How To Install Buick Century Power Steering Pump

I have a 2004 Buick Century and I need to see a picture of how the power steering sits. My nephew tore apart the engine. I know how to replace it but the issue is that I don’t know what bolts go where or if the unit is set right.

Mechanic JK:
What engine size in your Buick?

I believe 3100.

OK. I am an not allowed to post diagrams, schematics etc in this free chat. Other than that, it sits on top with 3 bolts that go through the pulley. Is it set in place next to the alternator?

Ya i got the two hoses going against the block and the unit placed so that the bolts will fit in but I don’t know what size of bolt it took or anything I cant find them. I was looking for a picture or diagram to see how everything went and the size of the bolts

Well, the bolts have 13mm heads and are about 2 inches long. I don’t have thread pitch or any specifications like that.

Cool thanks. Do you know where I might be able to get a blow up diagram of the engine and its parts?

I do not really have one picture that would be very good for trying to see good locations and positioning of components. Pictures are broken down into sections and they are exploded views. Can get a little confusing to try to understand locations unless you are experienced at looking at these types of views. You may want to go to the dealer parts department. They can pull up these views and the parts guy may be able to give you a little description.

Thanks for the help.


What do I need to change the camshaft pulley? Apparently it is approx. 1/4 to 1/2 inch out of alignment with the other pulleys. It is making the belt sheer into two belts. The belt will not stay in the groove. It makes it come halfway off of the camshaft pulley.

Ok, there is no camshaft pulley on your car. I’ll have to assume you mean the belt tensioner pulley which is part of the tensioner assembly. Replacement is extremely easy as it is just one bolt that holds it on. Remove the belt, replace the tensioner, install a new belt. The other pulleys on your vehicle would be the power steering pulley, alternator pulley, water pump pulley, idler pulley, and crankshaft pulley (harmonic balancer). None of the others really ever get out of alignment unless you have a problem with the actual component.
