[Vwdiesel] power steering belt

[Doug & Pam]

What is the correct pulley size and belt size for the Caddy with power
steering. Mine is an 81’ and the pulley is 3 7/8” diameter. I replaced the
belt because the one in place was missing a few teeth. The new belt is 760
mm (29 7/8”) long and squeals because I can’t get it tight because all the
adjustment is used up. I tried a slightly smaller belt 750 mm (29 5/8”) long
and after a struggle got it on but the PS pulley and the WP pulley are
touching. I adjusted the belt to banjo string tight but the two pulleys were
still in contact. Can I buy an in-between belt, 755 mm (29 ¾”) long or a
slightly smaller diameter PS pulley?
