What to Do When the Car Won't Start in Cold Weather?

There are several solutions to address the issue of a car not starting in cold weather: 1. Promptly and effectively recharge the battery. The typical lifespan of a car battery ranges from one and a half to three years, and it should be replaced if it exceeds this period. 2. Replace the engine oil with a more suitable viscosity for cold weather, as oil tends to thicken in winter, making it harder to flow. 3. Replace the spark plugs in a timely manner. 4. Regularly clean the electronic throttle to prevent unstable idling and increased fuel consumption caused by carbon buildup on the throttle. 5. Add antifreeze to prevent the engine from cracking due to freezing, which can lead to the water pump failing and the car not starting. 6. In winter, try to park the car indoors or in an underground parking lot to avoid engine damage caused by low temperatures.
I think I've encountered this situation many times. When a cold car won't start, the first thing to check is the battery. Cold weather accelerates battery aging, and when the voltage drops below 10V, it simply can't power the starter. If turning the key gives no response and the lights don't come on, there's a 90% chance the battery is dead. Another possibility is that the starter gear is stuck or worn out, making it hard to turn in low temperatures. Sometimes fuel system issues can also cause trouble, like a clogged fuel pump filter or degraded fuel leading to incorrect air-fuel mixture. For safety, avoid repeatedly attempting to start the car to prevent part damage; try jump-starting it with another vehicle instead. If the car stalls while driving, immediately turn on the hazard lights and pull over. For prevention, pay attention to battery lifespan—generally, it should be replaced every three years. Performing maintenance before winter can save a lot of trouble.
Last time this happened to me, I was quite anxious. My car wouldn't start in cold weather, and I thought it was a minor issue, but ended up waiting for roadside assistance for a long time. The possible reasons could be rapid battery drain or a dirty throttle affecting startup. Also, if the car sits idle for too long, the fuel quality in the tank may deteriorate, making this more likely to happen. Check if the dashboard shows any abnormal voltage warnings; if it does, inspect the battery terminals for corrosion or looseness. If there's no warning, sometimes pressing the accelerator while starting can help. If that doesn't work, call a repair shop without delay. To reduce the chances of this happening, make it a habit to turn off headlights and heaters when parking, and regularly clean the throttle and replace spark plugs. Safety first—don't take risks by trying to fix it on the road.
