As the temperature drops and snowflakes begin to fall, it’s crucial to prepare your Ford Explorer for the challenges of winter driving. This comprehensive guide will walk you through essential maintenance steps to keep your SUV running smoothly and safely throughout the cold season. From tire care to battery checks, we’ll cover everything you need to know to winterize your Ford Explorer.

Tire Maintenance: Your First Line of Defense

Switch to Winter Tires

One of the most critical steps in preparing your Ford Explorer for winter is switching to winter tires. These specialized tires provide superior traction in snow, ice, and cold temperatures.

• Tread Design: Winter tires have deeper treads and unique patterns that channel snow and slush away from the tire’s surface.
• Rubber Compound: They’re made with a softer rubber compound that remains flexible in cold temperatures, ensuring better grip.
• Performance: Winter tires can improve braking distance by up to 25% compared to all-season tires in snowy conditions.

Check Tire Pressure Regularly

Cold weather causes tire pressure to drop. For every 10°F decrease in temperature, tire pressure decreases by about 1 PSI.

• Proper Inflation: Check your tire pressure at least once a month and before long trips.
• Recommended Pressure: Refer to your Ford Explorer manual or the sticker inside the driver’s side door jamb for the correct tire pressure.
• Benefits: Properly inflated tires improve fuel efficiency, handling, and tire life.

Rotate Your Tires

Regular tire rotation ensures even wear, especially during winter when traction is crucial.

• Rotation Schedule: Rotate your tires every 8,000 to 12,000 kilometers or as your manual recommends.
• Rotation Pattern: Follow the appropriate rotation pattern for your drivetrain (FWD, RWD, or AWD).

Battery Care: Ensuring Reliable Starts

Cold weather can be tough on your Ford Explorer battery. A weak battery in warm weather may completely fail when temperatures plummet.

Battery Inspection

• Visual Check: Look for signs of corrosion on the terminals and cables.
• Clean Connections: If you see corrosion, clean it with a wire brush and a mixture of baking soda and water.
• Secure Mounting: Ensure the battery is securely mounted to prevent vibration damage.

Battery Testing

• Voltage Test: A fully charged battery should measure about 12.6 volts when the engine is off.
• Load Test: This test checks the battery’s ability to hold a charge under load.
• Professional Check: Many auto parts stores offer free battery testing services.

Consider Replacement

• Age Matters: If your battery is over three years old, consider replacing it before winter.
• Cold Cranking Amps (CCA): Ensure any replacement battery meets or exceeds your Explorer CCA requirements.

Fluid Checks and Changes

Proper fluid maintenance is crucial for your Ford Explorer winter performance.

Engine Oil

• Viscosity: Consider switching to a lower viscosity oil for winter (e.g., 5W-30 instead of 10W-30).
• Oil Change: If you’re due for an oil change, do it before winter.

Antifreeze/Coolant

• 50/50 Mix: Ensure your coolant is a 50/50 mix of antifreeze and water for optimal freeze protection.
• Flush and Fill: If it’s been over two years, consider a coolant flush and fill.

Windshield Washer Fluid

• Winter Formula: Use a winter-specific washer fluid that won’t freeze in low temperatures.
• Full Reservoir: Keep the reservoir full, as you’ll likely use more in winter conditions.

Brake Fluid

• Level Check: Ensure the brake fluid reservoir is full.
• Quality Check: If the fluid is dark or cloudy, it may be time for a brake fluid flush.

Visibility Enhancements

Clear visibility is paramount for safe winter driving in your Ford Explorer.

Wiper Blades

• Winter Blades: Consider switching to winter wiper blades, which prevent ice and snow buildup.
• Replacement: If your current blades are more than six months old or showing signs of wear, replace them.

Headlights and Taillights

• Clarity Check: Ensure all lights are working and the lenses are clear.
• Restoration: If headlight lenses are foggy, use a headlight restoration kit to improve visibility.

Defrosting System

• Test Run: Before winter hits, test your defrosting and defogging systems to ensure they work properly.
• A/C Check: Remember, your air conditioning system helps dehumidify the air, aiding in defrosting.

Undercarriage and Exterior Protection

Protecting your Ford Explorer body from winter’s harsh elements is crucial for long-term durability.

Undercoating

• Rust Prevention: Consider applying an undercoating to protect against road salt and moisture.
• Professional Application: For best results, have this done by a professional.

Waxing

• Paint Protection: A good coat of wax before winter can help protect your paint from salt and grime.
• Frequency: Wax your vehicle every three months for optimal protection.

Door Seals

• Lubrication: Apply a silicone-based lubricant to door seals to prevent freezing and sticking.

Emergency Kit Preparation

Keep a well-stocked kit in your Ford Explorer for winter emergencies.

Essential Items:

• Jumper cables
• Flashlight with extra batteries
• First-aid kit
• Blanket or sleeping bag
• Snacks and water
• Ice scraper and snow brush
• Small shovel
• Bag of sand or kitty litter (for traction)
• Extra warm clothing and boots
• Phone charger

HVAC System Check

Ensure your Ford Explorer heating system is in top shape for winter comfort and safety.

Heater Check

• Performance Test: Run the heater on full blast to check for proper function.
• Odd Smells: If you notice any unusual odours, have the system checked for mold or mildew.

Cabin Air Filter

• Replacement: If it’s been more than a year or 15,000 miles, replace the cabin air filter.
• Benefits: A clean filter improves air quality and helps the HVAC system work more efficiently.

Fuel System Care

Keep your Ford Explorer fuel system in good condition for reliable winter performance.

Fuel Filter

• Inspection: Have your fuel filter checked and replaced if necessary.
• Frequency: Typically, fuel filters should be replaced every 32,000 to 64,000 kilometers.

Fuel Additives

• Gas Line Antifreeze: Consider using a gas line antifreeze product to prevent moisture in your fuel line from freezing.
• Fuel Stabilizer: If you plan to store your Explorer for extended periods, use a fuel stabilizer to prevent fuel degradation.

Brake System Inspection

Reliable brakes are crucial for winter driving safety in your Ford Explorer.

Brake Pad Check

• Thickness: Have your brake pads inspected for thickness. Replace them if they’re less than 1/4 inch thick.
• Even Wear: Ensure pads are wearing evenly on both sides.

Brake Fluid

• Level Check: Ensure the brake fluid reservoir is full.
• Quality Check: If the fluid is dark or cloudy, it may be time for a brake fluid flush.

Rotors and Calipers

• Visual Inspection: Look for signs of scoring on the rotors or sticking callipers.
• Professional Check: If you notice any issues, have a professional inspect your brake system.

Final Checks and Considerations

Four-Wheel Drive System

If your Ford Explorer has four-wheel drive:

• Engage the System: Before winter, engage the 4WD system to ensure it’s working properly.
• Fluid Check: Have the transfer case and differential fluids checked and changed if necessary.

Exhaust System

• Inspection: Check your exhaust system for leaks, which can be especially dangerous in winter when windows are often closed.
• Muffler and Pipes: Ensure all components are secure and free from rust or damage.

Scheduled Maintenance

• Service Intervals: Review your Explorer maintenance schedule and address any upcoming services before winter.
• Professional Inspection: Consider a comprehensive pre-winter inspection by a certified Ford technician.
