Not a stupid idea. Upper grille blocks from my following of others experiences along with my own seem to be more effective. If your in a cooler climate it's a great idea. It will reduce warm up time immensely. Also really depends on your vehicles. Time of year may also dictate whether u can use it as well if your in warmer climate. Always make it easily removable and have a way of watching your temps other than the dummy guage on the dash. Right now where I live temps are in the 70s by 10 am typically. Been in the 90s and I have had no issues with my grill block. That in itself is due to the fact I only did a partial block. Will do more in winter months. Anyways vehicles are developed to be able to keep themselves cool in the worst case scenario. Like driving up a 20° grade in death valley pulling a trailer. Maybe a bit excessive but you get the idea. If your driving ecomodder style you should be able to get away with at least a partial in any climate.

Same here. It *might* be helping, especially in the winter, but so much else has changed since I started getting serious about MPG.

I took all of my grille blocks off a few weeks ago because it wasn't taking long to reach operating temp and trip the radiator fan at 90-100°F ambient. Back to focusing on driving techniques to eke out gains until it gets cold again...

Welp, my grill block (lower -- there's only a small slot below the hood left for air flow) didn't cause me any issues yesterday, when it was 90-something degrees. Temp gauge never moved above it's usual half way mark. Nor did it on a highway climb up the mountain to get out of this town a couple of weeks ago. This is on my Firefly.

The cooling fan comes on when you stop moving. And it certainly aids warm up time the rest of the year!
