Exploded View
- Water inlet
- Thermostat
- Rubber ring
- To radiator hose (lower)
NOTE: When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spilling.
Removal and Installation
WARNING: Do not 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 push down and turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by pushing it down and turning it all the way.
REMOVAL
- Drain engine coolant from the radiator. Refer to CO-8, "Draining".
CAUTION:
- Perform this step when the engine is cold.
- Do not spill coolant on drive belt.
- Remove engine under cover. Refer to EXT-37, "ENGINE UNDER COVER : Removal and Installation".
- Remove radiator hose (lower) from the water inlet side.
- Remove exhaust manifold heat shield. Refer to EM-29, "Exploded View".
- Remove water inlet and thermostat.
INSTALLATION
Installation is in the reverse order of removal.
- Install the thermostat with the whole circumference of the flange fitting securely inside the rubber ring.
CAUTION:
- Do not reuse rubber ring.
- Ensure thermostat rubber ring mounting surface is free from dents or flaws.
- Install the thermostat with the jiggle valve facing upwards. The position deviation may be within the range of ±20°.
- After installation, refill coolant and check for leaks. Refer to CO-9, "Refilling" and CO-8, "Inspection".
Inspection
INSPECTION AFTER REMOVAL
- Place a thread (A) so that it is caught in the valves of thermostat (1) and water control valve. Immerse fully in a container (B) filled with water. Heat while stirring. (The example in the figure shows thermostat.)
- The valve opening temperature is the temperature at which the valve opens and falls from the thread.
- Continue heating. Check the maximum 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
Standard Thermostat : Refer to CO-25, "Thermostat".
- If out of the standard, replace either or both thermostat and water control valve.
INSPECTION AFTER INSTALLATION
- Check for leakage of engine coolant using the radiator cap tester adapter (commercial service tool) and the radiator cap tester (commercial service tool). Refer to CO-8, "Inspection".
- Start and warm up engine. Check visually that there is no leakage of engine coolant.

Operating tips
When the engine coolant temperature and
outside air temperature are low, the air flow
from the foot outlets may not operate for a
maximum of 150 seconds. However, this is
not a malfunction. After the coolant temperature
warms up, air flow from the foot outlets
will operate normally.
