How to properly remove and reinstall a flywheel in 2.4L four cylinder engine on GMC Terrain?

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. Use a center punch or paint to make alignment marks on the driveplate and crankshaft to ensure correct alignment during reinstallation. Remove the bolts that secure the driveplate to the crankshaft; if the crankshaft turns, wedge a screwdriver in the ring gear teeth. Take off the driveplate from the crankshaft, noting the orientation of any spacer present between the crankshaft and the driveplate. Inspect the surface of the driveplate for cracks and clean and inspect the mating surfaces of the driveplate and the crankshaft. If the crankshaft rear seal is leaking, replace it before reinstalling the driveplate. Position the driveplate against the crankshaft, installing the spacer if one was present originally, and align the mating marks made during removal. Some engines may have an alignment dowel or staggered bolt holes to ensure correct installation. Before installing the bolts, apply thread locking compound to the threads. Wedge a screwdriver in the ring gear teeth to keep the driveplate from turning and tighten the bolts to the specified torque, working up to the final torque in three or four steps. The remainder of the installation follows the reverse order of removal.

GMC Flywheel Parts Questions & Experts Answers

Automatic Transmission Flexible Plate Assembly
12597026
Q: How to properly remove and reinstall a flywheel in 2.4L four cylinder engine on GMC Terrain?
A:
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. Use a center punch or paint to make alignment marks on the driveplate and crankshaft to ensure correct alignment during reinstallation. Remove the bolts that secure the driveplate to the crankshaft; if the crankshaft turns, wedge a screwdriver in the ring gear teeth. Take off the driveplate from the crankshaft, noting the orientation of any spacer present between the crankshaft and the driveplate. Inspect the surface of the driveplate for cracks and clean and inspect the mating surfaces of the driveplate and the crankshaft. If the crankshaft rear seal is leaking, replace it before reinstalling the driveplate. Position the driveplate against the crankshaft, installing the spacer if one was present originally, and align the mating marks made during removal. Some engines may have an alignment dowel or staggered bolt holes to ensure correct installation. Before installing the bolts, apply thread locking compound to the threads. Wedge a screwdriver in the ring gear teeth to keep the driveplate from turning and tighten the bolts to the specified torque, working up to the final torque in three or four steps. The remainder of the installation follows the reverse order of removal.
