  1. Battery Issues:

Suffering from the problem of the car won’t start in the cold, but the battery is good? Battery issues are among the most frequent causes of a car not starting in the cold. The chemical reaction inside the battery slows down as the temperature drops. This causes the battery to lose power. In other cases, even though the battery is ultimately charged, it may not have enough power to start the car. Try turning on the headlights to see if the battery is the issue. If they are dim, it’s a sign that the battery is struggling.

How To Prevent A Flat Battery?

  • You’ll need to jump-start a flat battery – but never attempt this on a frozen battery, as they can explode. You should always wear protective gear and use jump cables.
  • Check your battery leads if your car won’t start in the cold. If you can see a thick, salt-like substance, they’ve corrupted. You can only clean these with baking soda and water once you’ve disconnected your cables.
  • Suppose your battery is over three years old. In that case, it’s worth replacing, as older batteries tend to drop their charge far quicker. In the meantime, it’s worth regularly charging your battery during colder months, mainly if it is older and you frequently make short trips.
  • Similarly, changing and checking your vehicle’s oil levels can help keep the battery optimized – you may even need to change over to a winter-appropriate oil during colder months. But always check your vehicle manufacturer’s recommended oil viscosity rating.


  1. Fuel Issues:

Another reason why a car won’t start in the cold is due to fuel problems. In cold weather, the fuel in the tank can become thick and sluggish, making it difficult for the engine to ignite. Keeping the gas tank full during the winter is essential to prevent this.

How To Prevent Issues With Car Fuel Systems?

  • Keeping the car’s fuel tank close to full can help reduce condensation risk. You can also add fuel line antifreeze to your car, which helps to prevent this from happening.
  • If you think your car’s fuel system might be having issues, you may need to clean it professionally. Warm the fuel lines by wrapping them in hot towels and placing a bowl of hot water underneath the fuel tank, which should help to un-freeze any ice particles.

  1. Starter Issues:

If the battery is charged, and the fuel system is working correctly, but the car cold won’t start, the problem may be with the starter. The starter motor can become sluggish in cold weather, making it difficult to turn over the engine.

How to prevent issues with the alternator?

  • Reducing stress on the charging system—meaning reducing the usage of electrical devices and accessories like the radio/MP3 systems and heating—can help with the alternator.
  • You can measure the voltage your generator produces with a multimeter. However, the alternator or starter motor needs to be changed if there is a problem. The procedure is relatively complicated and needs to be done by a qualified mechanic.
