5. Battery Maintenance and Testing

Monthly Battery Inspection:

• Check terminals for corrosion (white, powdery buildup)
• Clean terminals with baking soda solution if needed
• Ensure battery is securely mounted
• Test voltage with multimeter (should read 12.6V when off)

Corrosion Cleaning Process:

• Disconnect negative terminal first, then positive
• Mix baking soda with water to create paste
• Scrub terminals with old toothbrush
• Rinse with clean water and dry thoroughly
• Apply petroleum jelly to prevent future corrosion
• Reconnect positive first, then negative

6. Cabin Air Filter Replacement

Location and Access:

• Usually behind glove compartment or under dashboard
• Some vehicles have filters in engine compartment

Replacement Benefits:

• Improved air quality inside vehicle
• Better HVAC system efficiency
• Reduced allergens and odors
• Enhanced defrosting performance

Frequency: Every 12,000-15,000 miles or annually

7. Windshield Wiper Blade Replacement

Signs of Replacement Need:

• Streaking or skipping across windshield
• Cracked or torn rubber blades
• Chattering noise during operation
• Poor visibility during rain

Installation Steps:

• Lift wiper arm away from windshield
• Press release tab on wiper blade
• Slide blade off wiper arm
• Align new blade and slide until it clicks
• Lower arm gently back to windshield

Frequency: Every 6-12 months depending on climate

8. Spark Plug Inspection and Replacement

When to Replace:

• Follow manufacturer intervals (typically 30,000-100,000 miles)
• Engine misfiring or rough idling
• Difficulty starting
• Reduced fuel economy

Basic Inspection:

• Remove one spark plug at a time
• Check electrode condition and gap
• Look for oil fouling or carbon buildup
• Replace if electrodes are worn or damaged

9. Belts and Hoses Visual Inspection

What to Look For:

Drive Belts:

• Cracks, fraying, or glazing
• Proper tension (should deflect 1/2 inch with moderate pressure)
• Alignment across pulleys

Hoses:

• Soft spots or bulges
• Cracks or splitting
• Loose or corroded clamps
• Coolant stains indicating leaks

Frequency: Monthly visual inspection, professional evaluation annually

10. Lights and Electrical System Check

Monthly Light Inspection:
