This fit exactly as the original and works fine.

Lasted 2 years, have to replace it.

Pump does not fit application

Make sure when installing to see where all bolts are . There is a 3rd bolt in back kind of hidden. But just time consuming to remove everything . But average person could do . Ps after install make sure to jack up car vehicle off his cap removed from power steering reservoir turning wheel left or right to burp the air out of the system or it can cause damage to the pump. I’m sure there is different ways to do but this is how I do it .

After a little work I got this pump to fit. The mounting points were a bit to big and I had to grind them down a bit so it would slide into place. It also does not come with new crush washers for the banjo bolt.. That is the reason for the 4 star rating. Pump is working with no leaks. I just re-used old crush washer and no leaks so far. Pump works well and was a great price. Hope it holds up. Install is a pain!

Very pleased so far with this pump, only have a week driving on it. At fractions less than auto part stores, I was skeptical about fitment from other reviews, but it fit perfect. Works great, nice to have low speed steering again.

Installed the part and has been working for 3 months now

Operates loudly!
