What Maintenance Should Be Done When a Car Reaches 40,000 Kilometers?

The 40,000-kilometer maintenance for a vehicle is considered a major service. The primary maintenance tasks include replacing the engine oil, three filters, and all vehicle fluids, along with necessary routine inspections such as changing the brake fluid, transmission fluid, power steering fluid, and coolant. Below are the relevant details: In addition to the main maintenance items, it is also necessary to check the wear of the brake pads, inspect tire wear and tire pressure, and assess the aging and wear of rubber components like the engine's external belts. Additionally, check for any oil leaks in the engine, transmission, and shock absorbers. Depending on the vehicle's usage, inspect the carbon buildup in the intake and exhaust systems. If necessary, perform cleaning and maintenance on the exhaust system, which generally includes cleaning the fuel injectors, throttle idle valve, intake manifold, and three-way catalytic converter.
My car has just passed 40,000 kilometers, and this maintenance milestone is crucial because the engine is prone to carbon buildup. I usually start by changing the engine oil and oil filter to ensure good lubrication and extend the engine's lifespan. At the same time, I check the air filter and replace it if it's dirty to avoid affecting air intake efficiency. It's also time to replace the spark plugs, as faulty ignition can lead to increased fuel consumption or difficulty starting. Don't forget to inspect the braking system, including the wear level of the brake pads and the condition of the brake discs—safety comes first. The tires should be rotated and balanced to prevent uneven wear and reduce wear rates. The coolant should also be refreshed to ensure proper cooling. For automatic transmission vehicles, check the transmission fluid level. Additionally, have a mechanic inspect the suspension and exhaust system to prevent minor issues from becoming major problems. After this maintenance, the car will run smoother and safer.
I've been doing my own car maintenance for a few years now. At 40,000 kilometers, I prioritized the simpler tasks. Buying quality engine oil and filters made the oil change process quite straightforward; the air filter is easily replaced by just opening the hood. Spark plugs can also be changed if you have the right tools, but always check the manual first to avoid getting the wrong model. Rotating tires is something you can do by just pushing the wheels, but balancing should be left to the shop to save money. Brake inspections are best handled by professionals for safety; coolant can be extended if it's not cloudy, but it's better to replace it. I also regularly check the cabin air filter and replace it myself to prevent odors. To save money, I often buy parts online, but never skimp on critical components like engine oil. After maintenance, the car runs better, and I've grown to enjoy the hands-on experience.
As a new car owner, I asked the mechanic what needs to be done when the car reaches 40,000 kilometers. It's essential to change the engine oil and oil filter to keep the engine running smoothly; check the brake pad thickness—safety should never be compromised. Inspect tire wear and consider rotation to extend their lifespan. Replace spark plugs to prevent ignition issues; if the cabin air filter is clogged, replace it for fresher air. Test the coolant condition and replace if necessary. Also, pay attention to other items like transmission fluid inspection or fuel filter replacement. Most importantly, follow the guidelines in the owner's manual, and if unsure, consult the repair shop directly—don't delay maintenance to avoid breakdowns on the road.
