Arrow Help with power steering pump/belt issue on 00 SS (pics)

Was driving my parents 00 SS to a job interview and right as I go to turn in, the steering makes an awful squeal and feels as if the p/s went out. I pop the hood to check it out and see belt jumped the pulley, and is partially spinning on the plastic P/S fluid housing, which has frayed the plastic open and is throwing p/s fluid all over.

Im a little perplexed at how this happened, as I'm an amateur mechanic at best. 14 years old but 18,100 miles. It looks like there's a 'bolt' missing in the center of the pulley. I'm able to spin the spindle by hand so it's not locked up.

I'm going to attempt to fix this myself. What im asking - is there anything I should specifically look for/at, is this a common problem or just an isolated issue? It looks like I'm going to need a new pulley and plastic p/s tank at the least.

Thanks for any input.

Any help? thoughts? It looks like the resivour and pulley need to be replaced. Im hoping it CAN be replaced and the pump isn't bad

Re: Help with power steering pump/belt issue on 00 SS (pics)

I have exactly the same problem but cannot find any resolution in any of the threads about power steering pumps. My car is an 02 Z-28 with less than 10K on the clock and when I fired it up this morning, I head a "clunk" so immediately shut it off, popped the hood and found the belt (in one piece, no signs of wear) just laying against the p/s pump. Looks exactly like the picture that's already been posted, p/s fluid everywhere. Pump, and idler spin free. Now what, coaches ?

Help with power steering pump/belt issue on 00 SS (pics)

Although I can't explain the ps fluid all over, looks exactly like what I fixed a couple weeks ago on my ex wife's GM van.. The pulley broke and the metal center of the pulley is still on the pump.. I was able to rent a ps pulley puller/installer tool from autozone and pull what was left of the pulley off the pump and press a new pulley on the pump with it still in place on the vehicle... I think you should be able to get away with installing just a new belt and pulley as well... Can't say for sure if you will need to get the pump out of the car to do this, it depends on how much clearance you have to work with with the tool I mentioned.. It appears that the new pulley you need is GM part #12559885, if you search ebay for that part # you should be able to find a pic of one that is still intact...

Re: Help with power steering pump/belt issue on 00 SS (pics)

I believe the stock power steering pulley is pressed on the power steering shaft. From the looks of the picture, the pulley's hub was crimped onto the pulley shell. Perhaps the failure was inherent to the poor factory manufacturing of the pulley allowing the fit between the hub and shell to become week over the years. I also believe that the fluid leak may be attributed to the pulley wobbling for a while (perhaps mant days before it finally let go all together) and contacting the plastic power steering reservoir rubbing a hole in it, not the belt. Hopefully over the last 14 years parts manufacturers have tightened up there standards a bit and your replacement parts will serve you for many miles. I wouldn't think anything else caused the issue other than the poorly made pulley. Good luck

Looks like a bit of work there. You may have to remove the power steering cooler to get more room to work. To help, you can download a free 2000 F-car service manual here: http://www.mediafire.com/?40mfgeoe4ctti
I agree with "Cam's maro"'s analysis above.

Re: Help with power steering pump/belt issue on 00 SS (pics)

Thanks to everyone who commented and thought I'd get back to the group to hopefully shed some light for the future.

Even though my car has very low miles, (less than 11K) it is still a 12-year-old automobile that has not been driven much and age of components is a factor. Coupled with that the design and composition of the power steering pump and pulley are less than desirable for almost any application where more that about 200 HP will be used.

While GM V-8 applications use a 6-groove pulley, the four-groove pulley used on 4 and 6-cylinder cars is basically the same pulley as other than the top groove width to accommodate the 6-groove serpentine belt and the accessories it must run, the diameter of the pulley and the fiber-thermoplastic composition are the same. Add to that the practice and method of robotically pressing a fiber-thermoplastic pulley on to a serrated shaft with the potential of applying robust engine torque at low RPM and it appears to be a formula for failure.

Since everything else seemed to be okay, I contacted Junior with Turn One and picked up one of their pumps with the aluminum pulley pre-installed. It arrived in two days, took about an hour to install and a 16MM flare-nut wrench is indispensable when removing/installing the high-pressure power-steering hose.

Again, thanks to eveyone..Illmanners..

Re: Help with power steering pump/belt issue on 00 SS (pics)

Thanks for all who took time to respond. For some reason it didn't notify me via email about the responses.

I ATTEMPTED to replace the pulley today, and after a few hours and frustration with GM and their s*** designs, I think Im just going to order a different style pulley so I can install the pulley with the PS pump OFF the car, then install the entire pump again vs having to install the pump, then press the pulley on with 4" of space.

First off, the radiator hose is in front of the pulley, so had to take that off. and this stupid plastic clip holding the radiator hose is directly where you have to put the pulley puller. I'm not sure if it's the amateur mechanic in me, or what... but for the life of me I couldn't get that pulley puller to push the pulley back on. Between the cramped space, everytime I tried to get it on, then clamp down, it never pushed it on. I despise the 'pressed on' design.

On top of that, I noticed on the new pulley there's a small chip on the BS plastic pulley, typical crap material GM puts on their cars (no wonder they are almost bankrupt and kept having to recall their cars )

Don't mean to come off like an a-hole or anything... just very frustrated. Obviously I'm doing something wrong... but it doesn't SEEM like I am. Now that I see this crack, I tihnk it's easier to just buy the other pulley and put it on while it's off the car

If you look where the shaft is, you can see the plastic clip that makes working on it that much more aggravating.

Virtually every PS pump pulley I have ever changed, on many different manufacturer's cars, has been pressed on. This isn't some GM subversive plot to screw up the world.

I haven't done a lot of PS pulley, but I can say the other one I did (nissan maxima) was secured by a bolt instead of pressed on. It came with it's own difficulties, but one of them wasn't that frustrating "pressed on" mess.

I thought a lot of foreign cars don't practice the "pressed-on" method, thought that was more of an american car thing. Maybe not..
