When should I replace timing belt

I thought I read somewhere that the timing CHAIN needed to be replaced at 115,000 miles. It is a double chain ( there are two, hence the $200 price of the kit). However, I contacted a local GOOD shop for price (too old to muck with this stuff anymore; my back and knees are SHOT and full of metal )..I was told "you don't need to change a chain; they don't break"....WTF??? I don't believe that for a minute..chains break...eventually they stretch, skip a tooth and break..or something similar. Does ANY body think that chains DO NOT break?

Please check with the dealer. I believe that motor has a chain... not a belt.

It is recommended that u replace at 60,000 miles
