The Big A## Air Dam currently has no openings in front of the radiator, and I have also blocked off the mail slot between the hood & bumper:

This was all fine and dandy when temps were truly frigid, but I noticed yesterday the cooling fan was coming on in -8C temps while cruising between 75-90 km/h (47-55 mph) at 50-65 MPG US.
It wasn't serious - the fan would run for maybe 5-10 seconds every 2-3 minutes.
FYI: fan trips on at 204 F, shuts of in the high 180's.
I'm going to have to come up with a variable block as spring approaches. We are right now in the statistically coldest time of the winter --
Jan 18-20 in this part of the world -- the
dead of winter. it's all downhill from here!
