The specs / part no. I have been told are 13A0890 belts for both power steering and air con, and for some RB30 fan belts while others are 13A0875. Mine is the 13A0875. I couldn't find out any way of identifying which it is without the old belt, but the 13A0890 was clearly too long when I tried fitting it to my car, it had almost no more adjustment after installation, let alone after it would have relaxed somewhat.
After changing the belts I had a horrible whine coming from the front of the motor. I repeatedly tried changing tension on the belts with no change. Changed the worn air con tensioner pulley bearing, and still no change. After isolating the noise to the fan belt, I suspected the replacement belt may be to blame so I bought another brand of belt and changed it over and... FIXED!
The other belt was the right size but still made a terrible noise. I now have Gates brand V belts on all three and it is quieter than before the belt change.
