Water Pump: Inspection

2001 Chevrolet Cavalier LS, 2.4 TSECTION Inspection
WARNING: This page is about a different car, the 2003 Cadillac Seville and 2003 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.
  1. DO NOT immerse the water pump in solvent. The solvent may enter the water pump's permanently lubricated bearings and cause premature bearing failure. Rotate the water pump. See Fig 1. The water pump should turn straight and smoothly. If the hub wobbles, is noisy, or feels "lumpy" when turned, replace the water pump.
  2. Inspect the water crossover assembly for signs of leakage. If coolant leakage is evident, inspect and replace the "O" ring seal in the crossover housing. Examine the water pump shaft on the pulley side of the pump. If coolant leakage is evident, replace the water pump.
