Temperature Sensor

  1. Air cleaner temperature should be less than 86°F (30°C). Place thermometer as close to sensor inside air cleaner. Start and idle engine. Damper door should close off outside air immediately.
  2. When damper door starts to open snorkel passage, remove air cleaner cover and read thermometer temperature. Thermometer should read 131°F (55°C).
  3. If damper door does not open to outside air at the specified temperature, replace defective thermostatic air cleaner temperature sensor.
