Heated Air Induction System Test
- Remove the air cleaner housing cover and air cleaner element.
- Check the air valve (A). The door should be open when the temperature at the wax element (B) is below 32°F (0°C).
- If the valve is open, go to step 3.
- If the valve is not open, check the shaft for binding or sticking. If it is OK, replace the air cleaner housing.

- Start the engine. Hold the engine at 3,000 rpm with no load (in Park or neutral) until the radiator fan comes on.
- Check the air valve (A). The air valve should be closed when the temperature at the wax element (B) is above 50° (10°C).
- If the air valve is closed, the heated air induction system is OK.
- If the air valve is not closed, check the shaft for binding or sticking. If it is OK, replace the air cleaner housing.
