ACDelco Gold 38001 (88909582) Idler Pulley

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!

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.

Great item, works perfectly and easy to install,A++++++

Did great and quite for a daily/long distance drive vehicle. Had no issues with it after 10k miles and would buy it again if my serpentine belt layout wasn’t modified now.

Works well, same size / perfect fit. I also purchased a bodeman to replace the lower idler pulley. I think the bodeman is a little nicer / bearings seem a little smoother, but that was not available for this when I purchased. Thus 4 stars for this instead of 5.

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

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.

Este producto cumplió con las expectativas, quedó bien en Chevy S10 1998, el producto decía que no era nuevo y venía en caja abierta pero en realidad cuando llegó estaba nuevo y en un precio casi regalado en comparación de comprarlo en AutoZone
