oil pan mounting surface of old gasket material and engine oil. For installation, place a new oil pan gasket on the oil pan, applying liquid gasket to the corners of the curved section. Install the oil pan and tighten the nuts and bolts in sequence, first to 10 ft. lbs. (14 Nm) in two steps. If applicable, install the torque converter cover or clutch cover, tightening the bolts to 108 inch lbs. (12 Nm). Install the exhaust pipe with new gaskets and lock nuts, tightening the manifold nuts to 40 ft. lbs. (54 Nm) and the catalytic converter nuts to 25 ft. lbs. (33 Nm). Attach the bolts to the exhaust pipe support bracket and tighten to 13 ft. lbs. (18 Nm), then reconnect the Oxygen sensor. Reinstall the center beam, tightening the mounting bolts according to the vehicle model specifications, followed by the splash shield and front wheels. Lower the vehicle, refill the engine with oil, reconnect the negative battery cable, enter the radio security code, and start the engine to check for leaks. For the 3.0L engine, the process begins similarly with the disconnection of the negative battery cable and vehicle support. Remove the engine undercover, drain the engine oil, and replace the drain plug. Remove the front exhaust pipe and oil pan mounting bolts, then use a seal cutter to break the seal between the engine block and oil pan before removing the oil pan. Clean the oil pan flange and engine block mounting surface, apply sealant to the oil pan flange, and install the oil pan, tightening the bolts in sequence to 8.7 ft. lbs. (12 Nm). Reinstall the exhaust pipe and undercover, lower the vehicle, refill the engine with oil, reconnect the negative battery cable, and start the engine to check for leaks.
