REMOVAL

1.

Completely drain engine coolant. Refer to 

CO-10, "DRAINING ENGINE COOLANT"

 .

CAUTION:

●

Perform this step when engine is cold.

●

Do not spill engine coolant on drive belts.

2.

Remove air duct and air cleaner case. Refer to 

EM-16, "Removal and Installation"

 .

3.

Disconnect radiator hose (lower) and oil cooler hose from water inlet and thermostat assembly.

4.

Remove water inlet and thermostat assembly.

CAUTION:

Do not disassemble water inlet and thermostat assembly.
Replace them as a unit, if necessary.

INSPECTION AFTER REMOVAL

1.

Check valve seating condition at ordinary room temperatures. It should seat tightly.

2.

Check valve operation.

●

If the malfunctioning condition, when valve seating at ordinary
room temperature, or measured values are out of the standard,
replace water inlet and thermostat assembly.

Installation is in the reverse order of removal, paying attention to the following.

●

Be careful not to spill engine coolant over engine room. Use rag to absorb engine coolant.

INSPECTION AFTER INSTALLATION

●

Check for leaks of engine coolant using tool. Refer to 

CO-9, "CHECKING COOLING SYSTEM FOR

LEAKS"

 .

●

Start and warm up engine. Visually check there are no leaks of engine coolant.
