Installation Procedure
Notice: Internal components of this booster are not serviceable. The housing must not be unstaked and separated. Separating the housing will cause
permanent deformation, preventing the booster from holding proper volume.
Notice: Inspect the locking flanges on booster and mounting plate. Replace the booster and mounting plate if the locking flanges are bent or damaged.
1. Install the vacuum brake booster.
Position the vacuum brake booster on the cowl counterclockwise from the final installation position so that the locking flanges on the vacuum
brake booster and on the cowl mounting flange engage.
Important: Ensure that the locking tab and the flanges are in the fully engaged position.
