Removal Procedure

WARNING: This page is about a different car, the 2003 GMC Sierra and 2003 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.
  1. Remove the drive belt. Refer to Drive Belt Replacement .
  2. Remove the cooling fan. Refer to FAN REPLACEMENT .
    NOTE: To prevent damage to the end of the crankshaft when using a crankshaft balancer removal tool install a bolt in the crankshaft. Use a shorter bolt with the same threads as the crankshaft balancer bolt. This bolt will allow a place for the tool to push against. The shorter bolt is to keep from going past the threads in the crankshaft and damaging the crankshaft threads.
  3. Remove the crankshaft balancer bolt and washer.
