Checking the functioning of the intake manifold flap
After installing the new lower intake manifold, remove the vacuum actuator mounting bracket.
Pic. 2.68. Connecting the hand vacuum pump
Connect the hand vacuum pump as follows (pic. 2.68).
Create a vacuum and check the serviceability of the actuator of the vacuum drive by the arm of the lever.
Note: With the intake manifold removed, the operation of the intake manifold flap can be checked at the same time.
