I would like the flaps to be more distant from the opening, but most solenoids only have a reach of 1 inch or so. A linear actuator is a possibility, but its cost makes it a bit prohibitive for now.

Still haven't decided if the system will be automatic based on coolant temperature or fully manual. This is simply a basic conceptual drawing.

Any thoughts and/or suggestions ?

I think that looks something that might even work on winter, because you can build that without any other slides than the one on the solenoid.
