This is when the cruise control vacuum reservoir does its job by stabilizing the vacuum pressure inside the servo. When the engine RPM's increase, the engine vacuum lowers. The cruise control vacuum reservoir contains a negative pressure inside the tank. The servo which controls the throttle linkage needs a constant supply of vacuum to maintain the throttle's position once the system is triggered by the driver. Part 1 of 3: Determining the symptoms of a bad cruise control vacuum reservoirīefore the use of electronic throttle controls and electronically powered cruise controls, most cruise control systems were powered by vacuum pressure. Consult your vehicle service manual as needed. The specific location and steps for removing this component may vary based on the vehicle you own.

Note: For purposes of this article, we will discuss the steps for removing and replacing the cruise control vacuum reservoir that is most common.

Each manufacturer has a special location for this part, so refer to your service manual if any confusion arises. We will outline the steps needed to replace a cruise control vacuum reservoir attached to a servo which is the most common application for this component. Replacing this component is rather simple as it's usually attached to a strap system or bolted onto a bracket. Most of the time, this part is located behind a front bumper or underneath the dashboard and is connected directly to the cruise control module or servo. The cruise control vacuum reservoir is designed to store a consistent supply of air that is vacuum pressurized to assist the servo in maintaining vacuum pressure. Today's modern replacements are made of plastic or durable polymers built to withstand the elements and should last for a very long time. This requires a car owner to have the vacuum reservoir replaced.

The original cruise control vacuum reservoir was commonly made of out sheet metal and rusted out.

This system was very consistent and rarely had any problems except for one: the vacuum tank or cruise control vacuum reservoir was prone to premature wear and tear. Older vehicles manufactured prior to 1996 typically utilized a vacuum-operated cruise control that used vacuum pressure to hold and release the throttle cable.
