ALTERNATOR/ FAN belt snapped, length help ASAP

[ukvolvo]

Well my lovely lady returned from night shift today and the fan belt has completely disintegrated. No part numbers left etc.

The local car stores think the car is a twin ribbed belt which it is not.

Its a 93 onwards d24tic with air con (940)

I have measured the distance needed and at minimum size the belt seems to be 80cm roughly.

Does this seem right as i have had to just order a 800mm v belt and hope its right? I was meant to start a new job today and had to phone in...Isnt life great at times

Thanks
Mick
