How many miles until drivebelt change?

[SilviaSR20DET]

I have 50000 miles on my 96 240sx base and was wondering how often do you change all the drive belts? Is there any signs of wear that you can see and what should i be looking for. Thanks

Should be replaced at 60k miles or soon before. If there worn bad they can snap or squeel. It costs about 15-20 for new belts, and about an hours time replacing the belts depending on how mechanicly inclined you are.
