  Q: How do you remove, inspect, and reinstall the flywheel/driveplate on V6 Nissan Altima?

  A: Remove the engine/transaxle assembly from the vehicle and then separate the transaxle from the engine. If the vehicle has a manual transmission, remove the pressure plate and clutch disc, taking this opportunity to check or replace the clutch components and pilot bearing if necessary. For an automatic transmission, check and replace the front pump seal/O-ring. Use paint or a center-punch to make alignment marks on the flywheel/driveplate and crankshaft to ensure correct alignment during reinstallation. Remove the bolts securing the flywheel/driveplate to the crankshaft, holding the flywheel with a pry bar or wedging a screwdriver into the ring gear teeth if the crankshaft turns. Carefully remove the flywheel/driveplate from the crankshaft, supporting it while removing the last bolt due to its weight. 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 or a loose ring gear, 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 crankshaft, replacing the crankshaft rear seal if it is leaking before reinstalling the flywheel/driveplate. Position the flywheel/driveplate against the crankshaft, aligning the marks made during removal, 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, and wedge a screwdriver into the ring gear teeth to prevent the flywheel/driveplate from turning while tightening the bolts to the specified torque. The remainder of the installation follows the reverse order of removal.
