To remove and install parts for the 2.3L 4-Cylinder and 2.9L 6-Cylinder engines, begin by disconnecting the negative battery cable and safely raising the vehicle. Drain the engine oil and remove the splash guard if a vehicle has one. For 2.3L engines, remove the engine mount retaining nuts, the tower bolting and loosen the top bolt on the steering column yoke before sliding the yoke assembly up on the steering shaft. Raise and support the front of the engine, and remove the retaining bolts for the front axle crossmember and the crossmember itself. Next, remove the left engine mount, pan support bracket and pan bolts to remove the pan. Clean thoroughly the gasket mating surfaces, and mount oil pan together with new gaskets, and tighten bolts in crisscross fashion to 8 ft. lbs. (11 Nm). Lower the engine, install all engine mounts, and the front crossmember with its bolts. For 2.3L engines, remove the yoke assembly from the steering shaft and re-install it, tightening the bolts to 18 ft. lbs. (24 Nm). re-install the splash guard if applicable drop the car lower down reconnect the negative battery cable fill the engine with oil start the engine let it run until operating temperature check for leaks. For the 2.8L 8-Cylinder engine, disconnect the negative battery cable, raise and support the vehicle, remove the splash guard, drain the crankcase and remove the oil pan retaining bolts before swiveling the pan past the stabilizing bar to remove it. Clean the gasket mating surfaces, install the oil pan with a new gasket, tighten the bolts in a crisscross pattern to 6-8 ft. lbs. (8-11 Nm). Reinstall the splash guard, lower the vehicle, fill the crankcase with oil, attach the negative battery cable, start the engine, let it warm up to operating temperature and check for leaks. For the 2.3L and 2.4L 5-Cylinder engines, with the engine removed, remove the oil filter and oil pan bolts, carefully banging on the oil pan to break the seal and remove it and the oil passage O-rings. Clean the mating surfaces of the cylinder block and oil pan, coat new oil passage O-rings with engine oil and fit them in the cylinder block, apply a thin coat of gasket sealant on the engine block, fit the oil pan and pan bolts, tighten the pan bolts in a criss-cross pattern to 12 ft. lbs. (17 Nm) and finally fit the oil filter.
