Many car owners know that extreme weather can be damaging to their cars. But they still don't take any of the extra steps in order to protect their beloved vehicles! If you wait too long to prepare your car for the winter months, you might even find yourself having to deal with a car that won't start. For some, the car won't start in the morning before work. For others, it could happen in the middle of the day. A car that won't start can be a huge hassle, no matter what time of day it is.

Reasons Why Your Car Won't Start In The Cold Weather

  1. Your Battery Is Producing Less Power
    Due to the drop in temperature, car batteries typically produce less power. This occurs because the chemical reaction that is required to start your car will be slower. This can eventually cause your car to fail to start if the weather is cold.
  2. The Oil In Your Vehicle Is Too Thick
    In cold weather, your car's oil will become much thicker and it won't move through the system like it is supposed to. With the engine struggling to pump the oil throughout the system, this will put additional strain on your car's battery. If you battery is too strained, your car may not start.
  3. There Could Be Water In Your Fuel Lines
    This is typically less common of an issue, but there might be water droplets or moisture in your fuel lines. If this happens, cold weather can freeze the moisture or water droplets, causing a blockage of ice. If your fuel lines are blocked by ice, then your car won't start.
  4. The Carburetor Isn't Working Properly
    For older vehicles that have a carburetor, the carburetor could also become clogged due to a buildup of ice. The small nozzles make it fairly easy for ice to build up, causing this issue of a car that won't start even more likely to occur. With that said, many modern cars don't have a carburetor, so you only need to worry about this if your vehicle is an older model, such as classic cars.

How To Get Your Car Running Again

If you are on a time crunch and need to get on the road fast, jumpstarting your car might do the trick! To jumpstart your car, you will need a car with a properly working battery and jumper cables, which we recommend keeping in your car at all times in case of an emergency. If you have both of those things, give it a try! If your car won't start, even after attempting to jumpstart it, you might need to see a professional.
