View Full Version : Power Steering Hose

Hi all,

One of my power steering pump hoses ruptured. It is the low pressure (return) side. I called most of the auto parts stores in my area and none of them stocked the low pressure hose, only high pressure. I checked AC Delco's website, which said that the high pressure hose could be used for both the high and low pressure sides.

Has anyone had this problem before? Are the two hoses interchangeable?

Thanks.

FMI:
This is for a '99 Alero 3.4L
The AC Delco part # for the high pressure hose is 36-365411, which looks different than the return hose currently on my vehicle. The return hose has a pretty radical "S-Shape" bend to it (I suspect for cooling), whereas the pressure hose is straight pipe directly to the R+P.

Happened to me in December/January. I think it was the same hose. The mechanic had it up on the lifts and I could see where the hose went into the rack and pinion leaking when under pressure, turning the wheel.

Anyways, stealership had to take off a motormount to replace the hose. I paid about $200, $75 for the hose I think.

Keep fluid in the power steering reservoir to keep your pump safe...if you have to drive it. I kept filling mine up before I drove it and only did that a couple days. My PS pump is still kicking.

Now onto my second LIM replacement in less than 20k miles. This time Im flushing out the dexcool and going all yellow Prestone.

Yeah, I blew mine at the race track once. The gasket on my headers where it connects to the flex pipe was leaking, and that happens to be right at the level of the power steering hoses, so it was shooting hot exhaust gas on them.

The pressure side is a hard metal line where it runs along the sub-frame under the exhaust. The return line is just a rubber line with crimped metal ends onto short sections of hard line with fittings for the steering rack and the pump. There is a short section of hardline in the middle of the line that loops under the car and acts as a cooler, and there is some silver reflective heat insulation around the rubber hose that runs below the exhaust. Although it's kinda flimsy it probably plenty for a stock car, but not enough for performance applications. Still, it's not as durable as the hard line so I don't know why GM made it a rubber hose down there in that section.


Anyway, from what I remember looking at it, the two lines sit kinda side by side, but the ports they go to on the rack and the pump are in different locations, and the hard line section have slightly different curves to them. I really doubt you could use a pressure side hose in place of the normal return hose. You can have them order one, or make a custom one like I did. Of course, I added an oversize cooler and used -AN fittings for everything, and you wouldn't necessarily need all that. You might able to rig something with some compression fittings for metal tubing and some cheaper fittings and hose. I'd use something more substantial than just some hose barbs and new rubber hose though. There is still some pressure in that line and you don't want it to blow. Here are some pics of my setup (off the car).

Jaysus no wonder why it costed so much ($600) to replace that PS line in the now totaled '95 GAGT!

should be able to just use some rubber fuel line since it's the low pressure hose. At least that's what I use at work. Granted, I've never replaced a PS hose in a Grand Am, but i've done it on plenty of other cars. Just pull off the old hose, bring it to the parts store, and they should be able to cut you a hose in the right length and diameter.

how does the top part of the hose that goes to the pump come off?
