Actuation
Check the thermatic fan annually.
NOTE: Dual control systems are required for automatic
radiator shutters and thermatic fans. Shutters must open
and fans turn ‘‘ON’’ whenever the intake manifold air tem-
perature rises above its sensor set point. Either condition --
high coolant temperature or high intake manifold tempera-
ture -- must activate the shutters and/or fan.
