How Often Should a Car's Timing Belt Be Replaced?
2 Answers
Car timing belts should be replaced approximately every 60,000 to 80,000 kilometers. Other situations that require replacement include: 1. The car lacks power and cannot accelerate when going uphill; 2. The engine shakes severely at idle; 3. The exhaust pipe makes a popping sound when accelerating; 4. There is a knocking sound inside the engine when starting the motor; 5. The timing belt shows cracks or wear. The car timing belt is a critical component of the engine's valve system. As a rubber part, its function is to ensure the accuracy of intake and exhaust timing, synchronize the engine's ignition with cylinder movement, and guarantee smooth power output from the engine.
As a guy who frequently works on cars, I remember that timing belt replacement is not as simple as an oil change. Most car manufacturers recommend replacing it every 60,000 to 100,000 kilometers or every 5 to 10 years, depending on the vehicle's manual. Ignoring it can have serious consequences, such as belt breakage at high speeds, causing pistons and valves to collide and resulting in internal engine damage, with repair costs often running into tens of thousands. From the cars I've worked on, I've noticed that those used for city commuting experience less wear and might delay replacement a bit. However, if you often drive long distances or operate in high-temperature environments, the belt ages faster and needs earlier inspection. During each maintenance session, have the mechanic check for cracks or looseness in the belt—prevention is always better than dealing with a breakdown, safety first. Some older cars require replacing the water pump and other accessories along with the belt, trying to save money might end up costing more.
