Hello,

You must remove the serpentine belt to start and disconnect the battery. Here is a guide and a video to help you get the job done:

I have the power steering pump and was wondering if I need any special tools to get the pulley off or if I can do the change of a new power steering pump with general tools? I was just wondering if there was any specific tools that I needed to get before I started to tear it apart?

Yes, you need a pulley remover and installer. See if auto parts rent it.

Brother changing to new pump, making bad wining noise and is hard to turn, brother would like instructions on changing it, would also like to know if he will need any hoses that may not be included with new part? Has done many repairs to cars before but not to a newer car only 1980 and older any help would be helpful.

It looks like in either V6 configuration, it calls for pump pulley removal as one of the initial steps in removal. It does not say why, and the illustration is not detailed enough to show any reason. Removal of the pulley requires a special tool, a power steering pump pulley removal tool. It may be available at a rental store, or a parts store that rents tools. I would imagine it is a fairly common tool requested.

What type of puller are you using? A power steering pulley puller is not very large.

I have two illustrations, they are for the two V6 options. It looks like the belt routing is the same in both, I believe the illustration only differs with the engine picture.
The first is the 3.5, and the 3.9 is the following.

I just replaced power steering pump on my 2006 Impala. It is still making the whining noise and foaming in reservoir. I jacked up the car and moved steering wheel side to side hoping to rid air out of the system. After considerable amount of time it has not changed anything and I am afraid of damaging the new pump. Any suggestions? PS. It is making the same noise it was before replacing the pump.

It sounds like you have a defective pump that is pulling in air which makes the fluid have air in it and the noise will never go away until you redo the pump. May I suggest an AC Delco pump.

Here is a guide to show you what you are in for when doing the job:

https://www.2carpros.com/articles/how-to-replace-a-power-steering-pump

and you should flush the system.

Here are some diagrams that shows how it will be on your car (below).

Please let us know what happens.

Cheers, Ken

Jack wheels off ground put jack stands beneath vehicle. Start car and turn one way until end and hold for thirty seconds. Turn other way and repeat. Do this five times make sure of no leaks anywhere. Then see what you have.
