If your vehicle is at least 60,000 miles it is recommended you replace the timing chain. If your timing chain broke, your engine would NOT run because the timing chain is what rotates your engines camshafts to open and close the valves. Also, you would have some serious engine damage if you were driving and your engine suddenly just quit and it happened to be your timing chain. There really is no way to "check" a timing chain as it's hidden behind the belt area of the engine (if I'm not mistaken). If you're going to go through the labor of "checking" a timing chain, you might as well replace it, as the average timing chain job costs about $220, $200 of that being the labor.
I contacted the Chevy Dealer and he informed me that the Chevy astro van has a timing "chain", not a timing belt and requires no maintanence action for this item.

I have a Chevy Cavelier - year 2000. My timing belt broke at 172,000 with no warning. It was a belt though, not a timing chain.
