Mounts on the top hose of a 2004 Colorado supercharged cooler with a modified top hose. Definitely recommend wearing gloves, the metal braids will make you bleed, I put two fingers in before I got any wiser. Doesn't like sharp turns, the top turn (closest to the radiator) seriously beat me. The item looks great but requires some creative work as the red bezel has no way to secure it to prevent rattling. I haven't checked the noise yet because the motor isn't fully assembled yet, but it's easy to turn by hand. Looks good, as long as I can stop the rattle I'm happy with it
