This switch, Figs. 4 and 6, provides manifold vacuum to the air switching system after a cold engine start until coolant temperature reaches a predetermined level. After the coolant temperature reaches this level, the switch closes and vacuum is cut off from the air switching system. The CCEVS/CVSCO is mounted in the thermostat housing.
