This is a question I get asked after we generally advise this work to be done. It won’t make the car go any better, or be more economical, in fact you probably will notice no difference at all in the way that the car performs, however the consequences of it breaking in most cases result in severe and sometimes catastrophic engine damage. The belt in question links the top and bottom of the engine, and allows the lower pulley to drive the upper pulley (camshaft) and it may well drive other components too, usually a water pump, via tensioners and guide wheels. Different manufacturers will have differing change intervals, and the belt should be replaced at or even before this is reached, along with the relevant pulleys and wheels. Some manufacturers sell it as a complete kit others not, but be warned if you decline this job it might cost you a whoever lot more to put it right,after it has failed in service, typically the cost of replacement is around 15-20% of the cost of failure rectification, so be warned your garage only want to keep the car reliable.
