Keeping the tire pressure within the manufacturer’s recommended range improves fuel efficiency, enhances vehicle handling, and ensures driver safety.
1.3 Inspecting Windshield Washer Fluid
Windshield washer fluid is essential for maintaining clear visibility by cleaning dirt and grime off the windshield. It also reduces friction between the wipers and glass, preventing scratches. To maximize windshield longevity and minimize light refraction issues, check and refill the washer fluid regularly.
1.4 Engine Maintenance: Every 3,000–5,000 km
The maintenance schedule for an engine varies depending on the vehicle manufacturer. However, a general rule is to service the engine every 3,000 - 5,000 km or every 3 - 6 months. For new cars, it is advisable to have an earlier service at 3,000 - 4,000 km or within the first 3 - 4 months to ensure the engine operates optimally in its initial phase.
1.5 Changing Engine Oil
Replacing engine oil helps remove contaminants and ensures smooth engine operation by reducing wear caused by friction between components. Vehicle owners should use the engine oil type recommended by the manufacturer for optimal performance.
1.6 Cleaning the Engine Air Filter
The engine air filter prevents dust and debris from entering the engine. A clogged filter reduces engine efficiency and increases fuel consumption. Additionally, a clean filter ensures accurate airflow sensor readings for optimal fuel combustion. Manufacturers recommend cleaning the engine air filter every 5,000 km and replacing it every 20,000 km. If driving in polluted environments, more frequent checks and cleaning are advised to maintain peak vehicle performance.
1.7 Checking the Cabin Air Filter
Though small, the cabin air filter plays a crucial role in maintaining clean air inside the vehicle. Regular inspection and cleaning remove accumulated dust, ensuring better air quality and preventing malfunctions. Manufacturers recommend cleaning the cabin air filter every 5,000 km. Additionally, inspecting related components such as the condenser, evaporator, and return air filter ensures a well-functioning air conditioning system.
2. Vehicle Maintenance Milestones for the Oil Filtration System (Every 5,000 - 10,000 km)
2.1 Oil Filter Replacement
The oil filtration system is often referred to as the "lungs" of a vehicle, as it removes dirt and impurities from the oil, ensuring proper lubrication and reducing engine wear. The engine contains many small metal channels that can become cracked or worn down if not properly lubricated. For regular vehicle maintenance, car owners should inspect and clean the oil filter monthly. If any damage is detected, replacement is necessary to ensure optimal engine performance.
2.2. Fuel Injector Inspection
Fuel injectors serve as a critical link in supplying fuel to the engine. To maintain smooth fuel delivery, injectors must be free from clogs and obstructions. Regular inspection and cleaning of fuel injectors help ensure stable engine operation. Manufacturers recommend cleaning fuel injectors every 15,000 – 20,000 km. However, if the vehicle operates in a polluted environment, earlier maintenance is advisable.
2.3. Tire Rotation & Balancing
Dynamic balancing ensures that the wheels remain stable, preventing vibrations in the steering wheel that could affect driving comfort. As a general rule, after every 6 months or 10,000 km, car owners should have their wheels balanced to prevent uneven tire wear. Additionally, tire rotation is recommended to promote even tread wear. The typical rotation pattern involves swapping the front right tire with the rear left and the front left tire with the rear right. Rotation should be performed every 8,000 – 10,000 km or every 6 months.
3. Cooling System Maintenance (Every 3 Years)
Car Maintenance Procedure for the Coolant Reservoir
The engine cooling system helps regulate the engine’s temperature to prevent overheating. It consists of two main types: air-cooled and water-cooled systems.
After 2 – 3 years, cooling systems may start releasing harmful substances that can corrode the exhaust pipes. Other issues, such as coolant leaks, strange noises, or high coolant temperature readings on the dashboard, may also arise. It is crucial to identify and address these problems promptly.
While cooling system cleaning can be done at home, it is time-consuming and requires precise execution to avoid damage. To ensure thorough maintenance, it is advisable to visit a professional auto service center. Additionally, coolant should be replaced every 80,000 – 100,000 km.
