Looks good for a temporary fix. Watch you temp gauge.

For the permanent one consider a sheet of perforated stainless steel with a second layer that slides back and forth via a choke cable. With proper hole spacing, you could get ~75% flow with the holes lined up and ~25% with them overlapped.

I think you could probably cover the entire top grill. It depends upon how much of the bottom grill is covered by your license plate.

My top grill has been covered for over a year now and the engine temp seems to be typically about 4 to 6 degrees cooler than before I blocked the grill. I do have only a 2.3 L engine, but I also live in Florida. I appear to be averaging about 1 mpg better around town, about 1.5 mpg highway since making this change. Of course, subtle changes in driving habits may account for part of this improvement.

I was actually planning on cover the bottom grille entirely, so I think I'm going to keep the top grill the way it is. but then again maybe I might change my mind on that.

No update yet?

I believe another Ranger post mentioned blocking the top grill completely and keeping the bottom one open.

I just picked up a Ranger too. I4, 5spd. I'll be trying the above mod. Should have that taken care of next week. Also a front air dam, shortly.
And I'll be keeping an eye out for some hubcaps.
