Waterpump belt length on S1?

[ElEsprito]

Hi all, I bought a new waterpump (only) v-belt but it's too short. Does anyone know the length of the correct v-belt?

MTIA!

Hi, I measured the required length by cutting to length an old (longer) belt: 638 mm outer length. Can anyone confirm pls?

Well then, I guess I posted a difficult question. I ended up ordering the belt from my local Lotus shop. It's 63cm. I'm surprised that it's not a tight fit. I can move the middle of the belt by about 15mm up/downwards. Is this normal? It doesn't seem to slip though (when turning by hand).
