What to Do If Your Car Won’t Start in the Cold Weather

Winter mornings in Ohio can be very cold, snowy, and windy, and you may find that your car will not start.  When the temperature drops, there can be various reasons why your vehicle does not respond. Knowing the right thing to do in this situation is vital in order to get on the road as quickly as possible.

The auto repair experts at Overbeck Auto Services in Amelia will walk you through the most common reasons a car will not start in cold weather.

How Does Your Car Work?

When you insert the key into the ignition switch, the controller sends an electrical current through the starter relay. The starter relay is a small electromagnetic device that activates the starter motor. When the starter motor is energized, it turns the engine over, which causes the fuel and air mixture to be drawn into the cylinders. The spark plugs ignite the mixture creating a spark. This spark ignites the fuel in the cylinders which causes the engine to turn.

The engine turning creates compression, which forces the piston down on the intake cycle. This downward motion forces the exhaust valve to open, and the spent gasses are expelled from the engine. The cycle then starts over again and the engine continues to run. 

Unless all these parts come together correctly, your car will not start.

What Happens When It Is Cold Outside?

The biggest problem you face in cold weather is that the low temperature causes your car’s oil, transmission fluid, brake fluid, and other essential liquids to thicken, preventing them from flowing freely through the engine. If you have worn fuel or brake lines, the moisture outside can seep in and freeze, causing blockage and eventual breakage.

The battery is also under a lot of stress in cold weather. When the temperature falls below freezing, the battery’s output drops by as much as 50 percent making it harder to efficiently work. 

In addition, the cold can also affect the electronic systems in your car. The computer modules, sensors, and relays can all be adversely affected by the low temperatures.

When all these components fail, it can prevent your car from starting.

How to Start Your Car in Cold Weather

According to our expert auto mechanic, if you find yourself in a situation where your car will not start, there are a few things that you can do to increase your chances of getting it going,

Cycle the Key to Warm Up the Ignition

Ensure all the components that pull energy from the battery, such as the radio, heater, and interior lights are turned off. These components can draw power from the battery and prevent it  from starting the engine.

Next, put the key in the ignition and turn it to the “on” position, but do not start the car. Instead, hold it in this position for about 10 minutes. This will heat the ignition and help to get the engine going.

If this tactic isn’t successful, move on to the next one!

Try to Use a Jump Start

Your battery may need a little nudge to start the engine in cold weather. This is where a jump start comes in handy. Call a friend, a relative, or someone with a jumper cable. Park the running car next to the one that will not start and open both hoods. Connect one end of the jumper cable to the positive terminal on the good battery. Connect the other end of the jumper cable to the positive terminal on the dead battery. Do not connect the negative cables together.

Start the engine in the running car and let it run for a few minutes. Then try to start the vehicle that has had the jumper cables attached. If jumping the battery gets your car moving, allow it to run for a few minutes before disconnecting the cables and make sure to swing by the auto repair shop to have your battery checked.

There’s a good chance your battery will have future problems so getting it checked out  is a good idea.
