Cleaning Procedure

WARNING: This page is about a different car, the 2005 Cadillac STS. However, it is still accessible from the selected car via links, so may be relevant.
    NOTE: Do not immerse the water pump in solvent. The solvent may enter the water pump's permanently lubricated bearings and cause premature bearing failure.
  1. Remove the old gasket material from the water pump sealing surfaces.
  2. Clean all excess dirt and debris from the water pump housing.
