22re Idler Pulley Difference

[96pearlrunner]

I'm trying to swap out my idler pulleys on my 94 22re but i want to know if there is a difference between power steering idler pulley and a/c idler pulley. Autozone carries one idler pulley, Napa carries one idler pulley, and Oreilly's carry just one idler pulley. I noticed one was bigger than the other one on mines and they're original idler pulleys. Can aftermarket idler pulleys be used for p/s and a/c?

Size is key. They are a certain size and rotate at a specific speed determined by size. If your going to fast you will over pressurize your systems and damage it. If it's too slow you won't get the required pressure to operate those properly.
Use the correct size always. No excuse no other option.

I got it figured out. the powersteering tensioner pulleys uses a replaceable bearing(Napa Part Number: 62042RSJ) and the a/c idler pulley is the one autoparts store carry.

BV, he's talking about an idler pulley. The only difference size on an idler pulley makes is on what length belt to use.

Oh then yeah doesn't matter, I guess I read that wrong.
