What to Do If the Car Stalls in the Rain?

If the car stalls on a rainy day, do not attempt to restart it immediately. Instead, take measures to tow the vehicle to a safe location with less water as soon as possible. Reasons for stalling in the rain: 1. Water in the distributor: Once water enters the distributor, it cannot generate high-voltage sparks, causing the vehicle to stall. 2. Water in the intake manifold: Rainwater enters the cylinders with the engine's suction, leading to stalling. 3. Water in the exhaust pipe: If the water accumulation is severe and the exhaust pipe is submerged, the exhaust pressure may not overcome the water pressure, preventing gas from escaping and causing the engine to stall.

I remember that summer when it was pouring rain, my car suddenly stalled while driving through a flooded section. Experience told me not to attempt a second start, as it was likely due to water entering the engine. I immediately turned on the hazard lights, shifted to neutral, pushed the car to a safe spot by the roadside, and then contacted the insurance company to arrange for a tow truck. At the repair shop, it was confirmed that water had been sucked into the intake. They had to remove the spark plugs, drain the water, and change the engine oil to fix the issue. Now, every time I see standing water, I’m extra cautious—either detouring or slowing down to pass through steadily. Remember, if the water level exceeds the exhaust pipe, don’t take the risk. It’s also important to keep emergency numbers handy in the car. Breaking down in such weather is no time to panic.

As someone who deals with cars, if your engine stalls in the rain, there's a 90% chance water has entered the engine. Restarting it immediately will cause the piston to compress the water, bending the connecting rod instantly. The correct procedure is simple: turn off the ignition, remove the key, get out of the car, and move to a safe place. If it's raining heavily, use an umbrella and stand on higher ground. Then call for roadside assistance, clearly stating your location and the water accumulation situation—don't attempt repairs yourself. Once towed to the repair shop, check if the air filter is soaked; if it is, water has definitely entered the engine. Remove the spark plugs to drain the water and perform a cylinder compression test to check for scoring. Also, inspect all wiring connectors in the car, as short circuits are common in rainy conditions. Regularly maintain your air filter and avoid using it beyond its service life. When driving through water, maintain a steady throttle and a constant speed for safety.

Last time my friend panicked when this happened and restarted the car too quickly, which directly caused engine seizure, costing over 4,000 yuan in repairs. Actually, when the engine stalls in rainy weather, the first thing to do is to turn off all electrical appliances, especially the air conditioning, and then quickly leave the deep water area. Judge the situation by the water level outside the window—if it reaches the midline of the wheel hub, don't move the car anymore. When calling 122 to report and request rescue, clearly state the specific location. While waiting, open the hood to take photos for evidence. During repairs, pay special attention to checking the catalytic converter and oxygen sensor, as these are prone to water damage. For regular maintenance, check if the chassis sealant has fallen off. Before heading out in rainy weather, check the forecast to avoid driving during heavy rain—it's the most hassle-free approach.
