What are the items for the second car maintenance?

Generally, during the second car maintenance, items such as engine oil, oil filter, air filter, and cabin air filter are replaced. The second maintenance is relatively simple, but it also involves checking the condition of various fluids and the working state of wearable parts. The fluids in a car include engine oil, coolant, brake fluid, power steering fluid, and transmission fluid. The wearable parts include belts, various filters, wipers, tires, brake pads, brake discs, spark plugs, ignition coils, etc. More details are as follows: 1. During maintenance, fluids and wearable parts are replaced, and other wearable parts are inspected. 2. It is recommended to measure the water content in the brake fluid during each maintenance, as brake fluid is highly prone to absorbing water. If the water content in the brake fluid reaches 3%, it should be replaced immediately; otherwise, it can lead to reduced braking force and longer braking distances. Tires are usually replaced every four years, as they are rubber products and can deteriorate over time. If the mileage is low within four years, replacement is still necessary. Spark plugs also require regular replacement; failure to replace them in time may affect the engine's performance.
For the second car maintenance, I usually arrange it like this: Changing the engine oil is a must, as it lubricates the engine and reduces wear; the oil filter is replaced at the same time to ensure cleanliness. Check the air filter and replace it if it's dirty, otherwise it may affect performance; also check the cabin air filter to see if it needs replacement to ensure good air quality inside the car. Tires are a key inspection item, including tire pressure adjustment and wear check to maintain smooth and safe driving; test the brake system for responsive reaction to avoid sudden brake failure. Check the suspension components for looseness; ensure all lights and signals are functioning properly to prevent hazards during night driving. Check the coolant level to avoid overheating; briefly inspect the undercarriage for any scratches. It usually costs a few hundred bucks, and I choose authorized service centers for maintenance as appointments are convenient and time-saving.
During my last second maintenance, I specifically requested a comprehensive inspection of safety-related components: checking if the brake discs and pads were worn out and replacing them in time to ensure reliable emergency braking; measuring tire tread depth and balancing to prevent the risk of blowouts; inspecting the chassis and suspension system for looseness to ensure stable cornering. The oil filter was replaced to avoid carbon buildup; the air filter was checked and replaced if dirty to ensure fresh air intake. All lighting signals were tested to ensure visibility during dusk driving. The coolant was topped up to prevent engine overheating. A brief check was also done on electronic systems like ABS to ensure normal operation. The cost was around 400 yuan, which I accepted for the peace of mind when driving with my family on trips without worries.
