INSPECTION AFTER REMOVAL
• Visually check if there is no significant dirt or rusting on water
pump body and vane (A).
• Make sure that there is no looseness in vane shaft, and that it turns smoothly when rotated by hand.
• Replace water pump, if necessary.
INSPECTION AFTER INSTALLATION
• Check that the reservoir tank cap is tightened.
• Check for leaks of engine coolant. Refer to CO-12, "
Inspection".
• Start and warm up the engine. Visually check for leaks of engine coolant.

INSPECTION AFTER REMOVAL
WARNING:
Use a protector to prevent a burn during the work.
Thermostat
• Place a thread (A) so that it is caught in the valves of thermostat(1). Immerse fully in a container (B) filled with water. Heat while
stirring.
• The valve opening temperature is the temperature at which the valve opens and falls from the thread.
• Continue heating. Check the full-open valve lift amount.
• After checking the full-open valve lift amount, lower the water tem- perature and check the valve closing temperature.
• If out of the standard, replace thermostat.
INSPECTION AFTER INSTALLATION
• Check that the reservoir tank cap is tightened.
• Check for leaks of engine coolant using suitable tools. Refer to CO-12, "
Inspection".
• Start and warm up the engine. Visually make sure that there is no leaks of engine coolant.
