Cleaning Through a Vacuum Port for Added Carbon Removal Capabilities
1. Warm up vehicle to operating temperature.
2. Open the ICS Spray Bottle and add 8 oz. of intake cleaning detergent. Pressurize with shop air and
insert the short (6”) Spray Tube into the Nozzle.
IMPORTANT
DO NOT EXCEED 185 PSI
USE SAFETY GLASSES
3. Start the vehicle. Locate a suitable vacuum port as close as possible to the throttle plate and insert the short
Soak Tube into the vacuum hose (in some cases it may be necessary to use the PCV hose as an inlet).
4. While the engine is idling, hold the ICS Spray Bottle upright and begin spraying cleaner into the engine.
If the vehicle seems to be stalling, stop spraying for a moment to allow the engine to return to a normal
idle and repeat.
5. When the ICS Spray Bottle is empty remove it from the engine, re-install the vacuum hose (or PCV
hose) and test drive the vehicle, or return to appropriate cleaning process.
