Is there any appreciable cooling loss when the front bumper valance (air dam, hangy-down-under-the-bumper-thingy, ...) is removed? Mine has been deformed over the years and don't really care about "fog" lights (and I can see the clearance advantages!). I appreciate your thoughts and knowledge, Russ

 

a lot of guys have taken it off or trimmed it, not much advantage that I can see to leaving it there, It's not like you can help the gas mileage with it much.....lol

 

I'm hoping that it won't affect it's cooling - I'm just remembering GM vehicles I've worked with that even they're little "air dams" made a noticeable difference in cooling.

I suppose I'm about to find out, though - there are enough loose/missing screws and clips under there that it bugs me. Seems to be the only rattles on this truck (so far!). Russ

 

These are flat faced fronts, the radiators blunt to the wind. If anything you'll be increasing the cooling (bottom of radiator not the top does the majority) not decreasing it. Get the fugly off the front.

 

Everyone who has done a off road bumper threw that part away, its for looks, then cut off the bottom of the bumper caps, one of those vibrating cutters is perfect

 

I'm cutting it off! Thanks for the input! Russ
