INSPECTION

M1141002501884

.

Thermostat Check

1. Immerse the thermostat in water, and heat the water while 

stirring. Check the thermostat valve opening temperature.

Standard value:

Valve opening temperature:

87 

± 1.5°C (189 ± 3°F) <2.4L ENGINE>

82 

± 1.5°C (180 ± 3°F) <3.0L ENGINE>

2. Check that the amount of valve lift is at the standard value 

when the water is at the full-opening temperature.
NOTE: Measure the valve height when the thermostat is 
fully closed, and use this measurement to compare the 
valve height when the thermostat is fully open.

Standard value:

Full-opening temperature: 95

°C (203°F)

Amount of valve lift:

8.5 mm (0.335 inch) or more <2.4L ENGINE>
9.0 mm (0.354 inch) or more <3.0L ENGINE>
