PROCEDURE


  1. INSPECT FOR COOLANT LEAK

    Tech Tips


    • The sliding surface inside the engine water pump assembly is lubricated by engine coolant. As some engine coolant is discharged during normal operation, coolant residue (solids) may be found on the drain plug or the bottom of the engine water pump assembly. Engine coolant may leak if foreign matter enters the engine water pump assembly, however the sealing performance will recover when the foreign matter is pushed out or breaks into fine pieces.

    • Before performing this inspection, check that there are no engine coolant leaks from any parts other than the engine water pump assembly. If there are leaks, inspect those areas first.

    • Perform this inspection when the engine is cold.


    1. Visually check the engine water pump assembly.


      1. Check that engine coolant is not dripping from the engine water pump assembly.

        Tech Tips

        If engine coolant is dripping, replace the engine water pump assembly.
