Water Pump -- On-Vehicle Inspection



1. INSPECT FOR COOLANT LEAK
HINT:
  1. 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.
  2. Perform this inspection when the engine is cold.

  1. Visually inspect the engine compartment for the following conditions:

    1. There is a large amount of coolant in the engine compartment or on the underside of the hood near the fan and generator V belt.

    2. Liquid coolant is dripping from around the water pump.

    3. The coolant level in the reservoir is below the L line and there are traces of leakage around the water pump.
      If any of the above conditions exist, replace the water pump assembly.
      If none of the above conditions exist, perform the following inspection (inspection of the area around the water pump).

  1. Remove the fan and generator V belt (RAV4_ACA30 RM000000RPT00WX.html).

  1. Move the water pump pulley so that the drain plug can be reached (RAV4_ACA30 RM00000254E008X_01_0014.html).
