How often do I have to change the timing belt

If you need to ask this question, take it to a dealership for replacement belts.

Buy a chiltons book for your vehicle or a shop manual off ebay

Any auto parts store will have this part and any other engine part you need with a few exceptions. If you want to buy it a greatly reduced cost go to www.rockauto.com. You also need to replace the water pump and timing belt idler and tensioner pulley when you do the change.

It may be worth looking at the timing belt tensioner pulley bolt to see if it hasn't worked loose, the belt may be about 3/4" of slack, which could cause the belt to slap against the inside of the cover at low rpms. It can also slowly shave away the backing of the belt. There could be about half a cup of timing belt dust/shavings collected in the bottom of the lower timing belt cover.
