Why Winter Prep Matters
Cold weather exposes every weakness. A battery fine at 10°C might fail at -12°C.
1. Battery Test
Auto parts stores test free. Over 3 years old or under 80% of rated CCA? Replace.
2. Tire Check
Minimum 4/32" for all-seasons, 6/32" for snow. Use the tread wear indicator bars moulded into the tread, or a depth gauge. If tread is under 3mm, it's time to replace.
3. Wiper Fluid and Blades
Winter formula rated to -30°C. Summer fluid freezes on windshield. New blades if streaking.
4. Coolant Check
50/50 antifreeze/water mix. Most shops test free. Low antifreeze can crack your engine block.
5. Emergency Kit
Jumper cables, blanket, flashlight, ice scraper, small shovel, cat litter (traction), water, snacks.
