Here's my version of an adjustable grille block. Hope it provides some food for thought.

Basically, two solenoids pull the 3 flaps to create an opening, hence providing sufficient cooling to the radiator. The sidewalls are there to provide an improved cooling efficiency.

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 ?
