Munich - The timing belt is one of the essential car parts that has to be replaced regularly and motorists are advised to strictly conform to the recommendations listed in the owners manual, according to Germany's automobile association ADAC. Most car makers list a certain amount of kilometres or the age of the vehicle when the timing belt needs replacement.

Normally the timing belt has reached the end of its tether after the car has clocked between 100,000 and 120,000 kilometres. But Maximilian Maurer, an ADAC expert, points out that even if an older car has low mileage, the timing belt could need replacement.

"A timing belt is made of rubber and rubber simply has a limited lifespan," Maurer points out, warning that it can even be dangerous to neglect a replacement.

"The timing belt can tear suddenly causing the engine to stop working immediately. That could lead to really tricky situations or even an accident," he says. Not only that.

If a timing belt breaks, it normally means that the engine needs complete replacement. The belt connects the crankshaft to the camshaft of a combustion engine which in turn regulates the opening and closing of the valves. If the system suddenly stops working, a piston can slam into an opened valve, causing much damage. (dpa)
