                          Do not immerse the water pump in solvent. The solvent may enter the water pump's permanently lubricated bearings and cause premature bearing failure.

            | Note |  
            | 
              The water pump hub and impeller should turn straight and smoothly. If the hub wobbles, is noisy, or feels rough when rotated, replace the water pump.
              |  Rotate the water pump hub (2).

       |  | • | Damage to the water pump gasket sealing surface (3) 
 
 | 
     
    
   
   
    
     
      
       |  | • | Damage, corrosion or restrictions
