c. Cleaning and Inspection. Wash all parts in cleaning solvent and dry them with clean compressed air or a soft
absorbent cloth. Use a stiff wire brush to remove all scale, lime, and rust deposits from the shaft, impeller, and water
pump body. Clean the pipe plug threads and all mounting screws with a stiff wire brush and inspect them for corroded,
etched, damaged, or stripped threads. Inspect the water pump body, impeller, and machined gasket surfaces for etching,
cracks, damage, and wear. Replace the water pump body if it is badly etched, corroded, or cracked.
