How Many Kilometers Should You Replace the Belt?
2 Answers
A car typically has two belts: the timing belt and the accessory belt. The replacement interval for the timing belt is almost the same for all vehicles, generally around three years or 60,000 kilometers. When replacing the belt, the tensioner pulley and idler pulley should also be replaced simultaneously, as their lifespan is similar to that of the belt. Even if the tensioner pulley still functions at the moment, its remaining lifespan is uncertain. Here’s additional information: The replacement interval for the accessory belt varies significantly among different vehicle brands, ranging from 3-6 years or 60,000-100,000 kilometers. The exact replacement time should be checked in your vehicle’s maintenance manual. During replacement, the tensioner pulley and idler pulley should also be replaced, as their lifespan is comparable to the belt. If the tensioner or idler pulley fails, it may lead to belt damage or even breakage.
I remember when I was young and driving, I didn't understand belt maintenance back then. As a result, the timing belt snapped on the highway, causing the engine to fail completely, and the repair cost me over ten thousand. Later, I learned my lesson – generally, timing belts should be replaced every 60,000 to 100,000 kilometers, depending on the car model and driving habits. My experience is that older cars should be replaced earlier, while newer cars can wait a bit longer, but don't exceed 100,000 kilometers. Regularly check the belt's condition – if it feels cracked or stiff, or if you hear squeaking during startup, address it immediately. During routine maintenance, remind the technician to inspect belt wear. Spending a few hundred extra can save major trouble and extend the engine's lifespan.
