AIR INTAKE CIRCUIT DIAGRAM

Diagram of the air intake circuit showing numbered components including warm air intake, actuator, cold air fitting, air cleaner, thermostatic valve, vacuum ducts, vacuum socket, and throttle case. An inset shows deflector positions A and B with airflow arrows.
  1. Warm air intake on exhaust manifold
  2. Actuator for warm/cold air deflector
  3. Cold air intake fitting
  4. Air cleaner
  5. Thermostatic valve
  6. Vacuum ducts
  7. Vacuum socket
  8. Throttle case

The air intake circuits comprises various components which ensure sufficient air is carried to the engine under different service conditions.

The intake of warm or cold air is selected by deflector (2) which may or may not be affected by the vacuum in the intake manifold according to position of thermostatic valve (5).

More specifically, when intake air temperature exceeds 9°C, thermostatic valve (5) stays closed and does not allow the vacuum to reach actuator (2) (position B).

Viceversa, when intake air temperature drops below 9°C, the thermostatic valve (5) opens to allow a vacuum through to actuator (2) (position A).
