What maintenance is required for a car at 40,000 kilometers?

[SanIker]

At 40,000 kilometers, car maintenance includes replacing engine oil, oil filters, spark plugs, etc. Below is a detailed introduction to the car maintenance items: Engine Oil and Oil Filter Replacement: This primarily involves maintenance for the lubrication system. The main function of the lubrication system is to effectively lubricate various components of the car engine. Under normal circumstances, the car should be serviced every 5,000 kilometers. Replacing the air filter is necessary as its role is to filter air before it enters the cylinders, removing impurities, dust, sand, and other foreign particles. Spark Plug Replacement: Spark plugs are consumable items and should be replaced every 20,000 kilometers. Additionally, components such as brake fluid, transmission oil, battery, throttle, fuel injectors, and brake pads are part of the inspection items during routine maintenance, and their maintenance should be carried out based on usage conditions.

Every time my car reaches 40,000 kilometers, I take it in for maintenance, primarily to change the engine oil and oil filter. This is the most basic upkeep to keep the engine lubricated and reduce wear. At the same time, I have the brake system checked to see the wear level of the brake pads and if the discs need adjustment, to avoid failure at critical moments. Tires are also crucial; I check the tread wear and ensure the tire pressure is even, rotating them if necessary to extend their lifespan. The air filter is usually replaced with a new one to improve air intake efficiency and save on fuel consumption. If the spark plugs haven't been changed yet, they should be checked as well, as too large a gap can affect starting performance. The coolant and antifreeze levels need to be topped up to prevent overheating issues. I perform these maintenance tasks regularly, which makes the car run more smoothly, with lower fuel consumption and less noise, saving on future repair costs. Typically, it takes about two hours to complete.

After my car exceeds 40,000 kilometers, I will focus on preventive maintenance. Changing the engine oil is a routine operation, combined with a new filter to extend the engine's lifespan. Checking the spark plugs is crucial; replacing them when there's too much carbon buildup can improve ignition efficiency. For the braking system, I carefully inspect the wear on the discs and pads—if they're too thin, they need to be replaced promptly for both cost savings and safety. Regarding tires, I check for wear and balance, adjusting the tire pressure to reduce bumps. Cleaning or replacing the air filter ensures smooth airflow, making driving more fuel-efficient. For the cooling system, I check the coolant level to avoid corrosion and damage to the pipes. If there's any unusual noise from the belt, I make sure to inspect it to prevent breakage. A quick check on the suspension ensures the shock absorbers are working properly for a smooth ride. This kind of maintenance helps avoid breakdowns and saves money and hassle. I often handle some DIY projects myself.

At the 40,000-kilometer maintenance, I always emphasize safety first. Checking the braking system is crucial; excessive wear on discs and pads that affects braking distance must be addressed. Inspecting tire wear and pressure ensures good traction and reduces the risk of skidding. Testing the brightness of headlights and taillights guarantees visibility at night. Replacing engine oil and filters is essential to lubricate the engine and prevent malfunctions. A dirty air filter should be replaced to improve air intake quality. If necessary, replacing spark plugs optimizes starting speed. Topping up the coolant level prevents overheating issues. Completing these basic checks ensures a safer drive with fewer breakdowns.
