Power steering pump pully replacement

I have a 91 v6 RS and while changing out a bad water pump, I had to remove power steering pully. The lip on the pully broke while removing. I cant seem to find a replacement that fits a serpentine belt that can be confirmed OEM replacement. Anyone else come across this issue? Or have a suggestion.
Thanks in advance

Re: Power steering pump pully replacement

Are you sure the power steering pump has a serpentine belt?
My 1986 V6 has a serpentine belt on the water pump but a Vee belt on the power steering.


I'm guessing you need a water pump pulley that has both the serpentine belt and Vee groove pulleys.

I did a quick online search and didn't find one of these pulleys new, so you may have to visit your local auto wrecker.

Know of that issue all too well!

Best advice is to use an impact on the puller - lessons learnt.

Ya im sure. After cleaning the build up off I found the PN# 14100597 but can only find used on ebay. I find it crazy that no one makes an aftermarket.

He has a '91, so it would definitely be a serpentine belt. I was in the local yard the other day and came across an '87 with a full serpentine 2.8L as well, and recall an '88 at that yard years ago with the same. I don't know for sure, but '86 seems to be the last year that V-Belts were used on the V6
