Removal of the thermostat would have an
adverse effect, causing a lowering of cooling efficiency. Do not
remove the thermostat, even if the engine tends to
overheat. |

Drain engine coolant so its level is below
thermostat. |
2. |
Remove the radiator lower hose
(A).

|
3. |

4. |
Installation is reverse order of
removal.
Install the thermostat with the jiggle
valve
upward. | |
5. |

7. |
Recheck the coolant
level. |
1. |
Immerse the thermostat in water and gradually
heat the water.

|
2. |
Check the valve opening
temperature.
Valve opening
temperature : 82°C (177°F)
Full opening
temperature : 95°C (205°F)
|
If the valve opening temperature is not as
specified, replace the thermostat. |
3. |
Check the valve lift.
Valve lift
: 8mm (0.3in.) or more at 95°C (205°F)
|
If the valve lift is not as specified, replace
the
thermostat. | |
