Fall and spring are the times of year when I often have to check the forecast to decide whether to drive with a full or partial grille block. The full block warms my car up quickly, but any trip over 5 miles on a warm-ish day causes the radiator fan to cycle on and off for the rest of my trip. Not ideal. The lower grille block I've been using is held on by the license plate, so it's not horrible to remove, but it could be more convenient:
I love the threads here on adjustable grille blocks that are controlled by Arduinos, choke cables, thermostats, wind speed, and what have you, but I'm far too lazy to see one of those projects all the way through.
So here's what I just made: the lower grille block has large windows cut into it for warmer days, and Velcro-clad squares can be stuck on for colder days:
With the squares off:
And squares on:
Should be just the thing for cold mornings paired with warm afternoons, or groups of errands.
