What size fan belt do I need

What size fan belt do I need?

I've fitted one but even at its tightest I think it could be a too loose.

So what size should I have on my engine. 900 I think is for a 1200, 905mm? Or do I need a 912mm? I am assuming I have a 912mm?

Thanks,

J.

It's going to sound stupid, but if it's still loose and you've a standard pulley, your spacers are directly after the nut?,
A couple down the road with a late bay had the same problem, in the end his belt looked fine, I held it up to a new one and it still looked fine, I put the new one on and it was fixed, so the old one must of been stretched.
Chuck on a new one and don't forget to order two, I always keep a spare behind my drivers seat. :roll:

Had the same problem with this on mine with a non og alternator stand,ended up using a 888 fan belt so i could get some adjustment.
