Cold Weather

 

As temperatures drop and winter settles in, it’s important to remember that cold weather can take a toll on your vehicle. From battery troubles to tire pressure changes, your car faces unique challenges during the colder months. Understanding these issues can help you prepare your vehicle and avoid unexpected problems.

Here’s a breakdown of how cold weather affects your car and some practical tips to keep it running smoothly all winter long.

1. Battery Performance Declines

Cold weather is one of the most common culprits behind dead car batteries. As temperatures drop, the chemical reactions within the battery slow down, reducing its ability to generate power. At 0°C, a car battery loses about 35% of its strength, and at -18°C, it can lose up to 60%.

What You Can Do:

  • Get your battery tested before winter to ensure it’s in good condition.
  • Keep jumper cables in your vehicle for emergencies.
  • Park your car in a garage or use a battery warmer if temperatures are extremely low.

2. Tire Pressure Fluctuates

For every 10°C drop in temperature, tire pressure decreases by about 1 PSI (pounds per square inch). Underinflated tires can affect your car’s handling, fuel efficiency, and safety on icy roads.

What You Can Do:

  • Check your tire pressure regularly during the winter months.
  • Inflate your tires to the manufacturer’s recommended PSI, which can be found in your owner’s manual or on the driver’s side door jamb.
  • Consider switching to winter tires for better traction on snow and ice.

3. Thickened Fluids

Cold temperatures can cause the fluids in your car, such as oil, transmission fluid, and coolant, to thicken. Thicker fluids don’t circulate as efficiently, which can lead to increased wear and tear on your engine.

What You Can Do:

  • Use winter-grade oil recommended by your vehicle manufacturer, as it’s designed to flow better in cold weather.
  • Check and top up your antifreeze to prevent freezing and maintain proper engine temperature regulation.

4. Frozen Fuel Lines

In extremely cold weather, moisture in your fuel lines can freeze, preventing fuel from reaching the engine. This can cause your car to stall or refuse to start.

What You Can Do:

  • Keep your gas tank at least half full to reduce the chance of moisture buildup.
  • Use a fuel-line antifreeze or gas-line antifreeze product if you’re in an area with severe cold.

5. Windshield and Wiper Issues

Freezing temperatures can cause frost or ice to form on your windshield, making visibility a challenge. Wiper blades can also become brittle and less effective in clearing snow and ice.

What You Can Do:

  • Use a high-quality windshield washer fluid rated for subzero temperatures.
  • Replace old or worn wiper blades with winter wiper blades designed for snow and ice.
  • Keep an ice scraper and de-icer spray handy for frosty mornings.

6. Thicker Belts and Hoses

Rubber belts and hoses in your engine can become brittle in freezing temperatures, increasing the risk of cracks or breaks.

What You Can Do:

  • Inspect your belts and hoses regularly for signs of wear or damage.
  • Schedule a professional inspection before winter to catch potential issues early.

7. Decreased Tire Traction

Winter roads are often slippery due to snow, ice, and slush, making traction a major concern. Summer or all-season tires may not provide enough grip in these conditions.

What You Can Do:

  • Invest in winter tires, which are designed with special rubber compounds and tread patterns for enhanced traction in cold weather.
  • Drive cautiously and maintain a safe distance from other vehicles.

Cold weather can be tough on your vehicle, but with the right preparation, you can minimize its impact and stay safe on the road. Regular maintenance and attention to these common winter car issues will help ensure that your car is ready to handle whatever winter throws your way.
