What is the Vacuum Pump all about?

While all gasoline engines create vacuums during operation, sometimes the amount created isn’t enough to power the accessory systems in the car. Diesel engines do not create vacuums at all during operation. In both of these instances, a vacuum pump is used to either augment or provide the vacuum power necessary to operate the various other systems on the car, including the brakes, some HVAC functions and more. The vacuum pump is usually located behind the engine, mounted near the firewall and close to the master cylinder and brake booster. It’s easily recognizable for its two nozzles on top, as well as the design of the canister. It is an electric air pump that maintains a constant amount of vacuum in the vacuum reservoir behind the front bumper. If the vacuum pump stops working or develops a leak, the engine compartment may release a hissing sound, the heater controls may not switch when operated, or the brake pedal may be hard to depress.
