Tire Rotation
Tires wear unevenly due to various factors like vehicle alignment, driving habits, and tire position (front vs. rear). Rotating your tires at recommended intervals helps equalize tread wear, extending their lifespan and preventing noise and vibration issues. Tire rotation is a key aspect of tire maintenance and contributes to better handling and a smoother ride. Consult your owner’s manual or a tire professional for the recommended tire rotation schedule for your vehicle, typically every 5,000 to 7,000 miles.

Regularly checking and replacing the transmission fluid as recommended by your vehicle manufacturer is crucial to avoid costly transmission repairs or replacements. Refer to your owner’s manual for the recommended service intervals for your specific vehicle and transmission type.
Transfer Case Fluid
For vehicles equipped with four-wheel drive (4WD) or all-wheel drive (AWD), the transfer case is a critical component that transfers power from the transmission to the front and rear axles. Like transmission fluid, transfer case fluid requires periodic checks and changes to ensure proper lubrication and prevent damage. Check your vehicle manufacturer’s recommendations for the appropriate service intervals for your transfer case fluid. This often requires accessing the underside of the vehicle, so professional service is typically recommended.
Inspect Shocks and Struts
Shocks and struts are vital components of your car’s suspension system. They control the impact and rebound of the wheels as you drive over bumps and uneven road surfaces, contributing to ride comfort, handling, and braking stability. Worn shocks and struts can compromise ride quality, handling, and tire wear. It’s recommended to have them professionally inspected around every 50,000 miles or sooner if you notice signs of wear, such as excessive bouncing, poor handling, or uneven tire wear.
Coolant Fluid Exchange (Radiator Flush)
The coolant system, including the radiator, is essential for regulating engine temperature and preventing overheating. Over time, coolant can become contaminated and lose its effectiveness, potentially leading to corrosion and engine damage. A coolant fluid exchange, often referred to as a radiator flush, involves draining the old coolant, flushing the system, and refilling it with fresh coolant. This service helps remove contaminants and ensures the cooling system functions optimally. Consult your vehicle manufacturer’s recommendations for coolant exchange intervals.
Spark Plugs
Spark plugs are crucial for igniting the air-fuel mixture in your engine’s cylinders, initiating the combustion process that powers your vehicle. Worn or fouled spark plugs can lead to reduced engine power, decreased fuel efficiency, and misfires. Depending on your vehicle and spark plug type, they typically need replacement at intervals specified in your owner’s manual, often ranging from 30,000 to 100,000 miles. If you experience a decrease in engine performance or fuel economy, it might be time to have your spark plugs inspected and replaced.
Serpentine Belt
The serpentine belt is a single, long belt that drives multiple engine accessories, including the alternator, power steering pump, and air conditioning compressor. This belt is crucial for these systems to function correctly. A cracked, worn, or broken serpentine belt can lead to the failure of these essential systems, potentially causing breakdowns. Visually inspect the serpentine belt for cracks, fraying, or damage regularly. Replace it if damage is evident or according to your vehicle manufacturer’s recommended schedule.
Front and/or Rear Differential Fluid
Differentials are gear systems that allow the wheels on an axle to rotate at different speeds, which is essential for smooth cornering. Front-wheel drive and rear-wheel drive vehicles have one differential, while 4WD and AWD vehicles have both front and rear differentials, and sometimes a center differential. Differentials require lubrication to function properly and prevent wear. Differential fluid should be checked and changed according to your vehicle manufacturer’s recommendations, typically less frequently than engine oil. This service usually requires professional attention.
Seasonal Car Maintenance Checks
Your car’s maintenance needs can also vary with the seasons and driving conditions. Consider these seasonal checks to ensure your vehicle is prepared for changing weather.
Replace Windshield Wipers
Windshield wipers are essential for maintaining clear visibility in rain, snow, and other inclement weather. Wiper blades wear out over time due to exposure to the elements and use. Replace your windshield wipers approximately every year, or sooner if you notice streaking, skipping, or reduced cleaning effectiveness. In winter, consider installing winter wiper blades designed to perform better in snow and ice. Lifting wipers away from the windshield in winter can prevent them from freezing to the glass.
Battery Performance Check
Car batteries are susceptible to extreme temperatures, both hot and cold. Extreme temperatures can impact battery performance and lifespan. Regular battery testing, especially before winter and summer, can help ensure your battery is in good condition and will reliably start your vehicle. A battery performance check can identify a weak battery before it fails unexpectedly.
Change Tires (Seasonal Tire Change)
If you live in an area with significant winter weather, consider switching to winter tires during the colder months. Winter tires are designed with specialized rubber compounds and tread patterns that provide superior traction in cold temperatures, snow, and ice compared to all-season tires. When temperatures consistently drop to freezing or below, the rubber in all-season tires hardens, reducing grip. Winter tires remain more flexible in cold weather, enhancing safety and control in winter driving conditions. Change back to your regular tires when temperatures consistently warm up in the spring.
Check Coolant/Antifreeze Levels (Winter Specific)
In winter, it’s particularly important to check your coolant’s antifreeze concentration. Antifreeze prevents the coolant from freezing in cold temperatures, which can cause serious damage to your radiator and engine. A 50/50 mix of antifreeze and water is generally recommended for most climates, but consult your owner’s manual or a professional for the specific recommendation for your vehicle and climate. Using a coolant tester can help determine the freeze protection level of your coolant.
Adhering to a consistent car maintenance schedule and keeping records of your maintenance activities is a proactive approach to vehicle ownership. It not only extends the life of your car and helps maintain its performance but also minimizes the risk of breakdowns, costly repairs, and unexpected issues, ensuring a safer and more reliable driving experience.
