Fast Idle Valve
Description
To prevent erratic running when the engine is warming
up, it is necessary to raise the idle speed. The fast idle
air bypass valve is controlled by a thermowax plunger.
When the engine is cold, the engine coolant surroun-
ding the thermowax contracts the plunger, allowing ad-
ditional air to be bypassed into the intake manifold so
that the engine idles faster. When the engine reaches
operating temperature, the valve closes, reducing the
amount of air bypassing into the manifold.
