  2. INSPECT WATER PUMP ASSEMBLY

    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 air hole 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 is no coolant leaking from any parts other than the engine water pump assembly. If there are leaks, inspect those areas.

    • Perform this inspection when the engine is cold.

      *1 Air Hole

      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.

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

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

  3. INSPECT FLUID COUPLING ASSEMBLY


    1. A01XHAM

      Remove the 4 nuts and fan.

    2. A01XIWF

      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:
      6.5 N*m  { 66 kgf*cm, 58 in.*lbf }
