How often should the engine timing belt be replaced?

[DiCharlotte]

Engine timing belts should be replaced every 50,000 to 60,000 kilometers. When replacing the timing belt, proper timing alignment must be ensured, and genuine parts should be purchased. The timing belt in a car helps reduce engine noise during operation. Most vehicles use a double overhead camshaft (DOHC) design, which features two camshafts - one controlling the intake valves and the other controlling the exhaust valves. The timing belt is responsible for driving these camshafts. The engine timing should never be arbitrarily altered, as incorrect timing can lead to reduced engine power and even valve collision, requiring engine disassembly for repairs. Regular replacement of the timing belt is essential, as prolonged use may cause belt breakage during operation, which is potentially dangerous and could result in engine damage.
