INSTALLATION
- Install evaporator purge solenoid (1) to body bracket (5). Make sure the tab secures the solenoid to the bracket.
- Install quick connect fuel tank hose (2) to evaporator purge solenoid (1).
- Install purge hose (3) to evaporator purge solenoid (1).
- Connect electrical connector (4) to evaporator purge solenoid (1).
- Connect negative battery cable, tighten nut to 5 N.m (45 in. lbs.).

It threads into the valve cover.
Scheme 36
When the engine is not operating or during an engine backfire, the spring forces the plunger back against the seat. This prevents vapors from flowing through the valve.
Scheme 37
When the engine is at idle or cruising, high manifold vacuum is present. At these times manifold vacuum is able to completely compress the spring and pull the plunger to the top of the valve. In this position there is minimal vapor flow through the valve.
Scheme 38
During periods of moderate intake manifold vacuum the plunger is only pulled part way back from the inlet. This results in maximum vapor flow through the valve.
