How do i replace a power steering pump pulley on a 2000 chevy malibu 3.1L?
GM power steering pump pulleys are a pressed on type with an"interference" fit-the hole is .001" smaller than the shaft.You need a puller/installer tool.I bought one for about 30 bucks at NAPA,you might be able to rent one at an auto parts store.The tool clamps the pulley nose and has a screw to push the shaft out.(some Chrysler alternators use the same design).

This can be VERY expensive I would first contact GM customer assitance the phone number should be in your owners manual.Maybe depending on your milage they will split the cost with you.I worked 20 plus years for GM and they helped alot my customers.
SOURCE: i first heard a squeek then when i was parking steering got hard i checked fluid its full
Same thing happened to me a week ago... I was parallel parking and my power steering locked up.
My car ran fine, however every time I braked and turned simultaneously, the steering got hard.
I took it into the shop, it needed new power steering pulley parts.
On my way to the shop however, my car started chirping.. it also needed a new serpentine belt (I'm not sure if the problems were related).
Both repairs together cost me under $200.
Hope that helps... (by the way, my car was stable enough to drive the 25ish miles to my work before I got it fixed... I'm not sure how safe that was, though)

Does your van have the serpentine belt? If so maybe I can help, I replaced the Power steering pump on my 90 G20 a couple of weeks ago. The trick is that you need to pull the pump pulley which is pressed on to access the mounting bolts which attach the pump to the engine. Harbor Freight tools sells a great tool designed for this job for $20.00. Once you have the correct tools, remove the serpentine drive belt. You may also need to remove the fan shroud. the pump shaft looks like it has an allen socket in the center, but this is for use in the manufacturing process, and will not come out. Place the puller tool on the pulley following tthe instruction that come with the tool, and remove the pulley. loosen, but do not remove the nut on the high pressure hose connection. use a pair of **** pliers to cut and remove the crimp clamp on the low pressure hose. If your pump has the remote reservour loosen the clamp on the reservour hose also. Remove the three mounting bolts, place a large pan under the pump to catch drips, and remove the prevously loosened hoses. there will be fluid leaking all over and the pump should come free, There are two types of replacement pump sold. With and without reservour. This reservour is a metal cover that fits over the back of the pump, and should not be confused with the reomte revervour found on some newer models which is next to the battery. This reservour is held in place be two throught the pump bolts which are removed at the back of the pump. If your new pump has a reservour you will probably still need to remove these bolts and put them in the replacement pump as most are shiped without these bolts. If you replacement pump comes without a reservour pull the bolts, the reservour should pull off of the old pump and slide onto the new one. check the o rings and replace the through the pump bolts. Installation is the reverse of removal execpt that 1/2" hose clamps replace the crimp clamps on the low pressure hose, and the puller tool is set up differently to replace the pulley. Finally if you don't flush contaminants out of the system your repair will last maybe a week. www.cardone.com has a great article about power steering flushing, read it before you start Good luck.

You're going to have to bleed the system alot on those trucks. Just remove the return line and have an assistant turn the steering wheel back and forth just enough to engage the pump and filling the resevour while doing this. Keep bleeding until you have a good flow of P/S fluid out with no air bubbles. This can take a while.

It could be done at home if you bought the proper tool to remove and replace the pully on the pump.They do give you some sort of a tool with the new pump but I find it really weak and they brake leaving you stuck.This is why I say"If you bought the proper tool".
Testimonial: "THANKS YOU HELPED ALOT"
1. Remove serpentine belt
2. loosen power steering pressure and return hoses
3. Remove nut from pressure line mounting on alternator bracket
4. remove power steering pump mounting bolts.
5. Lift pump assembly from engine mounting and remove hoses.
6. Reverse order to install. Fill and bleed system.
NOTE: A new or rebuilt power steering pump will most likely not come with a pulley attached. You will need a power steering pulley remover/installer tool to transfer the pully from the old pump to the new one.
