    3.1 liter?

    If so you will need a 13mm socket to remove the three bolts that hold it to the timing cover. Before you remove them break the High pressure line fitting loose. I think its a 16mm. Line wrenches work the best to do this. The low pressure hose should be help on with a squeeze clamp.

    Once the high pressure line is loose you can remove the 3 blots. Then remove the high pressure line and the low pressure line.

    You will then need a power steering pump puller kit so that you can swap the pulley from the old one to the new one. If you don't have one or don't want to purchase one you can bring the pumps to any auto shop and they should be able to transfer them for you for a nominal fee.

    Once you have the new pump installed fill the reservoir with P/S fluid. Start the car and shut off as soon as it starts. Recheck the fluid level and add if necessary. This will keep air bubbles to a minimum. once the level is adjusted start the vehicle and let idle while you move the steering wheel back and forth a couple times making sure to keep an eye on the fluid level. Check for any leaks and you should be good to go.

SOURCE: 1987 Chevy G20 van replace power steering pump

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.

SOURCE: illustrations of removal of power steering pump on

Here is a good link. Check out the video. Changing the pump is a pretty simple task, especially if you bought the pump with a new pulley. If you only have the pump you will need a pulley removal/installation tool. Check your belts to see if they need replacing because now would be a good time to do it since they have to come off to take off the power steering pump.

Replace power steering pulley on 200 chevy malibu


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).

I dont know where it is


it is located behind the power steering pump. You need to remove the power steering pump to get to it which requires removing the engine mount next to it to get the bottom bolt out of the power steering pump. The sensor is directly behind the power steering pump. You can follow the cable that goes behind the pump. It is the only one there.
