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

[EthanLee]

At 40,000 kilometers, car maintenance requires the replacement of engine oil, spark plugs, cabin air filter, engine air filter, oil filter, brake fluid, coolant, etc. In addition to some mandatory maintenance items, the 4S shop will determine whether parts need to be replaced based on the car's usage and the condition of the components. Relevant information about car maintenance is as follows: Introduction: Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. Maintenance Scope: Modern car maintenance mainly includes the maintenance scope of the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc.

I just completed my car's 40,000-kilometer maintenance, which feels like a small milestone. Changing the engine oil and filter is basic maintenance—don't skimp on this, or poor engine lubrication could lead to major issues. The air filter should also be checked or replaced; if it's dirty, it can affect the engine's air intake efficiency. Tires need careful inspection for pressure and wear—if the tread is too shallow, consider replacing them, as good traction is crucial in rainy conditions. Don’t overlook the braking system, especially brake pad thickness and brake fluid levels—safety comes first. It’s also a good idea to check the battery health and ensure all lights are working for safe nighttime driving. Coolant levels should be inspected to prevent engine overheating. I recommend getting a full diagnostic at a professional service center to extend your car's lifespan.

At 40,000 kilometers, maintenance should focus on safety. Key inspections include the braking system; brake pads should be replaced if excessively worn to avoid the risk of failing to stop in emergencies. Ensure tire pressure is appropriate, and uneven wear indicates the need for wheel alignment adjustment, which affects handling. Test all lights thoroughly, especially turn signals and headlights, to ensure safe nighttime driving. Don't overlook the engine oil and filters, as they are fundamental to engine health. Check the battery voltage for signs of discharge and ensure the coolant level is adequate. Paying attention to these details can prevent unexpected breakdowns and ensure a more secure driving experience.

I'm used to only doing necessary maintenance at this mileage. Oil and filter changes are essential to keep the engine running smoothly. If the air filter isn't too dirty, you can delay replacing it to save money. Brake pads can wait if they're not heavily worn. Just maintain standard tire pressure yourself—no need for excessive spending. Remember this tip: Learn some self-inspection skills, like checking battery health with a multimeter, so you don't have to rely on shops for everything.

I usually enjoy checking my car's condition by myself. At 40,000 kilometers, I first measure the tire pressure to ensure even wear and avoid accidents. Checking brake pad thickness with tools is simple; using calipers is convenient and accurate. I test battery health with a voltmeter - too low a reading indicates potential issues. I remove and clean the air filter to save on replacement costs. While I leave oil changes to professional shops, preliminary self-checks can save money and teach valuable skills.
