WATER PUMP ON-VEHICLE INSPECTION

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. In this case, check the area around the engine water pump assembly.

    • 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.

        • If engine coolant is not dripping, perform the following check.

      *1 Water Hole
      *2 Air Hole

      Visually check the water hole and air hole for coolant leakage.

      If leakage is found, replace the engine water pump assembly.

    2. Turn the pulley and check that the pump bearing moves smoothly and quietly.

      If the bearing moves roughly or noisily, replace the engine water pump assembly.

  4. INSPECT FLUID COUPLING


    1. A01XKDV

      Remove the 4 nuts and fan.

    2. A01XMK8

      Check the fluid coupling for damage or silicon oil leaks. If necessary, replace the fluid coupling.

    3. Install the fan with the 4 nuts.

      Torque:
      6.0 N*m  { 61 kgf*cm, 53 in.*lbf }
