Vacuum Pumps

What You Need to Know About Car Vacuum Pumps

Your car’s engine requires a constant vacuum source to operate properly. If your engine is naturally aspirated, then this source is simply the engine operation. It produces a vacuum source at all times. However, turbocharged engines need help. A turbocharger produces boost pressure, which is the opposite of a vacuum. This means that all modern engines with turbochargers also have a vacuum pump to counteract the boost pressure.

Vacuum pumps serve the purpose of providing a vacuum source to various places in the engine bay. For example, the power brake system has a booster that requires a vacuum. The vacuum pump ensures that the booster gets a constant vacuum to deliver enough braking force to stop. The turbocharger wastegate actuators also require a vacuum to perform correctly.

Signs of a failing vacuum pump include loud noise, delayed brake response, a hissing noise when you depress the brakes, or a rough idle. Sometimes, these symptoms can be mistaken for other things.
