Heated Air Induction System Test

1. Remove the air cleaner housing cover and air
cleaner element.

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.
3. Start the engine. Hold the engine at 3,000 rpm with
no load (in Park or neutral) until the radiator fan
comes on.
4. Check the air valve (A). The air valve should be
closed when the temperature at the wax element

• If the air valve is closed, the heated air induction
system is OK.

binding or sticking. If it is OK, replace the air
