Wagoneer L6-258 4.2L VIN C 2-bbl (1982)
The valve is held in a normally closed position by a coiled spring located above the diaphragm. A special fitting is provided at the carburetor to
route ported (above throttle) vacuum through hose connections to a fitting on the valve which is located above the diaphragm.
A passage in the intake manifold directs exhaust gas from the exhaust crossover passage or from below the riser area to the EGR valve. When the
diaphragm is actuated by vacuum, the valve opens and meters exhaust gas through another passage in the intake manifold to the floor of the
manifold below the carburetor.
