No, you should not drive the car if the serpentine belt breaks. Continuing to drive, even for a short distance, can lead to immediate and severe damage to your engine. The most critical risk is the engine overheating, as the belt drives the water pump. Without coolant circulation, the engine can overheat to dangerous levels in minutes, potentially causing a catastrophic failure like a warped cylinder head.
The serpentine belt is a single, continuous belt that powers multiple essential components. When it snaps, you lose:
Your immediate action should be to safely pull over to the side of the road as soon as you notice the warning signs, which often include a sudden loss of power steering, a battery warning light on the dashboard, and steam or smoke from the engine bay indicating overheating. The only safe step is to turn off the engine and call for a tow truck to avoid repair costs that can run into the thousands of dollars for a new engine.

Pull over and shut it off, right now. That belt runs everything. I learned the hard way years ago. I thought I could just make it home, but the temperature gauge shot up before I got two blocks. Ended up needing a whole new engine. It's not worth the gamble. Just call for a tow.

From a mechanical standpoint, the vehicle is not operational. The serpentine belt is a critical drive component for auxiliary systems. Its failure means the water pump ceases to function, leading to rapid overheating. The alternator also stops generating electricity, so you are running solely on power, which will be depleted quickly. The safest protocol is to cease operation immediately to prevent irreversible engine damage.

I get that panic feeling when something goes wrong with your car, but you have to fight the urge to just keep going. Think of it this way: driving without that belt is like trying to run a marathon while holding your breath. The engine can't cool itself, so it's basically suffocating. Your main job is to get yourself and your car to safety, which means a slow, careful stop on the shoulder and then calling for help.

Check your dashboard lights. If the or temperature warning light comes on and the steering gets heavy, that's your belt. Don't panic. Signal, slow down, and focus on getting completely off the road. Turn off the engine to stop it from frying itself. Then you can figure out the next steps, like calling roadside assistance. The goal is to prevent a couple hundred dollars in belt and tow costs from turning into a multi-thousand-dollar engine replacement.
