How many kilometers can a car drive if the belt is broken?

Cannot continue driving. The alternator belt is the drive belt for the engine's external accessories, which typically powers the alternator, air conditioning compressor, power steering pump, water pump, etc. If the alternator belt breaks, the consequences are severe, not only affecting driving safety but also potentially causing the vehicle to break down. Here is relevant information: Function of the belt: The car belt serves as a link between the upper and lower parts, connecting the timing wheel on the engine cylinder head at the top and the crankshaft timing wheel at the bottom. Car belt: After starting the engine, the car relies on the belt to continuously rotate the alternator. The belt needs to be replaced; otherwise, it may break. During each maintenance service, it is recommended that the owner check the belt. If the belt shows signs of slipping or severe cracks, it should be replaced immediately.
I once experienced a belt snapping while driving. Honestly, if it's just the belt driving the alternator that breaks, the car can still rely on the battery for a while. Theoretically, you could drive 20-30 kilometers, but it's really gambling with luck. I tried it once and only made it 3 kilometers before the engine started smoking with terrifying temperature spikes, ending up with a 6,000-7,000 yuan repair bill. In hindsight, pushing through was foolish - water pump failure causing engine seizure is way too common. So my takeaway is: if a belt snaps, immediately pull over, turn on hazard lights, and call a tow truck. Don't penny-pinch here. During regular maintenance, always check belt condition - replace at the first sign of cracks for peace of mind and safety. Neglecting this small detail can lead to huge troubles on the road.
As a seasoned driver with 30 years of experience, I know exactly how far you can go when a belt breaks. If it's the belt driving the alternator and air conditioning, the battery might last you about 10 kilometers at most, but on the highway, the risks are too high—the engine can easily overheat and get damaged. I've seen many rookies push their luck and end up stranded in less than 5 kilometers, facing repair bills in the tens of thousands. My advice: don't take the risk. If you hear unusual noises, pull over immediately—safety comes first. During routine maintenance, always check the belt for wear and tension, and replace it regularly to stay trouble-free. If you encounter an unexpected issue on the road, stay calm, pull over safely, and seek help—that's your best bet.
