Do I really need to change my timing chain? My Volvo s40 (2003) has 45,000 miles on the clock, and a friend says I need to change the timing chain at 50K or I'll have problems. the car is in great nick and well looked after, serviced regularly, so I'm interested to know if anyione else has had problems with timing chains. Its the first Volvo I've owned and Iv'e never changed a timing chain in any car I've owned before (Vectra/Vauxhall and Fords). I'm not interested in the mechanics of it - I'll leave that to the pros. Also are the timing chain and timing belt the same thing?

First of all a clarification. In the Volvo's it is a timing belt, not a chain. Secondly, I would say it is a bit early to change it now. Volvo recommends changing at 105K, which I think is too long. Most people have it changed somewhere between 75K - 90K, but no more than 90K. And yes, you do need to change it. The engines are an interference engine and if the timing belt slips/breaks, then most likely you are going to have some bent valves, which is an expensive repair.
