How can you add an active grill shutter to my 2017 Chevy Full size van.

I see the 2017 and up GM pickups, Suburban, Yukons, etc have active grill shutter but the vans don't. I'd like to add one and would like some guidance. I suspect the one for the Suburban, Yukon, Tahoe may physically fit well... it looks like the radiators are the same height as the van.

active grille shutters

Look into all those vehicles to see if they have Messier variable-speed, electric water pumps.
These were in production as early as around 1991 on the small-block V-8 Cadillac, Roadmaster, and Caprice.
There would be sensors feeding signals to the ECU, which would modulate voltage to the pump. Shutters would need the same sort of electronic control, perhaps running in parallel.
And there needs to be a default, where the shutters fail 'open' so there's no chance to cook the engine.
