Vacuum Pump

The vacuum pump produces the vacuum power needed for vehicle functions such as braking and some HVAC functions.

Symptoms of a Bad or Failing Vacuum Pump

  • Brake pedal may be hard
  • Heating, ventilation, and AC (HVAC) system may malfunction
  • Abnormal noise

Vacuum Pump Related Repair Advice

  • It's a good idea to use a factory quality (OEM) vacuum pump. If the pump is belt driven, replace the drive belt as well.
  • Components that rely on the vacuum pump (climate control and/or brake system components) may be incorrectly replaced if there is an issue with the vacuum pump
  • Vacuum pumps are used on Diesel engines (since they do not produce vacuum) and on some gasoline engines that produce little vacuum, such as turbos
