Hi. Hope you can help me out, I'm looking at a 1987 cargo van the current owner removed the power steering pump when a friend told him he didn't need it, the van is listed with that note and also the A/C doesn't work. I stopped to look the van over it has a bit of rust and the windshield needs to be replaced which is no big deal, but I noticed there is a belt missing where the PS pump was located does this belt also run the A/C, if so will I have to replace the PS pump, can I just get a smaller size belt to test it out or will I have to mount an idler pulley to test out the A/C. Also the engine sounds really good it has 170,000 on it just broken in. Thanks for any insight you may have.
