Raise the vehicle and support it securely on jackstands, then remove the transaxle. If it's leaking, now would be a very good time to replace the front pump seal/O-ring for automatic transaxle only. Remove the pressure plate and clutch disc for manual transaxle equipped vehicles, and check or replace the clutch components and pilot bearing. Use a center-punch or paint to make alignment marks on the flywheel/driveplate and crankshaft to ensure correct alignment during reinstallation. Remove the bolts that secure the flywheel/driveplate to the crankshaft, and if the crankshaft turns, wedge a screwdriver in the ring gear teeth to jam the flywheel. Carefully remove the flywheel/driveplate from the crankshaft, supporting it while removing the last bolt, noting that automatic transaxle equipped vehicles have spacers on both sides of the driveplate. Clean the flywheel to remove grease and oil, inspecting the surface for cracks, rivet grooves, burned areas, and score marks, with light scoring removable using emery cloth. Check for cracked and broken ring gear teeth, laying the flywheel on a flat surface to check for warpage with a straightedge. Clean and inspect the mating surfaces of the flywheel/driveplate and the crankshaft, replacing the crankshaft rear seal if leaking before reinstalling. Position the flywheel/driveplate against the crankshaft, aligning the marks made during removal, and noting that some engines have an alignment dowel or staggered bolt holes for correct installation. Apply thread locking compound to the bolt threads before installation, then wedge a screwdriver in the ring gear teeth to keep the flywheel/driveplate from turning while tightening the bolts to the specified torque in a criss-cross pattern, working up to the final torque in three or four steps. The remainder of installation follows the reverse of the removal procedure.
