Timing belt/chain

I was wondering when I should change my timing chain, if I should at all. I have 2000 altima, with 100k miles on it. Or if it has a timing belt on it, im unsure.... If this could go, what would happen if it went, I know my friend on his cavelier, bent all his valves and had to junk the car when the timing belt went. How much would a new belt cost?

Never...
The timing chain will last the life of the car's engine. Our car's don't come with timing belts. Now, there's a drive belt for the altenator, water pump, a/c and so on. If those belts fail, you'll get some warning sign, such as a squeling sound. They do need to be replaced about 100,000 miles

Yes but the chain can skip a tooth and mess something up pretty nicely.

however much DJMystery is correct he is still wrong. That is such an unlikely event. It is a possibility but its just as much fate as a tree falling on your car while driving down the road. If you chain skips a tooth you'll notice it, no doubt about it. But if it doesn't do it don't worry about it. The chain guides/covers may become a problem (by rattling and making noise) but not the chain itself so I wouldn't worry about it.

the problem wont come from the chain itself, it will come from irregular maintenance screwing up the chain tensioner. if the tensioner fails, then it can skip a tooth. by that time though, you should be hearing the chain slapping around pretty badly.
