Unless you have gears directly driving your camshaft, as part of an internal combustion engine you will have either a timing belt or timing chain performing that task. The belt or chain synchronizes the crankshaft’s rotation with the engine valves, allowing them to open and close at the correct times during the air intake and exhaust stroke.
Before moving on, we should tell you that while the predominant part used is a timing belt, your car engine could instead use a timing chain.
A timing belt is usually a toothed belt, and a timing chain is a roller chain. A timing belt has in recent history been the more commonly used part, but car makers are using a timing chain more often these days, as they find them to be more durable than belts.
When an automotive timing belt is replaced, care must be taken to ensure that the valve and piston movements are correctly synchronized. Failure to synchronize correctly can lead to problems with valve timing, and this in turn, in extremes, can cause collision between valves and pistons in interference engines. This is not a problem unique to timing belts since the same issue exists with all other cam/crank timing methods such as gears or chains.
The owner's manual maintenance schedule is the source of timing belt replacement intervals, typically every 30,000 to 50,000 miles (50,000 to 80,000 km). It is common to replace the timing belt tensioner at the same time as the belt is replaced.
