Serched no luck, What is the Alt. bolt size
 

I am changing out the alternator pulley, before I go buy the socket I need to know the size. I know its bigger than 21mm

Thanks for the help

Also, a screwdriver in the top hole to lock the alternator from turning works fine. No damage will occur.

Well the post says, he thinks it's a 24mm can anyone confirm?

Thanks

It's 24mm.

Thanks
