power steering pump lines
I have 2006 LQ9. The power steering pump has 3 lines. 1 high pressure & 1 return. What is the 3rd line? Is it for the hydroboost? Can I just cap it? If so, how do I cap it?
Thanks

I believe you are correct. Hydroboost. I think people do just cap them. Try a " SEARCH" its been discussed MANY times before. Sorry I couldn't help more.

Yes my PS pump had three ports: a metric fitting on the bottom for high-pressure, and two 3/8" hose ports on the side for return, originally meant for one from the steering rack and the other from the hydroboost. I originally used one for return from the steering box and then blocked the other one off by hose clamping a 2-inch long bit of 3/8" hose with a 3/8" bolt in the end of it, with a hose clamp clamping the hose to the bolt threads. I've since decided to include hydroboost so all the ports will be used up.
Cheers,

I haven't fired mine up yet but I do need to cap off the 3rd line. I was thinking about threading it with a tap, screwing a bolt in and use some thread sealer. My 6.0 is already in my 72 GMC truck so I don't want to borrow the pulley tool and switch pumps. What do you think?
