REMOVAL
1. Drain engine coolant from drain plugs on radiat or and both side of cylinder block. Refer to CO-37, "Chang-
ing Engine Coolant" and EM-242, "Disassembly and Assembly".
CAUTION:
Perform this step when engine is cold.
Do not spill engine coolant on drive belts.
2. Remove engine cover with power tool. Refer to EM-169, "
Component".
3. Remove air duct (inlet). Refer to EM-173, "
Component".
4. Disconnect water suction hose from water inlet.
5. Remove water inlet and thermostat. CAUTION:
Do not disassemble thermostat.
6. Remove intake manifolds (upper and lower). Refer to EM-175, "
Component".
7. Disconnect radiator hose (upper) and wa ter hoses from thermostat housing.
8. Disconnect heater hoses from water outlet and heater pipe.
9. Remove thermostat housing, water outlet pipe, water connector, water control valve, water outlet and heater pipe.
CAUTION:
Do not disassemble water control valve.
INSPECTION AFTER REMOVAL
Make sure that valves both in thermostat and water c ontrol valve are completely closing at normal tempera-
ture.
Place a thread so that it is caught in the valves of the thermostat
and water control valve. Immerse fully in a container filled with
water. Heat while stirring. (The example in the figure shows ther-
mostat.)
The valve opening temperature is the temperature at which the valve opens and falls from the thread.
Continue heating. Check the maximum valve lift. NOTE:
The maximum valve lift standard temperature for water control
valve is the reference value.
After checking the maximum valve lift, lower the water tempera-
ture and check the valve closing temperature.
Standard values:
If the malfunctioning condition, when closing valve at nor mal temperature, or measured values are out of the
standard, replace thermostat and/or water control valve.
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Be careful not to spill engine coolant over en gine room. Use rag to absorb engine coolant.
