Default Power Steering: High Pressure Hose

Guys,

I need a little assistance. I found a few topics on how to replace the actual Power Steering Pump itself.

I'm trying to replace my High Pressure Hose: http://store.gmpartshouse.com/parts/...iagram=CF97150

Part #8 in the diagram

Can anyone tell me how I can make this job easier? Looks like its down in the there...or do I have to pull the PS Pump, Suspension, etc...

Any help would be appreciated.

i used some 'crows feet wrenches' when i did mine. you will find that none or your box wrenchs fit bc of the confined area. I removed my driver side tire but prob didnt need to bc i think i got to both fitting from the top of the car. It is a PITA good luck

It is much easier if you drain the coolant and pull the water pump and throttle body. Also remove the alternator. From there you can get to all the bolts to pull the whole power steering pump assy out. The assy includes the power steering cooler as well. Whenever I pull that cooler I wrap it in cardboard. It keeps the fins from getting all mishaped.

The crow's feet are very nice to have. If you have access to a lift it's not that bad, you can do most of it from below. If the nuts are not too hard to break loose it's not a bad job at all. With a lift it took me about 45 minutes, didn't remove anything.

I'll borrow some crows feet today and apply some PB Blaster liberally as well.

I'll report back later.

I can jack the car up and go from the bottom if I find going from the top to be too much a bitch.

I'll make sure and throw some PB Blaster on there today and let it soak all day so it'll spin and come off.

I sold my DD the other day so I still haven't fixed this...the second I get a car that I can drive everyday, I'm tackling this.

I'd assume its metric...but again, not sure.

Finally tackling this...metric crows feet worked like a champ on the upper.

The lower proved to be a total *****...I basically took a sawzall and sliced it down to the bolt and then used a socket wrench to get it free before I stripped it out.

I'm letting everything drain and leak out over night. I'll tackle cleaning and installing the new one tomorrow.

For the lower you can get pretty good access if you lift the car and remove the drivers side wheel. You may have to remove the return first to get better access to the pressure fitting but it's fairly easy to access with open ended wrenches.

I pulled the return tonight.

Got in there good and did a clean...pretty nasty. The hose has been bad for awhile so cleaning took forever.

I slid the new line in, tightened the top down and ran out of steam.

Outta finish this up tomorrow. Just got the lower line and the return to tighten down and this little project is complete.

Ya, they make a mess. I used 2 cans of brake cleaner and a roll of shop towels to clean up my car.

Do you still have that month old high pressure hose and how much do you want for it?

I finally got around to changing the high pressure line. Nothing about the job was easy. The crows feet wrench did not help me. I did get an open end wrench on top end of line, there was no room to really move the wrench but with a crow bar I was able to get the nut to break loose and then turned it mostly by hand. I did this from the top under hood. The bottom end of the line was not that bad from underneath, again I did it with an open end wrench. Putting the top end of the new line back on was not easy getting the threads to catch and then tightening 1/8 of a turn at a time. Total time was about 4 hours. The good news is the leak is fixed.

Default photos of EPAS installation

I'm sorry this took so long. I hope the photo of my EPAS installation are helpful. I did it without removing or opening the steering box so I didn't need to re-center the steering wheel. Unfortunately this means I cannot be certain that the box is perfectly adjusted.

For this I'm preparing to bring my C1 to Jeff Reade in L.A. as he's highly regarded by the C1 community. Although he has no experience with EPAS and little interest in them, he's agreed to help me try to get my C1 to track straight, stop wandering, and return to center after turning. He'll be restoring the entire steering system from top to bottom and then we'll send the car to someone who's really good with alignments of C1's.

Hopefully this will eliminate the problems mentioned above and in my previous post above.
