Why Your Car Won’t Start in the Cold

Are you struggling to start your vehicle up? This is something that can happen quite often during the winter months. Needless to say, you need to figure out why your car won’t start so that you can get to the bottom of the problem. Considering that, we are going to reveal some of the different reasons why your vehicle may not start during the cold months. 


One of the reasons why vehicles may not start when the weather is cold outside is because batteries produce a lower amount of electrical current when the weather is cold. This is because of the chemical reaction, which is slower during the winter months than during the summer months. 

Put in simple terms, cold batteries are simply not going to generate the same amount of power when compared with warm batteries, and this impact can result in issues with starting your vehicle. 


Another reason why your car may not start during the winter months is that engine oil becomes thicker when the weather is cold, and so it will not flow around your engine as effectively. This means it is more challenging to pump the oil through the engine block, which will cause more strain on your battery. 

If you have a car battery that is already quite low on power, this can result in your vehicle not starting properly.


If you drive a vehicle that is older and it has a carburetor, there is a chance that you may also experience some sort of problems when it comes to starting your car during the winter months. The reason for this is because carburetors are pretty susceptible to cold conditions, especially because of the fact that the nozzles are small.  

They can then end up becoming clogged and this means that the moisture will not evaporate, resulting in the ice to build-up. A lot of contemporary vehicles do not come fitted with a carburetor, so if yours was built within the past two decades, this is something that you are most likely not going to need to worry about. 

Fuel Lines

The final reason why you may end up with a vehicle that does not start in the winter months is because there may be moisture within the fuel lines, which can then end up being frozen and this can create a fuel blockage, which means that the engine is not going to start. 

This is something that happens on quite a regular basis in the fuel lines, which are thin, and therefore, it is easy for them to end up getting blocked up by ice. Don’t forget, diesel gels in the cold, meaning powering a diesel engine takes longer.

To conclude, there are a number of different reasons why your vehicle may not start during the colder months. If you are not able to get your car back on the road, you need to get in touch with a vehicle repair company as soon as possible so that they can rectify this as soon as possible.
