I had a 2001 Vectra B 2.2 SRI 150 and that was chain driven rather than a belt, if you hear the engine rattle stop driving it immediately and tow it to a garage as they are renowned for snapping. Mine snapped and was going to cost more than the car was worth to replace so ended up in car heaven. Hope this helps.
Its a belt but its the rollers that fail check out www.v6technicians.co.uk they know all bout this engine It has a timing belt. Only some diesels or the 2.2 petrol Vectra's have timing chains.
