Factors Affecting Crank Time in Cold Weather

Have you ever tried starting your car on a chilly morning only to hear your engine crank for longer than usual before it starts? The culprit is often cold weather, which can slow down the starting process due to a variety of factors. Let’s take a closer look at some of the most common reasons for longer crank time in cold weather.

Thickened engine oilEngine oil thickens in cold temperatures, making it harder to pump through the engine and increasing strain on the battery. This can lead to a slower crank time as the engine struggles to turn over.
Old/faulty batteryCool temperatures can cause slow car starting by affecting the strength of the current from the engine’s battery. Weak or dead batteries are a common cause of starting problems in cold weather.
Reduced fuel evaporation ratesCold temperatures can cause fuel to evaporate more slowly, reducing the amount of vapor in the fuel mixture needed for combustion. This can cause a slower crank time or even prevent the engine from starting altogether.
Fuel contaminationMoisture in fuel lines can freeze and cause blockages, while diesel can “gel” in the cold. This can result in a lack of fuel flow to the engine, leading to a slower crank time or no start at all.
Carburettor issuesOlder cars with carburettors can experience cold weather starting problems, as carburettors rely on a precise mixture of fuel and air to operate. If the fuel mixture is too rich or too lean due to cold weather, the engine may struggle to start.

It’s important to note that slow car starting can be caused by a variety of conditions, including weather, battery health, starter health, fuel pump health, and other factors. However, by understanding the specific factors that can cause longer crank time in cold weather, car owners can take steps to prevent starting problems and keep their vehicles running smoothly.

For example, frequent oil changes can help ensure that engine oil stays thin and easily flows through the engine in cold temperatures. Checking and replacing a weak or dying battery can also help prevent cold weather starting issues. In addition, using a fuel additive designed for cold weather can reduce the risk of fuel gelling and other fuel-related problems.

By taking these and other preventative measures, car owners can ensure that their vehicles start smoothly and reliably, no matter how chilly the weather may be.
