When does a cambelt need changing?
Answers:
yesterday (if it snaps and trashes your engine)
Every 10,000 miles. You dont! You do it as a precaution, if not and it goes, you're engine will be Fubar'd.
get it looked at , its better to get it changed before it goes
Just follow manufacturers guidelines, they vary between 40 and 80,000
Check your hand book, it's a lot more than 10000 miles, your dealer should be able to give you an idea, also it can sound different when it's going, but be careful it can just go without warning, and then that's a big job, and lots of money.
A chain belt last longer than any other type. Each manufacturer advises dependent on mileage - anything from 60,000 miles upwards or after 4/5 years if low mileage. I always go for 10,000 LESS than recommended.

i think garages see "V" coming, every 10,000 miles is definitely not needed, every vehicle is different and vary from 50,000 to 80,000. You need to check your vehicle handbook to be sure, just don't go over it or you are looking at a major repair bill. It has no wearing noises so there is no warning it will break, good maintenance is your only hope.
Between 40 and 80 thousand miles. They have more wear and tear when used in towns than motorways.
When they snap, if you do try to restart you knacker the engine.
Your car has an owner's manual. Read it. That's what it's for. It tells you what maintenance is required. A timing belt needs to be replaced typically at the manufacturer's specified mileage of 60,000 to 100,000 miles as stated in your owner's manual. Call your dealer if there's any doubt. See the listing of car models on the Gates website to see if your engine is an interference engine that will be damaged if the belt breaks. Also it tells when to replace the belt.

You can't tell. Just follow manufacturer's guidelines which vary - between 50,000 to 80,000 I believe. Get it checked though, mine went as hadn't been advised about changing it and this cost a fortune as parts of the engine were damaged.
your vehicle has a specific maintence schedual, you shoul find out from your dealer when it is time to replace it. not doing so will cost you an expensive repair.
it really depends on the car but most cars are around 60000 miles.
Cam belt life is dependant on type of motoring, make and age.
The problem with cam belts can be caused by garages not using a tensioning tool when replacing belts - they use the thumb and forefinger method (ie guess), which I've done myself. Over or under tensioning reduces life of the belt dramatically hence some peoples over enthusiastic reccomendations.
Belts are best tensioned with either a clavis, burroughs or manufacturers device.
Asscociated components lke water pumps and idlers need careful checking too. Having worked in engine development and retail garages, the approach of some garages including big main dealers seems lacking at times.
Follow the manufacturer but if u do your own maintenance periodically check the belt visually. If it has any oil on it (from cam seals leaking etc.) fix the leak and change the belt. Oil weakens the belt. Also check tension on the belt and any visible wear on the pulleys/belt. Not a bad idea to change the belt more frequent if u want real peace of mind but only if your engine will bend valves if belt breaks. If it is an engine that does not bend valves there is no need to vary from the manufacturer.
