WARNING:

Never remove the radiator cap when the engine is hot. Serious burns could occur from high pressure

engine coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter

of a turn to release built-up pressure. Carefully remove radiator cap by truning it all the way.

CAUTION:

• When removing water pump, be careful not to get engine coolant on drive belt.

• Water pump cannot be disassembled and should be replaced as a unit.

• After installing water pump, connect hoses and clamps securely, then check for leaks.

REMOVAL

Removal of Thermostat

1. Partially drain engine coolant from the radiator. Refer to 

CO-11, "Changing Engine Coolant"

.

CAUTION:

Perform when engine is cold.

2. Disconnect the water suction hose from the water inlet.
3. Remove the water inlet and thermostat.

THERMOSTAT AND WATER PIPING

Removal of Thermostat Housing, Water Outlet and Heater Pipe

1. Remove the intake manifold. Refer to 

EM-26, "Removal and Installation"

.

2. Remove the thermostat housing, water outlet and heater pipe.

Removal of Water Cut Valve

1. Partially drain engine coolant from the radiator. Refer to 

CO-11, "Changing Engine Coolant"

.

CAUTION:

Perform when the engine is cold.

2. Disconnect the water cut valve connector.
3. Disconnect the water hoses from the water cut valve.
4. Remove the water cut valve.

INSPECTION AFTER REMOVAL

• Place a thread so that it is caught in the valve 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 tempera-

ture and check the valve closing temperature.

Standard values:

INSTALLATION

Installation is in the reverse order of removal.

Installation of Thermostat 

• Install the thermostat with the whole circumference of each flange

part fit securely inside the rubber ring as shown. 

• Install the thermostat with the jiggle valve facing upwards. 

Installation of Water Outlet Pipe and Heater Pipe

First apply a neutral detergent to the O-rings, then quickly insert the insertion parts of the water outlet pipe and

heater pipe into the installation holes.

INSPECTION AFTER INSTALLATION

• Check for leaks of the engine coolant. Refer to 

CO-10, "Inspection"

.

• Start and warm up the engine. Visually check for leaks of the engine coolant.
