    Scratches and Dings right out of the box!
    I have yet to install this part, due to the fact it required a signature for it to be delivered via UPS on Friday and since i was working, i couldn't be there. it was then dropped off at a cvs on today which is Monday. That really irritated me since the weekend was planned around this install. Also, there already seems to be some scratches all over the tensioner. Pretty lame overall experience thus far.

    I simply needed a belt. But I followed the recommendations and bought tensioner and pulley and belt all in one. So I would say. If they offer you other stuff. Just get it. Same when I just needed a new water pump. I wind up replacing water pump and fan clutch and cleaned fan blades. So yeah do it all while it's off. I digress. The tensioner works great.

    Just installed it about an hour ago.

    Now, the belt and tensioner on the Colorado isn't the easiest, that's for sure. It's just so cramped in there. But, that isn't this part's fault.

    The Gates tensioner seemed to be every bit as heavy and sturdy and the one that I pulled off. And no, the pulley isn't plastic, not on the one I got at least. It was definitely a metal.

    I'll update if anything noteworthy comes along, but my initial impressions have been good.

    5.0 out of 5 stars GOT RID OF THE CHIRPING
    Reviewed in the United States on August 30, 2019
    Verified Purchase
    The springs in Gates tensioners are alot different then some of the other brands. They have several videos that explain that. I had a chirping problem and Gates recommends you change your tensioner along with the new belt. At first i just put the new belt on and still had the chirping. Got this Gates product and no more chirping. Gates says that the springs will rust inside the tensioner and thats usually something you cant see very good. I imagine that the tension applied gradually gos down a little bit as the tensioner gets older.
