SERVICE PROCEDURE (PROCEDURE TO MOVE CANISTER SOLENOID AND ALSO ON REAR HVAC VEHICLES ONLY, RPO C34, INSTALL SHIELD)

1. HOIST VEHICLE.

2. DISCONNECT THE WIRE HARNESS FROM THE CANISTER SOLENOID. DISCONNECT THE TWO SMALL VACUUM LINES AND ONE LARGE VACUUM LINE FROM THE CANISTER, AS SHOWN IN FIGURE 1. REMOVE THE CANISTER AND BRACKET ASSEMBLY.

3. REMOVE THE CANISTER AND THE CANISTER SOLENOID FROM THE BRACKET. LEAVE THE VACUUM HOSE ATTACHED TO THE SOLENOID.

4. CUT THE BRACKET AS SHOWN IN FIGURE 2. THE CUT-OFF PIECE WILL BE USED TO MAKE A NEW MOUNTING BRACKET FOR THE SOLENOID. FLATTEN THE BRACKET, THEN REBEND IN THE OPPOSITE DIRECTION, WITH THE NEW BEND LINE 1/4" (6 MM) UP FROM THE ORIGINAL BEND LINE.

5. MOUNT THE CANISTER BACK INTO THE ORIGINAL BRACKET, AND REINSTALL. REATTACH THE TWO SMALL VACUUM LINES.

6. DRILL A 1/4" (6.5 MM) HOLE IN THE BRACKET, IN THE CENTER OF THE MOUNTING LEG. CLIP THE SOLENOID ONTO THE RE-FORMED BRACKET. REMOVE THE VACUUM HOSE, THEN ATTACH THE OPPOSITE END OF THE HOSE TO THE SOLENOID. SECURE WITH THE EXISTING HOSE CLAMP.

7. HOLD THE BRACKET IN PLACE, IN THE AREA SHOWN IN FIGURE 3. THE HOLE IN THE BRACKET SHOULD BE JUST BEHIND THE FUEL TANK STRAP HOLE. MARK THE HOLE LOCATION, THEN DRILL A 13/64" (5.0 MM) HOLE IN THE FRAME. MOUNT THE SOLENOID USING A SELF-TAPPING, GALVANIZED SCREW, P/N 12337828 OR EQUIVALENT. THE HOSE SHOULD BE FACING THE REAR OF THE VEHICLE, AND LOOP BACK TOWARD THE FRONT, INSIDE THE FUEL TANK STRAP.

NOTE: IF THE VEHICLE HAS REAR AIR CONDITIONING (RPO C34), FOLLOW STEP 8 TO FABRICATE AND ATTACH THE SHIELD SHOWN IN FIGURE 4. IF THE VEHICLE DOES NOT HAVE REAR AIR CONDITIONING (RPO C34), PROCEED TO STEP 9.

NOTE: IF THE VEHICLE IS EQUIPPED WITH OPTIONAL REAR AIR CONDITIONING (RPO C34), THE REFRIGERANT LINES WILL BE DIRECTLY BELOW THE NEW SOLENOID LOCATION. UNLATCH THE ATTACHING CLIPS IN FRONT OF THE SOLENOID LOCATION TO ALLOW MOVEMENT OF THE PIPES.

CAUTION:

USE OF LEATHER GLOVES WHEN CUTTING AND INSTALLING THE SHEET METAL SHIELD IS RECOMMENDED TO AVOID PERSONAL INJURY.

8. REAR HVAC VEHICLES ONLY (RPO C34): OBTAIN LOCALLY A PIECE OF FLAT, GALVANIZED SHEET METAL (HEATING DUCT MATERIAL WORKS WELL), OR SHEET ALUMINUM, ABOUT 6" X 6" (150 MM X 150 MM). USING FIGURE 4, MAKE A HEAVY CARDBOARD TEMPLATE. USE THE TEMPLATE TO TRACE THE PATTERN ON THE SHEET METAL, THEN CUT OUT THE SHIELD. CREASE AS SHOWN TO ALLOW WATER TO DRAIN. SET THE PART ON A TABLE EDGE, AND BEND DOWN ABOUT 1/2" (12 MM), JUST ENOUGH TO CREASE THE METAL. DRILL FOUR (4) 1/4" (6.5 MM) HOLES WHERE SHOWN. DO A TRIAL FIT, AND SHAPE AS NEEDED TO PROVIDE CLEARANCE AND MAKE A TIGHT FIT TO THE FRONT SIDE. HOLD IN PLACE AND MARK THE FOUR (4) SCREW LOCATIONS. DRILL FOUR (4) 13/64" (5.0 MM) HOLES. ATTACH WITH FOUR (4) SELF-TAPPING GALVANIZED SHEET METAL SCREWS, P/N 12337828 OR EQUIVALENT. RE- CLIP THE REFRIGERANT PIPES IN PLACE.
