1. Battery Load Test (Critical)

Why it matters: Weak batteries die in cold weather. Test now, replace if needed, before winter. What to check:
  • Battery voltage (should be 12.6V+)
  • Load test (battery should hold charge under load)
  • Battery terminals (should be clean)
  • Battery age (replace if 4+ years old)
How to test:
  1. Check voltage with multimeter
  2. Get load test at auto parts store (usually free)
  3. Check for corrosion on terminals
  4. Clean terminals if needed
Cost: Free test | $100-$200 for new battery When to replace: If battery is 4+ years old or fails load test. Don't wait until winter. DIY difficulty: Easy (testing) | Moderate (replacement) Why now: Cold weather reduces battery power by 50%. Weak batteries won't start in cold.

2. Heating System Test

Why it matters: You need heat in winter. Defrosting is critical for visibility. What to check:
  • Heat output (should get hot)
  • Defrost function (should clear windshield)
  • Blower motor (should work on all speeds)
  • Temperature control (should adjust)
  • Coolant level (needed for heat)
How to test:
  1. Start engine and let warm up
  2. Turn heat to maximum
  3. Test all fan speeds
  4. Test defrost function
  5. Check for unusual smells or noises
Common problems:
  • Low coolant (no heat)
  • Clogged heater core (weak heat)
  • Blower motor failure (no air)
  • Thermostat stuck (engine won't warm)
Cost: $0 (test) | $50-$200 (diagnosis) | $200-$800 (repair) DIY difficulty: Easy (testing) | Moderate to advanced (repair) Why now: Fix heating problems before you need them. Cold weather makes repairs harder.

3. Antifreeze Concentration Check

Why it matters: Coolant must protect to freezing temperatures. Check concentration now. What to check:
  • Coolant level (should be between min/max)
  • Coolant concentration (should protect to -35°F minimum)
  • Coolant condition (should be clean, not rusty)
  • Coolant type (use correct type for your vehicle)
How to check:
  1. Check coolant level in reservoir (when engine is cool)
  2. Use antifreeze tester to check concentration
  3. Look for rust or contamination
  4. Check owner's manual for correct type
Protection levels:
  • 50/50 mix: Protects to -34°F
  • 60/40 mix: Protects to -62°F
  • 70/30 mix: Protects to -84°F
Cost: $10-$20 for tester | $30-$50 for coolant flush DIY difficulty: Easy Why now: Ensure protection before first freeze. Frozen coolant can crack engine block.

4. Tire Tread Depth Check

Why it matters: Good tread is essential for winter driving. Check now, replace if needed. What to check:
  • Tread depth (should be 4/32" or more)
  • Tire condition (should not be cracked or damaged)
  • Tire pressure (should be correct)
  • Tire age (replace if 6+ years old)
How to check:
  1. Use penny test (insert penny head-first into tread)
  2. If you can see all of Lincoln's head, tread is too low
  3. Check all tires
  4. Check for uneven wear
Minimum tread:
  • Summer: 2/32" (legal minimum)
  • Winter: 4/32" (recommended)
  • Snow tires: 6/32" (recommended)
Cost: $0 (check) | $400-$800 for new tires When to replace: If tread is below 4/32" before winter Why now: Replace tires before winter weather. Don't wait until you need them.

5. Wiper Blades Replacement

Why it matters: Good wipers are essential for visibility. Winter weather is hard on wipers. What to check:
  • Blade condition (should be flexible)
  • Blade performance (should clear windshield)
  • Blade age (replace annually)
How to check:
  1. Test wipers (should clear windshield completely)
  2. Check for streaking
  3. Check for skipping
  4. Replace if needed
Cost: $20-$50 per set DIY difficulty: Very easy (5-10 minutes) When to replace: Annually, or before winter Why now: Replace before winter weather. Don't wait until you need them.

6. Washer Fluid Top-Off

Why it matters: You need washer fluid for visibility. Use winter formula. What to do:
  • Check washer fluid level
  • Fill with winter formula (won't freeze)
  • Keep reservoir full
  • Test washer function
Winter formula:
  • Protects to -20°F or lower
  • Prevents freezing
  • Cleans better in cold
Cost: $3-$5 per gallon DIY difficulty: Very easy Why now: Ensure you have winter formula before first freeze.

7. Emergency Kit Assembly

Why it matters: Winter breakdowns can be dangerous. Be prepared. Essential items:
  • Blanket or sleeping bag
  • Flashlight with extra batteries
  • Jumper cables
  • First aid kit
  • Non-perishable food
  • Water (bottles that won't freeze)
  • Ice scraper and snow brush
  • Shovel (collapsible)
  • Sand or kitty litter (for traction)
  • Warning triangles or flares
  • Phone charger (portable battery)
  • Warm clothing (gloves, hat, boots)
Cost: $50-$100 for complete kit Where to store: In trunk, easily accessible Why now: Assemble kit before winter. Don't wait until you need it.

8. Insurance Check

Why it matters: Ensure you have proper coverage for winter driving. What to check:
  • Coverage is current
  • Roadside assistance included
  • Towing coverage
  • Rental car coverage
  • Comprehensive coverage (for winter damage)
What to consider:
  • Winter driving risks
  • Increased accident risk
  • Weather-related damage
  • Towing needs
Cost: Varies by policy Why now: Review coverage before winter. Update if needed.

9. Lights Check

Why it matters: Winter days are shorter. You need all lights working. What to check:
  • Headlights (high and low beam)
  • Taillights
  • Brake lights
  • Turn signals
  • Hazard lights
  • Fog lights (if equipped)
How to check:
  1. Test all lights with engine running
  2. Have someone check brake lights
  3. Replace burned-out bulbs
  4. Clean lenses (improves visibility)
Cost: $5-$20 per bulb | $50-$150 for LED upgrade DIY difficulty: Easy Why now: Fix lights before winter. Shorter days mean more night driving.
