INSPECT FOR COOLANT LEAK
Tip:
- 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 is no coolant leaking from any parts other than the water pump. If there are leaks, inspect those areas.
- 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.
    Tip:
    - If engine coolant is dripping, replace the engine water pump assembly.
    - If engine coolant is not dripping, perform the following check.
2. Inspect the area around the engine water pump.
  
  Tip:
  Check for deposits around the drain plug of the engine water pump.
  1. Remove the fan and generator V belt (Click here).
  2. Remove the water pump pulley (Click here).
  3. Press a piece of paper towel against the drain plug or deposits on the lip of the drain plug and check that the paper towel is not wet.

    If the paper towel is wet, replace the engine water pump assembly.
    If the paper towel is not wet, thoroughly clean the area around the engine water pump.
3. Install the water pump pulley (Click here).
