WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could occur from high pressure
engine coolant escaping from the radiator.
REMOVAL
1. Remove the under cover, splash cover (right), and drive belt.
2. Drain engine coolant. Refer to CO-29, "
DRAINING ENGINE COOLANT" .
CAUTION:
Perform when the engine is cold.
3. Support the bottom of the oil pan with a floor jack etc, and remove the right engine mount bracket (front
side of the engine).
4. Remove the water pump pulley.
●Loosen the pulley bolts after fixing the pulley using a screwdriver etc.
5. Remove engine mount bracket.
6. Remove the water pump.
●Engine coolant will leak from the cylinder block, so have a receptacle ready below.
CAUTION:
●Handle the water pump vane so that it does not contact any other parts.
●Water pump cannot be disassembled and should be replaced as a unit.
INSPECTION AFTER REMOVAL
●Visually check that there is no significant dirt or rusting on the
water pump body and vane.
●Check that there is no looseness in the vane shaft, and that it
turns smoothly when rotated by hand.
●If there are any unusualness, replace the water pump assembly.

●Place a string so that it is caught in the valves of the thermostat.
Immerse fully in a container 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 lift amount.
● After checking the full-open lift amount, lower the water temper-
ature and check the valve closing temperature.
