Check the tire pressure at least once a month and adjust according to the manufacturer’s recommendations, usually found on a label inside the driver’s side door.
Tire Rotation: Tires wear unevenly based on your driving habits and the weight distribution of your vehicle. To ensure even wear, rotate your tires every 6,000 to 8,000 miles or as your car’s manual recommends.
Alignment and Balance: Misalignment can lead to uneven tire wear and poor handling. If you notice your car pulling to one side or the steering wheel feeling off-center, it’s important to have its alignment checked. Proper wheel balancing also ensures smooth driving and prevents premature tire wear.

2.3 Brake System Care

Brakes are one of a vehicle’s most vital safety features. Modern brake systems use various technologies, including anti-lock braking systems (ABS), electronic brake-force distribution (EBD), and traction control. Regular maintenance of your brakes is essential to keeping your car safe to drive.

Brake Fluid: Brake fluid is essential for the operation of the braking system. It allows the force you apply to the brake pedal to be transmitted to the wheels. It’s important to check the brake fluid levels and replace them according to the manufacturer’s recommendations.
Brake Pads and Rotors: Brake pads wear down over time as they come into contact with the rotors. If you hear a squealing noise or braking becomes less responsive, it may be time to replace the pads. If you’re unsure about the condition of your brake system, it’s always a good idea to contact a mechanic for a thorough inspection. The rotors should also be inspected for wear and tear, as damaged rotors can affect braking performance.

2.4 Battery Care

The car battery powers essential components like the lights, radio, and electronics. A dead or weak battery can leave you stranded, so it’s important to check and maintain the battery regularly.

Inspecting the Battery: Check for any corrosion around the battery terminals, as this can impede the flow of electricity. Cleaning the terminals can help ensure the battery works efficiently.
Battery Replacement: Batteries typically last between three to five years, depending on factors like climate and usage. If your battery is nearing the end of its life or showing signs of weakness (e.g., slow engine cranking), consider replacing it.

2.5 Fluid Levels

Cars rely on several fluids to operate correctly, including engine oil, coolant, transmission fluid, power steering fluid, and windshield washer fluid. Ensuring these fluids are at the proper levels and in good condition is essential for smooth operation.

Engine Coolant: The coolant system helps regulate the engine’s temperature. Low coolant levels can cause overheating and severe engine damage. Check coolant levels regularly, especially before long trips.
Transmission Fluid: Transmission fluid lubricates the gears and helps prevent overheating. Depending on your vehicle’s make and model, transmission fluid should be checked and replaced periodically.
Power Steering Fluid: If your steering wheel becomes stiff or rigid to turn, it may be a sign that your power steering fluid is low. Regularly checking and topping off this fluid can help avoid steering issues.
Windshield Washer Fluid: Top off the windshield washer fluid to ensure your wipers perform optimally, especially during inclement weather.

2.6 Air Filter Replacement

The air filter is essential in maintaining engine efficiency. It prevents dirt and debris from entering the engine and ensures the proper airflow to optimize combustion.

When to Replace: A clogged air filter can reduce fuel efficiency and engine performance. Most modern vehicles recommend replacing the air filter every 12,000 to 15,000 miles, varying depending on driving conditions (e.g., driving in dusty areas).

2.7 Timing Belt and Serpentine Belt

The timing and serpentine belts are essential for maintaining engine operation and running auxiliary components like the alternator, air conditioning, and power steering.

Timing Belt: The timing belt ensures synchronization of the engine’s valves and pistons. If it breaks, it can cause catastrophic engine damage. Most manufacturers recommend replacing it every 60,000 to 100,000 miles.
Serpentine Belt: The serpentine belt drives essential systems like the alternator and air conditioning. It should be inspected for wear and replaced if any cracks, fraying, or glazing are visible.

2.8 Windshield Wipers and Headlights

Visibility is key to safe driving, so it’s essential to maintain your vehicle’s wipers and headlights.

Wiper Blades: Wiper blades should be replaced at least once a year or more frequently if they begin to streak or make noise. This ensures clear visibility, especially during rain or snow.
