Temperature Sensor
- Air cleaner temperature should be less than 86°F (30°C). Place thermometer as close as possible to sensor inside air cleaner. Start and idle engine. Damper door should close off outside air immediately.
- When damper door starts to open snorkel passage, remove air cleaner cover and read thermometer temperature. Thermometer should read about 131°F (55°C).
- If damper door does not open to outside air at specified temperature, check vacuum motor diaphragm. If okay, replace defective thermostatic air cleaner temperature sensor.
