Over time, timing belts experience wear and degradation due to repetitive usage, exposure to high heat, and oil contamination. It is essential for vehicle owners to monitor for any signs of wear, which may include unusual sounds originating from the engine, such as grinding or whirring; visible cracks or fraying on the belt surface; or, in severe cases, complete breakage. A broken timing belt can lead to catastrophic engine failure. Knowing when to replace the belt is crucial—most manufacturers recommend replacement around every 60,000 to 100,000 miles, but this can vary significantly based on vehicle type and driving habits.
