Temperature Sensor

THERMAC Operation:

- Start test with air cleaner temperature below 30° C (86° F). If engine is hot, remove air cleaner cover and place a thermometer as close as possible to sensor. Replace air cleaner cover when temperature has fallen below the specified level.
- Start and idle engine. Damper door should move to close off outside air immediately if temperature is cool enough. When damper door starts to open, remove air cleaner cover and take a temperature reading. It should be about 55° C (131° F).
- If damper door did not open to outside air at the specified temperature, replace temperature sensor.
