In cold weather, engine oil thickens and doesn’t flow as well. Moisture in the fuel lines can also freeze and cause a blockage, causing the engine to not start, Buskohl said. “To start a car in freezing cold winter weather, start by shutting off any accessories, like the heater, radio and lights,” she said.
Why does my car hesitate to start when it’s cold?
Below freezing temperatures can cause a chemical reaction in your vehicle’s battery which will lead to produce less electrical current. Cold batteries simply don’t produce the same amount of power as warm batteries, and this is one of the most common reasons why your car won’t start.
Why does my car hesitate when starting up?
A lag between when the ignition key is turned to “Start” and when the starter kicks the engine over could be caused by a corroded or poorly connected high current connection to the starter – say a battery cable connection.
How often should I start my car and let it idle in cold weather?

How do I protect my car battery in cold weather?
You can provide your battery with protection from the cold by parking in a garage or underneath a covered area. This will keep snow or ice from landing and freezing on your vehicle. Garages, while often not heavily insulated, can also provide a warmer space for your car.
Does idling a car charge the battery?
Assuming the alternator, engine, belt, and battery are all in working order, then yes, a car battery will charge when idling. The only caveat is that it doesn’t really “charge” that fast. The belt will spin slower, rotating the shaft slower, and producing less electricity to recharge your battery.
Can cold weather affect starter?
Cold weather usually thickens the engine oil. Therefore, the starters require more power to start the engine. This brings in more load onto the battery affecting it severely. Ultimately, the starter gets less energy to start the engine.
Is it good to floor your car once in awhile?

How far do you need to drive to charge a car battery?
“It needs to be driven and not idled.” That means driving at least 10 km at a time, and longer in the winter, because you’re using the heater, rear defroster and heated seats – they draw a lot of power, which means less power will be available to recharge the battery, Feist says.
What is a cold start up?
When your car’s engine is colder than its normal operating temperature and you start it, that’s a cold start. That means that every time you start your car after it sits for a long period of time, you are having a significant impact on the air quality.
Does cold weather affect car alternator?
But there’s one more component to keep an especially sharp eye on during winter: your alternator. With that extra strain, sometimes it takes the alternator longer to recharge the battery. That, in turn, may leave the battery a little less power to start the engine when it’s cold.
