Installation Notes and Tips

Verify tooth count, outside diameter, and mounting dimensions before installation. Confirm the application uses a 162-tooth flexplate and matches the listed GM fitment for Buick Riviera, Oldsmobile Toronado, Cadillac Eldorado, Cadillac Seville, or Oldsmobile 98. Inspect the starter, crankshaft flange, and transmission interface for wear before installing the new flexplate.
