You could do it several ways, first is set the outputs up one at a time as coolant and toggle the coolant button or you could set them all up as outputs then use the VB editor to toggle them, the VB for it would look something like this.
ActivateSignal(OutPut1)
Sleep 1000
DeActivateSignal(OutPut1)
What that would do is switch on Output 1 for 1 second then switch it off.
