Review on ACDelco 88963473 Power Steering Pump Kit: Genuine GM Original Equipment with Retainers and O-Ring by Dean Gomatham

Gotta love Revain. Needed a horsepower pump for my 2005 Terraza that costs 130,000 and now every part turned by the serpentine belt has been replaced. The local auto parts dealers only dealt with repairs. This new block was basically the same price. Borrowed a PS puller from a local parts store and replaced it with no problem. Accessing the pump on the Terraza is the hardest part. It comes with an o-ring for the liquid reservoir but no o-ring for the high pressure line. I used a green viton o-ring for a conditioner (I had a box of these) and it worked fine.
