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.
