REMOVAL: Detach the vacuum line(s) from the EGR valve. If there is more than one line, be sure to label them to assure proper installation.
Unfasten the two bolts or bolt and clamp which attach the valve to the manifold, then remove the valve.
Make sure the old valve gasket is removed from the manifold.

INSTALLATION: Thoroughly clean the gasket mating surfaces of the valve and manifold.
Install the valve to the manifold. Always use a new gasket between the valve and the manifold.
Install and tighten the valve retainers.
Attach the vacuum line(s). On dual diaphragm valves, attach the carburetor vacuum line to the tube at the top of the valve, and the manifold vacuum line to the tube at the center of the valve.
