    Default Power Steering Pulley

    ISO early 6.5 serp power steering pulley. I believe it is the same for late model 88-up 6.2s with serpentine drive. Thank you for your time!

    I don't recommend used PS pump pulleys, unless you know for sure how many times it's been R/R'd, and then only from/onto an OEM pump. On the upside, most parts stores have or can get an aftermarket replacement for not much. Be sure to count the grooves and measure the diameter. Most are the same, but there are some odd ducks.

    Thank you for the info! I would actually prefer a new pulley, but the GM part number 15589752 has been long discontinued and I can't find any NOS on ebay... It seems like the pulley off a small or big block of the same vintage would work but it's a different part number and none of the aftermarket suppliers I've found say they will fit a 6.5. Might have to bring the old bent pulley in to a parts store and take some measurements.

    Rock Auto lists several in stock, all under 20 bucks. Autozone lists a Dorman for $22, and they're in stock local to me.

    Thanks for the leads, I have my eyes set on Dorman 300-200. This one seems to be the closest in size, I believe the offset is different though. From what I've read I can just press it on until it's aligned with the other pulleys. Going to try it out tonight...

    Yes. As long as the pulley gets full shaft engagement, it can be moved in/out for alignment.

    I didn't note the part numbers, so I'm not familiar with that Dorman. The places I checked showed OEM replacements, and NAPA states guaranteed OEM fit and function.

    Thanks for the advice, I ended up using the Dorman pulley. It was the exact same dimensions just different offset as I suspected. Just pressed it on until it was aligned with the other pulleys. I'm not sure if there's a way to end this thread, but I got what I needed!
