CAR GENERAL MAINTENANCE
Getting Your Vehicle Ready for Winter
Winter conditions can exacerbate existing vehicle problems, making preventive maintenance essential for safety and reliability. Proper care during the colder months can help avoid mechanical failure, improve vehicle longevity, and increase resale value. Here are key maintenance tips to prepare your vehicle for winter:
Engine Performance
- Getting Your Vehicle Ready for Winter
- Getting Your Vehicle Ready for Summer
- Keeping Your Vehicle in Tune with the Environment

Engine Performance
- Address drivability issues (e.g., hard starts, rough idling, stalling) before winter, as cold weather can worsen these problems.
- Replace filters (air, fuel) regularly to maintain optimal engine performance.
Fuel System
- Add fuel de-icer to your tank monthly to prevent moisture from freezing in the fuel lines. Keeping your gas tank full reduces the chance of moisture buildup.
Oil
- Change oil and filter according to the manufacturer’s recommendation—more frequently if you often drive in stop-and-go traffic or take short trips.
Cooling System
- Flush and refill your cooling system every 24 months, ensuring the coolant mix is at the recommended 50/50 ratio. Regularly check the coolant’s condition, and never open the radiator cap while the engine is hot.
Windshield Wipers
- Replace wipers and use winter-grade blades if your area experiences icy conditions. Keep a good stock of windshield washer solvent, as it’ll be used frequently during the winter.
Heater/Defroster
- Ensure that your heater and defroster are functioning properly to maintain comfort and visibility. For newer vehicles, check if the cabin air filter needs replacing.
Battery
- Regularly clean battery terminals and connections, checking the fluid level if possible. A weak battery may fail in cold weather, so get it tested with professional equipment.
Lights
- Check and replace burnt-out bulbs. Clean lenses to improve visibility, but avoid using dry rags to prevent scratches.
Exhaust System
- Have your exhaust system inspected for leaks to prevent harmful fumes from entering the cabin.
Tires
- Inspect tires for adequate tread and signs of wear. Cold weather can reduce tire performance, so ensure your tires are properly inflated (check when tires are cold) and replace worn tires as needed. Remember to check your spare tire.
Emergency Gear
- Carry emergency supplies: gloves, boots, blankets, sand or kitty litter, a flashlight, and snacks.

GENERAL MAINTENANCE
Getting Your Vehicle Ready for Summer
Summer conditions, including heat, dust, and stop-and-go driving, put a strain on your vehicle. Performing maintenance before summer arrives can help avoid breakdowns, ensure efficiency, and extend the vehicle’s life.
Air Conditioning
- Have the A/C system checked by a qualified technician to ensure it operates efficiently. Replace the cabin air filter if your vehicle has one.
Cooling System
- Ensure the cooling system is functioning properly to prevent overheating. Flush and refill every two years or 30,000 miles, and check coolant levels regularly.
Oil
- Change oil and oil filters regularly, particularly if your driving involves frequent short trips or towing.
Engine Performance
- Replace other filters (air, fuel, PCV) and address engine issues such as rough idling or diminished power before the heat of summer arrives.
Windshield Wipers
- Replace worn blades and stock up on windshield washer solvent for clean visibility, especially during summer rains.
Lights
- Regularly check all vehicle lights and replace burned-out bulbs. Clean any dirt or insects from lenses to maintain visibility.
Tires
- Rotate tires every 5,000-6,000 miles. Check for uneven wear, sidewall damage, and proper inflation. A misalignment can cause uneven tire wear.
Brakes
- Inspect the brake system for wear and tear. If you experience brake issues (e.g., pulsations, noises), get them addressed promptly.
Battery
- Clean battery connections and check the fluid level monthly. Get the battery tested by a professional if it’s showing signs of weakness.
Emergencies
- Carry basic tools (check with a professional technician for suggestions) along with first aid supplies, flares, and a flashlight.
Keeping Your Vehicle in Tune with the Environment
Proper maintenance not only benefits your vehicle but also the environment. Here are some eco-friendly car care tips:
Engine Maintenance
- Keep your engine tuned and replace spark plugs and filters as per the manufacturer’s guidelines. A misfiring spark plug can reduce fuel efficiency by up to 30%.
Tire Inflation
- Ensure tires are properly inflated to avoid excess fuel consumption. Underinflated tires reduce efficiency and tire life, and misaligned wheels make the engine work harder.
Air Conditioner Care
- Have your A/C system serviced by a qualified technician. CFCs from A/C systems contribute to ozone depletion, so it’s important to choose a certified technician who handles refrigerant recycling properly.
Waste Disposal
- Dispose of used motor oil, coolant, tires, and batteries responsibly. Many repair facilities accept these items, or local municipalities may offer recycling programs.
Driving Habits
- Observe speed limits (fuel efficiency drops above 55 mph) and drive gently to reduce fuel consumption. Avoid excessive idling, and plan trips to reduce unnecessary driving and congestion.
Weight Reduction
- Remove excess weight from your vehicle. The less weight it carries, the better its fuel efficiency. Avoid carrying luggage on the roof to reduce air drag.
By preparing your vehicle for both winter and summer conditions, you ensure its longevity, performance, and environmental impact. Regular maintenance will keep your vehicle running smoothly, while responsible driving and disposal practices can make a positive difference to the environment.
