No problem, happy to help.
Volvo changed the design of the pulleys and cambelt from a square tooth design to a round tooth design for the later cars - the round tooth cambelts have a longer service interval and are quieter in use. Obviously enough they are not interchangeable- the set of three pulleys (crank, camshaft and intermediate shaft) and the cambelt need to be either one or the other.
Your car should have a set of round tooth pulleys and belt, as they were used from around 1991/1992 onwards, but it’s easy to check- I’ve attached photos of what the two types look like - the shape of the teeth is noticeably different when viewed side to side.
Brookhouse have both types of crank pulleys in stock.
Cheers
