I acquired a stack of corrugated-plastic "Vote for me" signs from my father in law and plan to make winter fronts for my truck.  How much of the grill do I need to leave open?

If its the grill you are blocking you can block it 100% and have nothing to worry about as it doesn't hardly make any difference blocking things there. If blocking the coolers and radiator then leave about a 6-8 inch opening in the center but this is totally dependent on how cold of temps you see and driving conditions, if you are pulling towing or town driving a lot..

Blocking the grill out will increase your IAT temps roughly 10-15*F giving a small boost to MPG.

 

Like Wild and Free said its based on local weather. Like me I can bounce between +40*F to -20*F in 50 miles of driving.

I'm way down south in Kanab, UT. I used the same thing, Voting signs. I pulled the grill section (I think 4-6 10MM bolts), proughly trimmed the sign piece for 1 side, held it in place, used the butt of a hammer to firce an indent line of the interior of 1 side. Then, with shears or a razor knife, cut it out. Test fit to be sure. Use as template for the other one. Spray painted satin black (Or whatever color you want, just didn't want the printing showing). Hold in place FROM CENTER with your hand & drill 6 sets of holes around perimiter (WITHOUT DRILLING THROUGH YOUR HAND) & zip tie in place. Put on in November & removed in March.

 

Much better use for voting signs than promoting a bunch of crooks.

Like Ed said for the most part I agree but I have a bunch of Ron Paul signs I just couldn't deface like that.

How about that...great minds think alike all the way up here in Canada.

I slipped a vote for me sign between the radiator and charge cooler after I cut out an 8x8 hole in the middle. 

 We don't seem to get the cold here that many of you get and I was a bit nervous of overheating. 

Never got above 200 just got there quicker.

This year I am driving a beater jetta as much as possible instead of the truck, trying to keep it out of the salt.

But Snowshovler, if you do it that way, your A/C won't work good...LOL

Thanks for the replies.  I'll knock it out this weekend.
