I was wondering if I could use an h23 crank pulley on an H22a1?

 

You can use it. Only the section where the Alternator/AC belt goes will have less grooves on the pulley. I cant remember if the H22 pulley has 5 or 6 grooves in it. Also,for any other question you may have try the search feature. It saves time. Good luck.

 

H22 is 6 grooves and H23 is 5, I got an aftermarket crank pulley for my H22 that only had 5 grooves (like the stock H23 pulley) so i had to use the pulley off of my H23 alternator to make it work.

 

THanks...i tried that already, that's y im posting it up to save time. thanks again
