1. Rust Inspection (Critical)

Why it matters: Winter salt causes rust. Rust destroys your car's value and structure. Where to check:
  • Undercarriage (most critical)
  • Wheel wells
  • Door bottoms
  • Rocker panels
  • Frame rails
  • Exhaust system
  • Brake lines
  • Fuel lines
What to look for:
  • Surface rust (orange/brown color)
  • Flaking paint
  • Bubbling paint
  • Holes in metal
  • Corroded areas
How to check:
  1. Wash car thoroughly
  2. Inspect undercarriage (use jack if needed)
  3. Check all metal surfaces
  4. Look for rust spots
  5. Check for holes or weak spots
If you find rust:
  • Surface rust: Clean and treat
  • Moderate rust: Professional treatment
  • Severe rust: May need body work
  • Structural rust: Safety concern
Cost: $0 (inspection) | $100-$300 (treatment) | $500-$2,000 (repair) Prevention: Regular washing, undercoating, rust inhibitor

2. Undercarriage Wash

Why it matters: Salt and debris accumulate under car. Removing it prevents rust. What to do:
  • Wash undercarriage thoroughly
  • Remove salt and debris
  • Use pressure washer if available
  • Pay attention to hidden areas
  • Dry thoroughly
How to wash:
  1. Use car wash with undercarriage spray
  2. Or use pressure washer at home
  3. Focus on wheel wells and undercarriage
  4. Rinse thoroughly
  5. Dry with air or let air dry
Frequency: Every 1-2 weeks during winter, deep clean in spring Cost: $10-$15 per wash | $0 if you do it yourself DIY difficulty: Easy

3. Brake Inspection

Why it matters: Winter driving is hard on brakes. Salt and moisture accelerate wear. What to check:
  • Brake pad thickness
  • Brake rotor condition
  • Brake fluid level
  • Brake line condition
  • Caliper condition
Signs of problems:
  • Squealing or grinding
  • Soft brake pedal
  • Pulling to one side
  • Vibration when braking
  • Brake fluid low
How to check:
  1. Visual inspection of pads (if accessible)
  2. Check brake fluid level
  3. Test brake performance
  4. Listen for unusual noises
  5. Check for leaks
Cost: $0 (inspection) | $100-$300 (brake service) When to replace:
  • Pads: When 3mm or less
  • Rotors: If warped or scored
  • Fluid: Every 2-3 years

4. Suspension Check

Why it matters: Potholes damage suspension. Winter roads are full of potholes. What to check:
  • Shock absorbers (should not bounce)
  • Struts (should not leak)
  • Springs (should not sag)
  • Control arms (should not be loose)
  • Ball joints (should not have play)
  • Bushings (should not be cracked)
Signs of problems:
  • Bouncing after bumps
  • Leaking fluid from shocks
  • Car sits low
  • Uneven tire wear
  • Clunking sounds
  • Poor handling
How to check:
  1. Bounce test (push down on corners)
  2. Visual inspection
  3. Check for leaks
  4. Test drive
  5. Listen for noises
Cost: $0 (inspection) | $300-$800 (suspension repair) DIY difficulty: Moderate to advanced

5. Fluid Changes

Why it matters: Fluids break down over time. Winter accelerates breakdown. Fluids to change:
  • Engine oil (every 3,000-7,500 miles)
  • Coolant (every 30,000-50,000 miles)
  • Transmission fluid (every 30,000-60,000 miles)
  • Brake fluid (every 2-3 years)
  • Power steering fluid (if needed)
  • Differential fluid (if 4WD/AWD)
How to check:
  1. Check owner's manual for intervals
  2. Check fluid condition
  3. Check fluid level
  4. Change if due or dirty
Cost:
  • Oil change: $30-$80
  • Coolant flush: $50-$150
  • Transmission: $100-$200
  • Brake fluid: $50-$100
DIY difficulty: Easy to moderate

6. Air Filter Replacement

Why it matters: Air filter gets dirty in winter. Dirty filter reduces performance and fuel economy. What to check:
  • Filter condition (should be clean)
  • Filter age (replace annually)
  • Filter type (use correct type)
How to check:
  1. Remove air filter
  2. Inspect for dirt and debris
  3. Check if light passes through

7. Tire Rotation

Why it matters: Tires wear unevenly. Rotation extends tire life. What to do:
  • Rotate tires (front to back, side to side)
  • Check tire condition
  • Check tire pressure
  • Check tread depth
Rotation pattern:
  • Front-wheel drive: Front to back, back to front (cross)
  • Rear-wheel drive: Front to back, back to front (cross)
  • All-wheel drive: Follow manufacturer pattern
How to rotate:
  1. Loosen lug nuts
  2. Jack up car
  3. Remove wheels
  4. Install in new positions
  5. Tighten lug nuts
  6. Torque to spec
Cost: $40-$80 at shop | $0 if you do it yourself DIY difficulty: Easy to moderate Frequency: Every 5,000-7,500 miles

8. Detailing

Why it matters: Winter grime damages paint. Spring detailing restores appearance. What to do:
  • Wash thoroughly
  • Clay bar treatment (removes contaminants)
  • Polish (removes scratches)
  • Wax (protects paint)
  • Interior cleaning
  • Vacuum
  • Clean windows

Total cost: $150-$450 professional | $70-$150 DIY DIY difficulty: Easy to moderate

9. Battery Check

Why it matters: Cold weather is hard on batteries. Spring is good time to check. What to check:
  • Battery voltage (should be 12.6V+)
  • Battery terminals (should be clean)
  • Battery age (replace if 4+ years)
  • Load test (battery should hold charge)
How to check:
  1. Check voltage with multimeter
  2. Get load test at auto parts store
  3. Check terminals for corrosion
  4. Clean if needed
