REMOVAL
1. Drain engine coolant from radiator. Refer to
CO-12, "Changing Engine Coolant".
CAUTION:
• Perform this step when engine is cold.
• Never spill engine coolant on drive belt.
2. Remove air duct (inlet). Refer to EM-26, "
Exploded View".
3. Remove reservoir tank. Refer to CO-17, "
Component".
4. Add paint mark, then disconnect radiator hos e (lower) from water inlet. Refer to CO-17, "
Component".
5. Remove water inlet and thermostat. • Engine coolant will leak from cylinder block, so have a receptacle ready below.
INSTALLATION
Installation is in the reverse order of removal.
Thermostat
• Install thermostat making sure rubber ring (1) groove fits securelyto thermostat flange (A).

INSPECTION AFTER REMOVAL
WARNING:
Use a protector to prevent a burn during the work.
Thermostat
• 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 full-open valve lift amount, lower the water tem- perature and check the valve closing temperature.
• If out of the standard, replace thermostat.
INSPECTION AFTER INSTALLATION
• Check that the reservoir tank cap is tightened.
• Check for leaks of engine coolant using suitable tools. Refer to CO-12, "
Inspection".
• Start and warm up the engine. Visually make sure that there is no leaks of engine coolant.

Make sure to read the text of service manual.
• Within five minutes of liquid gasket application, install the mat- ing component.
• If liquid gasket protrudes, wipe it off immediately.
• Do not retighten nuts or bolts after the installation.
• After 30 minutes or more have passed from the installation, fill engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe them.
