CAUTION! Never use a throttle depressor to keep the engine above idle during service.

  1. Add BG Platinum® 44K® to fuel tank.
  2. For best results, add BG Platinum® 44K® to a full tank of gas. If the tank is not full, fill it up after the service.
  3. Fill supply tool with BG Platinum® Air Intake, Valve & Combustion Chamber Cleaner.

    CAUTION! This cleaner will damage paint and certain plastic materials.

  5. Locate and disconnect vacuum line.
  6. Use a shop towel to remove any oil residue from inside the vacuum port.
  7. Insert the adaptor into the vacuum port.
  8. Rotate adaptor vent cap so arrow is pointing forward. Make sure air flow is not restricted and the holes on the adaptor remain uncovered.
  9. Locate and disconnect the Valvetronic actuator.
  10. Start engine and allow vehicle to warm up to operating temperature.

  11. Install the BG Rev-It® (PN E101-4110) into the vehicle.  Follow the on screen instructions to ensure the vehicle is being revved to 3500 RPM throughout the Platinum service.  If the BG Rev-It® is not available, the vehicle MUST be revved manually following the “IMPORTANT” steps below!

    IMPORTANT! While performing the service, rev the engine (snap throttle) quickly three times every 45 seconds to a target RPM of 3,500. This will ensure that any cleaner accumulation has cleared. If the vehicle revs cannot be raised above 2,500 RPM during the snap throttle or the vehicle does not return to idle, the service should not be performed.
    Warning! Failure to rev the vehicle during the service may result in engine damage!
  12. Open ball valve on supply hose.
  13. The adaptor will administer 22 oz. (650 mL) of cleaner in 25–40 minutes depending on engine vacuum. When supply tool is empty, close ball valve and allow the engine to idle for 15 minutes.
  14. Add a second 22 oz. (650 mL) can of cleaner to the supply tool and open the ball valve.
  15. When supply tool is empty, close ball valve and turn engine off.
  16. Remove adaptor and reinstall vacuum line. Reconnect the Valvetronic actuator.
  17. Immediately test drive the vehicle for at least 15 minutes to clear any residual product.

    NOTE: If the vehicle cannot be driven after the service, the vehicle must idle for 30 minutes to clear any residual product.

    Warning! Failure to test drive or idle the vehicle after service may result in engine damage.
  18. Clear any codes that may have set.
