Seth Patterson –
Works good. Air conditioning belt.
P. Christopher Heffernan –
My original GM belt went 18 years 174k miles. I tried to buy the original GM OEM belt again, but Amazon couldn’t ship it for a few weeks. My old belt was so bad I didn’t want to take a chance going on a trip at the end of the month, so I bought the 2nd best thing. AC Delco aftermarket, fits properly just like the GM belt did. No squeals. Likely the last AC belt I will ever change on my 2005 GMC Sierra 1500 SLE 4X4 5.3L B engine.
Larry Gow –
Great fit. Perfect
Mr. T –
I purchased this belt to replace the A/C drive belt on my 2005 Suburban (note that the larger serpentine belt for all the other accessories is a different part #). The original belt was dry, cracking and about to break. This one looks to be plenty durable and well made.
This was a pretty easy job, though since you have to remove the primary serpentine belt to get to the A/C belt, you may as well replace both at the same time. And replace both tensioners while you are at it, and possibly the idler pulley as well if it is at all questionable. There are good videos online on how to do it.
