how often does the timing chain needs replacing on 2007 Chevrolet Cobalt

have 61000 miles on my 2007 chevy colbalt need to know how often does the timing chain needs changing.

Asked by for the 2007 Chevrolet Cobalt
A Timing Chain will only need replacement if the chain or one of the accompanying parts wears out. I don't know the history of timing chain failure on this vehicle, but it normally doesn't occur below 150,000 miles on vehicles that are properly maintained.
Not true I have an 06 ss colbalt with 50000 and the top chain is really loose will be taking it apart this week end to see why
