I just finished this job, let me share some more hard earned advice. 1st, use a crows foot with a ratchet if you can. I had an 18mm but not a 16mm for the bottom. For the bottom, you can use a long 16mm wrench to get leverage to loose the bolt. Then switch to short 16mm wrench for complete loosening and re tightening.

Now, be prepared for the pain because this thing is going to fight you on both sides. The new hose is very stiff and the rubber isn't exactly bent right to perfectly fit. When you go to thread the top part, it may be hard to line up the threads. What you can do is loosen the threads to the other metal PS line to the right, then push that out of the way. That will let you rotate the line to the right to get it threaded right, then you can straighten it back out so its parallel to the side of the car, and you can rethread the other line. Check the video from user Jim Dandy, he explains it more in depth.

For the bottom part – get under the vehicle and reach your left hand behind the plastic dirt guard behind the tires (you may need to loosen it, and also to not have big arms) and up over the long steering column thingy to grab the hose with your hand. With your right hand pull the nut down to expose the end of the pipe. Pull the pipe down and get the end of the metal line stuck in that hole. It will hold in place. It's still misaligned at this point. Now take your left hand and grab the metal pipe where it curves close to where the fitting is, and pull the pipe downward to line it up while using your right to get it threaded enough that you can let go with your left and carefully tighten it with a wrench. Make sure its turning easy and isn't cross threaded.

Wear safety glasses because PS fluid is going to be dripping into your eyes (ask me how I know this). You can wear gloves but you are going to get messy AF and have crap all over your arms.

On my 99 Yukon I didn't need to mess with the fan shroud, but the upper radiator hose was really in the way. If I had to do it over again I would remove that hose and at that point you probably should just replace it.

He skipped showing the hard part, they don't come with new clamp brackets and those are a nightmare to change, This video is a bit of a joke. I just finished changing one and it's not that easy.

Really appreciate you showing the hardest part, the bottom hose mount

Why y’all backwards it’s easier taking anything apart better

@pureflakmonkey3368 says:

Cool but you didn't show the hardest bolt removal at all.

@davidpetersen836 says:

Awesome video especially on the detail of how to get at the bottom fittings. Beyond believable.

What size is the bolt and what size wrench did you use ?
