Cleaning the SUB-EGR Valve

22. Disconnect the sub-EGR valve linkage by pressing in on the retaining pin and spring, and pulling upward on the linkage.





23. Remove the rubber boot and then remove the Sub-EGR valve.

CAUTION:
When removing the boot, be careful not to damage it.





24. Clean the valve with carburetor cleaner (PIN 00212-19130 or equiv.). You may want to use a piece of very fine emery cloth to remove any carbon deposits. Clean the valve by twisting it on the emery cloth.

CAUTION:
Do not clean the valve with a wire brush or wheel to prevent scratching the valve. The scratches will allow the carbon to build up on the valve quickly.





25. Spray carburetor cleaner into the sub-EGR valve bore in the carburetor.





26. Re-install the sub-EGR valve in the carburetor. Re-install the rubber boot and re-connect the linkage to the valve.
