I have been using 1AAuto for some time now and haven't had a issues yet. Their parts are reliable and they are at a good price. I had an issue with my fan Clutch on my 2003 Isuzu Ascended last Demember and repaired it with their part with no issues and with their free video instructions it made it very simple, took me about 45 minutes and I was done, I also love their life time warranty so you can't go wrong. Keep up the good work 1A Auto.

It doesn't work
Ok so my cooling fan clutch went bad on my 2004 GMC Envoy. Went to my local auto parts store and it was around $200 to $ 230.I went online and got one from 1aauto for less than $100 so I decided to buy it.well it didn't work,they sent me a second one didn't work by the third time my mechanic decided to get one from my local auto parts NAPA. And it work so I call 1aauto,and they are going to get my money back.So I try to save some money but it didn't work because my mechanic charge me every time he got the part in and out.

Great Experience
I came across 1A Auto while searching for a refresher video on how to change out the clutch fan. The video was well done, so much so, I ordered the part from them. The process was simple, with a good selection of options; the communication was prompt and factual; and the product arrived as expected. Over all the experience was great and would highly recommend 1A Auto to everyone!
