    • Smooth Performance and Excellent Build Quality
This ACDelco Gold idler pulley is top‑notch. Installation was straightforward, and it fit perfectly without any adjustments. The bearing runs smooth and quiet, eliminating the squeak I was dealing with before. The construction feels solid, with durable materials that inspire confidence it will last for years. I’ve put a few hundred miles on since replacing it, and the belt tracks perfectly with no wobble or noise. It’s clear this part is engineered to OEM standards, and I appreciate the reliability ACDelco delivers. If you’re looking for a dependable replacement pulley that installs easily and performs flawlessly, this one is a great choice. Highly recommend! ... show more

    • Works just fine.
Bought this for my 2005 mustang gt 4.6. Fits perfectly and works great. Same quality as the local auto parts store but a little cheaper if you don’t mind waiting a couple of days. I wasn’t in a hurry at all so worked out perfectly for me. Would recommend.

    • Acdelco part
Chasing a noise from the bad power steering pump purchased here, I let the internet convince me it might be a pulley, so I bought one of them here also. The pulley is good quality but wasn’t the problem.

    • OEM part for a good price arrived quickly
What I received was an original OEM part. For my 1999 Chevy S10 it fit perfectly, functioned flawlessly and took just 5 minutes to install. I found this part in the local part stores for 50 to 100% more money so I received good value for an OEM part from Amazon and it came right to my door in two days (quicker if needed). Note for some applications: your OEM pulley may come with a keeper washer that holds the bolt in place. This old keeper washer can be pulled off with pliers and discarded. It must have been some assembly aid when your rig came off the assembly line and it not essential for function - pull it off and throw it away if you find one in your case. For my 1999 Chevy S10, torque was 35 to 37 foot pounds. The Amazon 'fit guide' has been very reliable in my experience. Thanks to Amazon for supplying the right part for a fair price and delivering it to my door. ... show more

    • Silence is golden
I installed this pulley yesterday on my 01 Tahoe and replaced the 25-year-old pulley that had been up there since the truck had been manufactured. It had an annoying squeak when the engine was cold and that’s gone now I’m so happy it only took probably 20 minutes to install.
