Hi, we are the proud new owners of a 2000 Volvo v70. It's done 120 000ks and as far as I can see from the service manuals hasn't had the timing belt replaced. The dealer we bought it from said you don't need to replace timing belts on volvos till 200 000ks but I thought it was standard to replace them on all cars every 100 000 ks. Is that right? Should we just get it done anyway? Thanks
