What Maintenance Does a Car Need After Four Years?
3 Answers
For a car that has been used for four years, the maintenance items that need attention include engine oil, the three filters (air filter, oil filter, and fuel filter), cabin air filter, brake fluid, coolant, transmission fluid, and spark plugs. These components generally require replacement. Additionally, it's important to inspect wear-and-tear items such as car tires and window seals. Among these, brake fluid and transmission fluid are particularly crucial. Consequences of Not Adding Brake Fluid Timely: Failure to replenish brake fluid promptly can lead to severe safety hazards, potentially endangering the lives of passengers. Therefore, brake fluid must never be overlooked. Consequences of Not Changing Transmission Fluid: If the car has been driven for an extended period or exceeds 60,000 kilometers, regular transmission fluid replacement is necessary. Deteriorated transmission fluid can result in difficulty shifting gears and wear on transmission bearings. Important Notes: A major maintenance service is typically required after several years of use or when the mileage approaches 100,000 kilometers (some cars may need it at 60,000 kilometers). A comprehensive inspection should be conducted, and parts should be replaced as needed. The car's drivetrain is the most critical system—damage to it can have serious consequences. Additionally, the electrical system in older cars is prone to aging, loosening, or detachment, which plays a vital role in vehicle safety.
My car has been driven for four years, and at this stage, several key maintenance items are generally required. Changing the engine oil and oil filter is the most basic; it should be done every 5,000 to 10,000 kilometers to protect the engine from excessive wear. The air filter should also be inspected or replaced, as a dirty one can affect air intake and fuel consumption. Don’t overlook the braking system—after four years, the brake pads may have worn thin, so have a technician check if they need replacement. Also, replace the brake fluid to ensure responsive braking. Assess the tire wear; shallow treads can lead to skidding, and regular tire pressure checks can extend their lifespan. The coolant should be replaced every few years; otherwise, engine overheating can cause major issues. Belts and hoses may have aged and could crack, so a comprehensive inspection is necessary. The battery, after four years, is nearing the end of its life—test its voltage to see if it needs replacement. It’s advisable to visit a professional shop for a full-service package; spending a little now can prevent major repairs later.
As a stay-at-home dad, I place great emphasis on the safety maintenance of a four-year-old car. My top priorities are the brakes and tires—checking the thickness of the brake pads and the condition of the brake fluid, and replacing the fluid to prevent brake failure. If the tire treads are worn down, replace them promptly to avoid skidding in rainy conditions. The battery is the heart of the car and tends to lose charge after four years, so test its performance and replace it if necessary. Don’t overlook the cooling system; replace the coolant to prevent engine overheating and potential breakdowns. Interior components like seat belts and lights should also be inspected to ensure clear visibility for nighttime driving. To keep my family safe on the road, I make it a habit to perform these basic checks every six months—delaying them increases risks.
