NOTE: If the ICS container has too much cleaner in it, there may not be enough air volume to
force the cleaner out with sufficient velocity to contact the intake air plenum walls. Always be
sure to maintain at least 80 pounds of pressure in the ICS container.
6. Be certain that the ICS 30-inch spray tube is free from any kinks or bends.
7. Attach the spray tube to the end of the ICS container.
8. Measure the length of the engine air intake manifold by laying the spray tube outside the manifold.
9. At the throttle plate, grip and hold the tube.
Note: This will be the maximum length that the tube may be inserted into the manifold.
CAUTION: CIS FUEL SYSTEMS
Do not open or move sensor plate / air door on the engine when the fuel distributor is pressurized. The
CIS system will spray fuel into the engine while it is not running.
10. With the engine off and the engine’s air duct removed, open the throttle plate wide open or have
someone hold it open.
11. Insert the ICS spray tube into the manifold up to the point measured in step 8 and 9.
12. While holding the container upright, press and hold the nozzle of the ICS container and quickly pull the
spray tube to the open end of the manifold near the throttle plate.
13. Release the nozzle once the tip of the spray tube gets near the throttle plate.
Note: Do not spray outside of the throttle bore housing.
14. If the MotorVac CarbonClean
®
System is in use at the time, press the STOP button or Turn the timer
knob to the zero position to depressurize the engine’s fuel system.
Warning It is recommended that after each pass with the ICS container, the engine should be
“bumped over” using the starter. DO NOT ALLOW THE ENGINE TO START. Premature hydro
lock condition may be present if excess fluid is present.
Note: Allow 15 minutes of soak time before starting the vehicle.
15. Quickly turn the ignition to the start position then back to the off position to rotate the engine over
slightly.
The continuation of the cleaning service will require the installation of the 6-inch spray tube to clean the
Idle Air Control passage while the engine is running.
Note: Disconnecting and grounding the secondary ignition will also keep the engine from
starting.
16. Repeat these procedures a maximum of three times
17. After the air intake has been cleaned it will be necessary to start the engine and continue with the
cleaning process.
