INSPECTION
1) Check the water pump bearing for smooth rotation.
2) Check the water pump pulley for abnormalities.
3) Make sure the impeller is not deformed or damaged.
4) Inspect the clearance between impeller and pump case.
Clearance between impeller and pump case:
Specification: 0.5 - 1.5 mm (0.020 - 0.060 in)





5) After water pump installation, check pulley shaft for engine coolant leaks and noise. If a leak or noise is noted, replace the water pump assembly.
