MotorVac Intake Cleaning System Procedures - Manual (Page 4)

Throttle Body and Carburetor Systems
1. Warm up vehicle to operating temperature.
2. Shut off vehicle and remove air cleaner.
3. Open the ICS Spray Bottle and add 4 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
4. Spray any exposed areas, air horn, choke plate, etc....with a generous amount of cleaner (one or two
ounces) and let soak.
5. Once the exposed areas are coated, insert the 30" Soak Tube into the nozzle. Open the throttle plate and
slide the Soak Tube into the manifold through the carburetor or TBI. Spray the inside of the intake
manifold with cleaner making sure to move the Soak Tube in a circular motion so that as much of the
floor of the manifold as possible will be soaked with cleaner.
IMPORTANT
Use only half the contents (4 oz.) at this time.
Using too much may fill a cylinder in smaller
engines.
6. Start the vehicle. While the vehicle is running, spray the remainder of the cleaner in through the throttle
plate in several short bursts. If the vehicle seems to be stalling, stop spraying for a moment to allow the
engine to return to a normal idle and repeat.
7. Re-install air cleaner, start the vehicle and test drive, or return to appropriate cleaning process.
