Running around the camshaft and the crankshaft, assisted in its duties by the idler pulley, the Volkswagen timing belt/timing chain serves to keep the crankshaft, valves and piston working together in a smooth, organized fashion, ensuring that the valves operate in a timely manner to let air and fuel into the engine for the combustion process and to let exhaust out. Proper maintenance of the Volkswagen timing belt/timing chain is an absolute necessity, and it should be replaced at about 60,000 miles, although some service schedule estimations put the number as high as 90,000. For safety's sake, the lower number is the better option, as with some engines - interference engines, in particular - serious and expensive mechanical damage can result from a timing belt/timing chain snapping or breaking. In other types of engines, the braking of a Volkswagen timing belt/timing chain is much less dramatic, requiring merely a replacement to return to normal function. It should be noted that often snapping or breaking can happen without warning, so when the recommended number of miles at which it is recommended that your VW timing belt/timing chain be replaced rolls around, even if it is not showing visible damage, it is still a good idea to just go ahead and take care of it.
