    Blown High Pressure Power Steering Hose

    Alright, I was working on the 91 GP today, and when I pulled it out of the garage after changing the oil, one of my power steering lines burst so there is PS fluid everywhere in the parking lot lol. And after driving it about 100 feet and putting it back in its parking spot, the reservior is nearly empty...

    I don't have a jack, jackstands, or ramps with me, so it is really hard to tell where it was leaking from (and made changing the oil really suck.. that is a tight fit!). It sprayed fluid ALL over the backside of the engine I slid under the car and can feel where a line comes off the rack and turns to rubber for about 4 inches, then it is metal again, it is really wet here.

    Where and what are the common PS lines to go bad on these? It is not rusty at all, being an AZ car, the underbody looks like a new car. I think one of the rubber PS hoses somewhere burst. It isn't wet at all near the pump, and the hoses on the passenger side of the engine look to be dry. It is very wet in the center of the car. Near the rack, it is completely dry.

    Any ideas guys?

    Hey man, I'm gonna take a stab at it and say its the cooler line. At least that's the one that spewed on my Euro. It's a hard line that runs parallel to the rack for about 12-14 inches, does somewhat of a *90 bend (this is where its a rubber line, about 4-6 in. long with crimped collars over the metal line), and then turns back into a hard metal line as it does the loop and doubles back off of the front of the cradle. Easy fix if this is it. Hope this helps you.

    I think that is the one. The 90* rubber bend is the part that feels really wet. I'm going to need to get the car up in the air so I can see it better though. How much is it to replace the line? Difficult to do?

    Re: Burst Power Steering Hose... 91 GP

    Can the rubber 90* bend be replaced by itself, or is it part of the hard line? I can't see very well under there.

    In this picture, it looks like the rubber piece is held on by a couple hose clamps, is this right?

    Thanks

    The cooler line always blows out right there on that rubber section. A lot of members have had that happen. My old Lumina Euro is on it's 3rd one. And no it's not held on by clamps. It's crimped onto the metal lines. So unless you want to cut out the section and splice in new hose (which isn't a good idea) you have to buy that whole line in your picture. It's not all that expensive. I think maybe 40 or 50 bucks at local autoparts store IIRC.

    It does kind of suck to change it. It's not difficult though. You can do it in the garage on ramps with some hand tools, but it's time consuming because it wraps around the engine and attaches in hard to reach places.

    Hmm.. I'll have to see how expensive it is, I don't have much money at the moment. What would happen if I cut it and spliced in some new high pressure hose in its place?

    Unless you flare the ends of the line look forward to it coming undone down the road. I tried that with a transmission hose, it didn't last.

    Re: Burst Power Steering Hose... 91 GP

    I just looked it up and they are only $25 for a new one, so I'll just replace the whole thing with a new unit.

    Is there a writeup for this somewhere, or are they really simple to replace?

    Re: Burst Power Steering Hose... 91 GP

    This happened to me last year - and I cut off the rubber section and put in a piece. After a few failures (read: shit hose) I haven't had any further problems.

    If yyou go that route thouh use fuel line clamps as they won't cut or damage the hose and they can take some good torque without stripping.

    Here is my link from last winter: It's got some pictures and bullshit in it

    http://www.w-body.com/forum/index.php?topic=65857.0

    Since that thread ends on a sour note - my 7th and final repair was to install the fuel line clamps, put a new hose on, and use AC Delco "COLD CLIMATE P/S FLUID!!!" <--that stuff is fucking amazing. I highly recommend it.

    X2 on his repair method. I did it over a year ago and had to do it again a couple months ago, ONLY because rubber hose that isn't pre-formed in a 90 degree bend, doesn't like to be bent that way and stay without leaking . SOOOOO, I just took some new hose (that I had leftover from the first time), and did a loop-de-loo with it. It's holding up just fine. Hasn't leaked or blown lines off (knock on wood). If the whole new cooler line is only 20 something for you, it may be more cost effective do replace the whole deal. When I did it, to local Auto Value had it for almost 60 bucks, versus 10 bucks for some generic PS line. So, I went that route since I was pinching for pennies, (broke college student still), and since it was just on my Euro. Whichever way you go, have fun. It's not too bad to replace.

    Re: Burst Power Steering Hose... 91 GP

    Well, I'm glad to hear its an easy job and not horribly expensive. I am also a broke college student.. lol

    I need to find a way to get the car in the air so I can confirm that it is in fact the low pressure line leaking.

    Is there anywhere else near there that I could have a leak?

    The high pressure hose is just above it - it too has a rubber piece that I think can be seen in my picture.

    There was no jobber low pressure line that I could even buy around here - and I think the GM one was over $100...I too was broke in school last winter.

    Re: ... OR NOT?!

    I don't know why I didn't think of this earlier... I grabbed the factory jack out of the trunk and jacked the car up... The low pressure hose is definitely NOT leaking. Let me draw a picture here. There is the metal shaft (intermediate shaft?) going across to the passenger wheel, just above the low pressure line. On this shaft, above the low pressure line, there is a fitting screwed into the shaft. I went and turned the wheel back and forth a few times and scooted under the car, and there was tons of orangeish foaming fluid oozing out from around the threads on this fitting... what is this? I'd imagine I can just tighten it, couldn't I? Leaking around this fitting would explain why fluid sprayed EVERYWHERE

    Couple pics: You can see the leaky fitting in the second pic on the lower right side, there is orange ps fluid seeping out around the fitting.. kinda hard to see until I got in the car and turned the wheel a couple times, then it went foaming everywhere.
