Rated 1 out of 5 by VERY noisy from the box Very let down with this pump. Much noisier than the pump it replaced. Now to swap it out all over again.... December 9, 2016
Rated 5 out of 5 by Great Since install Tahoe runs and turns great no problems at all December 6, 2016
Rated 3 out of 5 by I am still testing it I needed a p/s pump. I knew Pep Boys for a long time, ordered one. Got it from the store; it was very noise. Exchanged it; the second one works better, still making noise, it's okay for now. Too much work to replace it again. I wish the quality would be better. December 4, 2016
Rated 1 out of 5 by Doesn't work properly This power steering pump doesn't work properly. December 3, 2016
Rated 3 out of 5 by Works fine. Needs EVO adapter if vehicle is so equipped. Had to buy a $50 EVO adapter as my escalade had this nuisance. I think any escalade/tahoe/yukon yrs 99-01 had EVO, then GM scrapped the part as you really don't need to electronically monitor your power steering fluid pressure... two day delay waiting for the part but works fine now.

Rated 5 out of 5 by nice working great November 12, 2016
Rated 5 out of 5 by Perfect replacement This pump was bought to replace an old leaking pump. All the parts needed were in the box. Followed the instructions and no problems so far. October 31, 2016
Rated 1 out of 5 by The first one was defective I order this part installed it and at idle I would lose power steering which was very dangerous I had to wait over a week to a replacement October 26, 2016
Rated 2 out of 5 by Good Price. Quality NOT so great My old Toyota truck has about 300,000 miles , the OEM pump finally gave up but didn't FALL APART ... just leaked. SOoo I installed this rebuilt unit because I was on a budget , and as a licensed mechanic I had installed HUNDREDS of these pumps in my vehicles and customers vehicles (I'm obviously not a NEWBIE).... only about 4 or 5 months pass by and the ENTIRE main-shaft and pulley blew out from the pump housing ... I AM GLAD that Pep-Boys has a good Warranty attached ... I am trying a Replacement for the failed unit ..... If it lasts more than a YEAR I will Rate MORE STARS next time. I HOPE sooner than later Pep-Boys will offer a BRAND-NEW option than just a rebuilt October 23, 2016
Rated 5 out of 5 by Great Product Great Price and product fits exactly perfect and performs to all expectations. October 19, 2016
Rated 1 out of 5 by pump was defective after putting on the pump it continue to have issues with the pump. The pump had to be replaced due to defection. Also 2nd pump did not have the seals needed for the high pressure hose. October 12, 2016
Rated 1 out of 5 by Failed after 1k miles Pump started to lose power after 1,000 miles. Steering was super tight at high speeds and had a complete loss of power steering at low speeds. Will not be buying remanned units from pepboys ever again. Wasted my time and money to install a faulty pump. October 10, 2016

Rated 1 out of 5 by ATSCO Remanufactured Power Steering Pump Not worth the trouble to remove and replace with this power steering unit... September 19, 2015
Rated 5 out of 5 by Worked great No problems October 29, 2015
Rated 1 out of 5 by This product leaks After spending all day replacing the power steering pump it started leaking when I poured fluid in it. I double checked the hose connection and found that it was the leaking from the bolt mounting the reservoir to the pump. In short this pump leaks worse than the one I replaced. October 18, 2015
Rated 4 out of 5 by ATSCO Remanufactured Power Steering Pump I'm satisfied with the outcome of this product, my truck now turns like a dream! September 26, 2015
Rated 3 out of 5 by Well it has good price The problems is that it is refurbished and sometimes they come with problems. That problem i have with the pump i bought, it is not working to good and probably ill have to take it out and pay the mecanic to cange it again. September 16, 2015
Rated 5 out of 5 by Pump working well Need to remove/reinstall the pulley from this pump, which requires the use of a puller/installer tool you can borrow from Pep Boys. After flushing the air, it has worked well for the past two months. So far, so good. August 30, 2015
Rated 5 out of 5 by one word "excellent" A more than good product and warranty exceed the expectations. August 16, 2015
Rated 5 out of 5 by quality at a good price I have replaced a number of power steering pumps in the last month. This pump came out of the box looking like great care was taken when rebuilt. There was no play in the bearing and was easy to work with. I had never heard of this brand, but I was amazed it was rebuilt, it seemed new. Seems like the company took the time to rebuild correctly. August 8, 2015
Rated 4 out of 5 by The product was a perfect fit!! I'm happy that the product was in stock. Finally, a remanufactured pump that works!! July 22, 2015
Rated 1 out of 5 by Power Steering pump The pump that I received started leaking 2 days after I had it installed. Had to get another one have it installed again and this one has not leaked. All of my savings went to labor. Having to pay labor twice. July 17, 2015
