REMOVAL
1. Drain engine coolant. Refer to CO-8, "DRAINING ENGINE COOLANT" .
2. Remove water inlet.
3. Remove thermostat.
4. Remove water pump. Refer to CO-17, "
WAT ER PUM P" .
5. Remove thermostat housing.
INSPECTION AFTER REMOVAL

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 maximum valve lift amount, lower the water
temperature and check the valve closing temperature.

If out of the specification, replace thermostat.
INSTALLATION
Installation is in the reverse order of removal.
Thermostat
CAUTION:
Replace the rubber ring with a new one.

Install thermostat while making rubber ring (1) groove fit to ther-
mostat flange (A) around the whole circumference.

Install thermostat (1) into the thermostat housing (2) with jiggle
valve (A) facing upwards.
Thermostat Housing
CAUTION:
Replace the rubber ring with a new one.

Securely insert the rubber ring into the mating groove of thermostat housing and install it.

Install the thermostat housing to the cylinder block without displacing the gasket from the gasket position.
INSPECTION AFTER INSTALLATION

Check for leaks of engine coolant. Refer to CO-8, "CHECKING COOLING SYSTEM FOR LEAKS" .

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

INSPECTION AFTER REMOVAL

Place a thread (A) so that it is caught in the valves of water con-
trol valve (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.
NOTE:
The maximum valve lift amount standard temperature for water
control valve is the reference value.

After checking the maximum valve lift amount, lower the water
temperature and check the valve closing temperature.

If out of the specification, replace water control valve.
INSTALLATION
Installation is in the reverse order of removal.
Water Control Valve
CAUTION:
Replace the rubber ring with a new one.

Install water control valve while making rubber ring (1) groove fit
to water control valve flange (A) around the whole circumfer-
ence.

While the mark (A) points to up, install water control valve (2)
with frame center (B) facing straight upward into water outlet (1).
Water Outlet
Install the water control valve to the cylinder head without displacing the valve from the valve position.
Valve opening temperature 93.5 - 96.5°C (200 - 206°F)
Maximum valve lift 8 mm/ 108°C (0.315 in/ 226°F)
Valve closing temperature 90°C (194°F)
