How often should the belt next to the car engine be replaced?

Car engine belts should be replaced approximately every 60,000 to 80,000 kilometers. The replacement cycle for engine belts varies among different vehicle models. Once exceeding 50,000 kilometers, regular inspections are recommended to promptly detect any abnormalities in the timing belt, primarily by listening for unusual sounds. Signs of wear or abnormalities often manifest as abnormal noises or unusual odors caused by wear. The timing belt is a crucial component of the engine and plays a key role in its normal operation. It is an essential part of the engine's valve system, connecting the crankshaft and camshaft to ensure the accurate timing of intake and exhaust through a specific transmission ratio. If the timing belt fails, the valves and ignition system will cease to function, and in severe cases, the cylinder head may also be damaged.
As a veteran driver with decades of experience, I know that engine belts require special attention. Generally, they should be replaced every 60,000 kilometers or every five to six years, depending on the vehicle model and usage conditions. My old car had a belt that wasn't replaced in time, and when it aged, it started squeaking on the overpass, nearly causing a breakdown. It also cost me an extra 2,000 yuan to repair the air conditioning system. The belt powers the alternator, water pump, and power steering. If it snaps, the entire car becomes immobilized, especially risky during long highway drives. I recommend having the mechanic check the belt for cracks or looseness during every maintenance service—it's a habit that can save a lot of hassle. In high-temperature environments or on rough roads, wear accelerates, so don't wait until the manual's limit—replace it early to avoid trouble.
In my experience with cars, I've learned that engine belts really can't be neglected. They typically last between 50,000 to 80,000 miles, but it depends on the car brand and driving habits. I ignored it once before, and the belt suddenly snapped, causing the engine to overheat. The repair cost me a full $3,000, plus additional towing expenses. The belt controls the air conditioning and charging systems, and when it develops too many cracks, it becomes dangerous. I recommend checking the belt surface yourself after each car wash for small scratches or signs of stretching. Also, pay attention to unusual noises while driving, like squeaking sounds, as these are warning signs. If you don't replace it, it could damage other components, and the repair costs would far exceed the cost of preventive maintenance. Following the maintenance schedule saves money and gives peace of mind.
