Installation of A Vacuum Reducer Valve
INSTALLATION OF A VACUUM REDUCER VALVE ON A 2.2L-2BBL ENGINE EQUIPPED WITH THE NYLON VACUUM HOSE HARNESS (1983 M.Y.)VACUUM REDUCER INSTALLATION PACKAGE PN 4293794
PARTS REQUIRED PART NUMBER
1 - Vacuum Reducer Valve 4104184
1 - Connector, In-Line (.15 nylon to 4179391
3/16 rubber)
1 - Connector, Elbow (.15 nylon to 4213774
3/16 rubber)
1 - Tee 4104172
INSTALLATION PROCEDURE
1. Carefully cut the tape around the vacuum harness convoluted tubing at the end closest to the coolant switch.
2. Peel the convoluted tubing away from the nylon tubes and cut 2" from the front of the engine clip that mounts the vacuum harness to the air pump pulley cover. Discard the cut piece of convoluted tubing.
3. Locate the nylon vacuum tube running from the CVSCC (CCEGR) coolant switch on the side of the water control box nearest to the white dot on the connector.
4. Cut the tube located in Step 3 2.5" from the CVSCC and 2.5" from the vacuum harness mounting clip. When cutting the nylon hose, use a sharp razor so the hose won't kink. Discard the unused hose.
5. Install the small end of the In-Line Connector, PN 4179391, on the cut end of nylon tube closest to the CVSCC. Install the small end of the Elbow Connector, PN 4213774, on the cut end of nylon tube closest to the harness mounting clip. Orient the elbow connector such that the 3/16" end is pointed toward the CVSCC.
6. Install the Vacuum Reducer Valve, PN 4104184 (white nipple), between the connectors installed in Step 5. Position the vacuum reducer valve such that the third nipple points downward.
7. Locate the blue striped vacuum hose in front of the carburetor.

8. Cut the blue striped hose 2.5" from the air pump pulley cover, approximately in front of the air cleaner mounting bracket, and insert the Tee, PN 4104172.
9. Cut an 18" length of 3/16" rubber hose (Bulk Stock PN 3780507) and install on the tee. Route this hose over the valve cover next to the air pump pulley cover. Between the engine and the vacuum harness loop the hose approximately 2.5" from the vacuum reducer valve and connect to the remaining nipple.
10. Tape the four nylon-vacuum tubes together at the edge of the in-line connector.

PART NUMBER
1 - Vacuum Reducer Valve
2 - In-Line Connector 4104184
1 - Tee 4241296
4104172
INSTALLATION PROCEDURE
1. Cut two 1.5" sections of 3/16" hose (use Bulk Stock PN 3780507) and install on the white nipples of the Vacuum Reducer Valve, PN 4114184. Install the in-line connectors on the hoses with the large end to the hose.
2. Cut one 8" length of 3/16" hose and install on the remaining nipple of the vacuum reducer valve. Install the Tee, PN 4104172, at the other end on the 8" hose.
3. Locate the orange striped hose connecting the vacuum amplifier in the vacuum solenoid. Cut this hose 2.5" from the solenoid and install the tee of the vacuum reducer subassembly.
4. Locate the vacuum hose, harness bundle running along the inside of the valve cover. Cut the yellow striped hose midway between the two tape wraps and install the vacuum reducer sub-assembly.
