  1. 1

    Start vehicle and allow to idle for 5 to 10 minutes.

  2. 2

    Using pliers, remove the vacuum hose from the side of the brake booster that leads to the intake. It is only necessary to remove this one side of the hose.

  3. 3

    While car is running, slowly pour cleaner into the line. A slow pour will prevent a stall in the engine. Expect smoke. Smoking is a result of the carbon cleaner.

  4. 4

    Let the engine run for 5 to 10 minutes once the carbon cleaner is added to the vehicle. Carbon will slowly break down and release through the exhaust.

  5. 5

    Replace the hose while engine is idling. This area should not be too hot to touch; however, as a precautionary measure, you can wear protective gloves.

Tips and warnings

  • Seafoam carbon cleaner is highly recommended.
