Cruise Control Vacuum Reservoir: Description and Operation
The vacuum reservoir is located in the engine compartment. It is made of plastic.
The reservoir stores engine vacuum. Manifold vacuum is supplied from the brake booster check valve. The speed control vacuum supply hose has a
check valve at the source (brake booster) to maintain the highest available vacuum level in the servo, reservoir and vacuum hoses. When engine vacuum
drops, as in climbing a grade while driving, the reservoir supplies the vacuum needed to maintain proper speed control operation. The vacuum reservoir
cannot be repaired and must be replaced if faulty.
