Guys, good afternoon. My power steering pump gave away, so i bought a pump in advance auto but it didnt come with pulley. So we are trying to remove the old pulley, but we cannot do it. Do you have any suggestions how to do so? We tried different pulley removal tools but we have no success. The pulley does not have the gap to put the pulley removel tool and they dont sell the pulley for the pump either. Its for an aveo 2008 LT sedan.
Any tips or help will be appreciated.
Thanks in advance.
That's the serpentine belt, and it gets removed by relieving pressure at the belt tensioner (separate belt loop component).
Thanks, but we already removed the pump, we need to takenoff the pulley from the pump. Any suggestions how to do this? We tried different pulley tools but didnt work..
Got a picture of the old pump with the pulley on it?
I would think there would be room to put a bearing puller on it.
Cheers
How can I upload files, I cant.. :( ..
Here are the pics:

Sorry, I read your OP too quickly and thought you were asking about removing the belt.
I've never had to do anything with that pulley on mine, and the service manual only says "remove the pulley bolt", which obviously is of no help. However, they didn't mention needing a special tool, and it also doesn't look like the standard PS bolt setup. So that makes me wonder if this bolt just gets undone using an inserted tool (hex wrench, etc), while pinning the pulley by passing a bar through one of those holes in the face of the pulley. Do you have anything in your toolbox which is an exact fit into that pulley bolt?
I tried .. no luck.
Well this is quite a mystery, and obviously a PITA for you. I tried a number of searches (which I'm sure you did as well), and can't find any information on how to remove and install this pulley bolt. That's strange, because there's almost always some information floating around in cyberspace, particularly if something is difficult to do.
With nothing else to suggest, how about Chevy stealerships in your area? Bring the pump to the parts (not service) counter and see if they might be willing to help you out with that information. And, if the counter guy doesn't know the answer, ask him if any of their techs would be willing to answer a simple question like this. Doing something like this is a crapshoot, but you might get real lucky if there happens to be a decent group of people working there.
I wouldn't try calling on them phone about this. It would be too easy for them to blow your call off, and IMO you have a much better chance if you bring the part in, with a totally defeated look on your face (no problem with that, right?). And perhaps rub some oil and dirt on your face, if it's not already there.
Excuse my ignorance if I have this wrong ��.
From the pic’s there appears to be a pulley and housing, from the pulley side the inner shaft(part of the pump) has a recess which I assume held a mounting bolt (so the inside is threaded).
Now that the bolt is removed you need to install a longer bolt and put a 3 clamp big a$$ bearing puller (on the out side of the pulley or you can use the notches) to pull the pulley away from the pump shaft.
You just want to be careful to not distort the pulley (since these two will have chemically welded/oxidized). Heat or liquid wrench should help. For a longer bolt, try an Allen cap screw of the same thread, but make sure you use a screw because the pointed end of a puller would likely expand that inner shaft and impede what you are trying to do.
For installation, again with a longer bolt and some shims, start the pulley onto the shaft and then tighten the bolt, when it bottoms out at the thread you will have to add more spacers or change to a shorter bolt, but this will give an even pressure across the circumference and make sure the pulley isn’t going on skewed.
Cheers
No, the pic from the OP shows the pump as it came off the vehicle, because the pump that's on my Aveo right now looks exactly like the one in the pic, with no bolt occupying that space. With my curiosity level way up, this afternoon I used a mechanic's mirror to look down that recess. The recess is over an inch deep, and it looks like there's possibly something down there that could take a bit. But it just doesn't seem like that could be the head of the bolt that holds this pulley onto the pump. I'm sure this 'bolt' is really mechanically simple, but without seeing it in action it remains a mystery.Quote:

The AC lines are obstructing any view but from what I see on Rock Auto/Auto Zone that have pictures of this pump.The shaft is an integral part of the pump assembly so the pulley is just a press fit onto the pump shaft.
It may be possible to install a shaft into the recess (with a small center hole to guide the puller) and separate using heat/penetrating oil and being careful not to distort the pulley.
However , reassembly is going to be more difficult and probably both tasks would be better if you have access to a press.
If I was stuck without some of these tools, I would drill out the inner shaft being careful to not catch the actual pulley.At that point it should be easily removed and cleaned up to its actual inside diameter. Then tap the new pump recess to the closest thread size and use bolt and spacers to pull the pulley onto the new pump.
Would be best to find a shop to press it off and on for you if possible.
