What are the items included in the second maintenance of a car?

[Trevor]

Secondary maintenance mainly includes the following items: 1. Measure the cylinder pressure of the engine and adjust the valve clearance; clean various filters, oil pan, and the assembly of the oil collector. 2. Check and adjust the wear and clearance of connecting rod bearings; inspect and tighten the bolts of the front and rear engine brackets. 3. Check and adjust the brake, perform tire rotation; inspect the clutch and adjustments of other assemblies. 4. Extension: Secondary maintenance is generally performed when the car has traveled 6,000~8,000 km. The purpose of secondary maintenance is to ensure that the vehicle maintains good operating performance for a long period of time thereafter.

As someone who has driven for several years, I think the second maintenance is quite important. The key is changing the engine oil and oil filter to keep the engine running smoothly. It's also essential to check tire pressure and wear, and ensure the brake pads aren't too thin, otherwise braking performance suffers. Testing the lighting system, including headlights and turn signals, ensures nighttime safety. I always have them check the air filter—city driving gathers a lot of dust, and a dirty filter affects air intake. Suspension system inspection prevents excessive bumpiness, and a battery test prevents unexpected power loss. Regular second maintenance improves fuel efficiency and extends engine life. I recommend going to a 4S shop or a trusted repair shop for peace of mind.

I was quite excited when I got my first second maintenance shortly after buying the car. The core tasks were changing the engine oil and oil filter - basic upkeep. The technician checked tire wear and pressure, made sure the brake system was functioning properly, and tested all the lighting functions. They also inspected the air filter, replacing it if too dusty. The power steering fluid level and battery condition were checked too, to avoid breakdowns. I think it's good for new owners to bring the manual for reference. While dealerships sometimes recommend cleaning services, just choose what you need. The whole process was quick - spending a little money for greater peace of mind.

The core of the second car maintenance is to maintain key components. Changing engine oil and oil filters ensures engine lubrication and reduces wear. Focus on inspecting the braking system, including brake pads, fluid levels, and safety functions. Tire evaluation involves checking air pressure uniformity and tread depth, which affect grip. Lighting tests cover front and rear lights and signals to prevent accidents. Steering and suspension system checks maintain handling stability. Air filter replacement depends on road conditions and dust accumulation. These basic items should be performed according to the manual to avoid overlooking potential faults.

I always regard the second maintenance as a major safety inspection. It's essential to check braking performance, such as pad/rotor wear and hydraulic fluid levels. Tire condition affects braking distance and prevents skidding. Full lighting system tests ensure nighttime visibility. Battery voltage checks prevent sudden stalling. Suspension and steering system evaluations avoid loss of control risks. Doing these can reduce travel risks and protect occupants. I emphasize these items during every service - time-consuming but worthwhile.

To save money on the second maintenance, focus on the essentials: basic items like changing the engine oil and oil filter, checking tire pressure and brake wear. Ensure all lighting functions are working to avoid safety hazards. Replace the air filter based on usage conditions. Don't be tempted by additional lubrication or cleaning services. I refer to the user manual and only perform standard items. Simple checks on the battery and coolant can be done by myself. Keep costs within a reasonable range, and the car will be more durable after maintenance.
