Pre-Winter Car Maintenance Tips

1. Battery and Electrical System

  • Check battery health: Cold temperatures reduce battery power. Have it tested (voltage and cold cranking amps).
  • Clean terminals: Remove corrosion and ensure tight connections.
  • Inspect cables: Look for cracks or fraying in battery cables.

2. Fluids


  • Engine oil: Use the recommended winter-grade oil (check your owner’s manual).
  • Coolant/antifreeze: Ensure the mixture is correct (typically 50/50). It prevents freezing and overheating.
  • Windshield washer fluid: Use winter formula with antifreeze properties.

3. Tires


  • Tread depth: Ensure at least 3 mm (4/32") tread for adequate grip; consider winter tires for better traction.
  • Tire pressure: Check regularly—cold weather causes pressure to drop. Which can cause tire light to come on. 
  • Spare tire: Ensure it’s inflated and that you have a working jack and wrench.

4. Heating and Cooling


  • Heater: Test for proper cabin heat.
  • Defroster: Make sure it clears windows quickly.
  • AC: Still useful for defogging even in winter—ensure it operates properly.

Emergency Kit


Keep these essentials in your trunk:

  • Ice scraper and snow brush
  • Jumper cables or jump starter
  • Blanket and warm clothes
  • Flashlight with batteries
  • Non-perishable snacks and water
  • First aid kit
  • Shovel and sand/kitty litter (for traction)
  • Phone charger/power bank
