What Does the Second Maintenance of a Car Include?
2 Answers
Here is an introduction to the contents of a car's second maintenance: 1. Engine: After performing the 'three cleans and three filters' on the engine, it should ensure that the engine starts easily, runs smoothly, meets exhaust emission standards, and shows no abnormal noises, water leakage, oil leakage, electrical leakage, or air leakage. 2. Steering: The free travel and toe-in should meet the requirements, with light and flexible steering, and no wobbling or deviation of the front wheels during driving. 3. Clutch: It should be easy to operate, fully disengage, engage smoothly, with no abnormal noises, and no oil leakage in the hydraulic system. 4. Check the transmission, drive, and front half-shaft: Ensure good lubrication, reliable connection, easy gear shifting, and no oil leakage. 5. Check the brake pedal and service brake: The braking performance should be good, with no deviation or oil leakage, and the inertia proportioning valve should work normally. 6. Tire pressure: The tire pressure should be normal (the same as the high and low-pressure standards specified for the same model). 7. Accessories: The generator, starter, lights, instruments, signal lights, buttons, switches, and other accessories should be complete, intact, and functioning normally.
I've been driving for several years, and I remember every second maintenance clearly. It usually includes changing the engine oil and oil filter, which are the basics to keep the engine lubricated and cool. The air filter needs to be checked and replaced if it's dirty, otherwise it affects the air intake efficiency. The tires must be checked for pressure and wear level—I've measured them myself, and large deviations can impact fuel consumption and safety. The brake system is inspected for pad thickness and fluid level, which are crucial for emergency stops. They also check the lights, battery connections, coolant condition, and the tightness of chassis screws. Additionally, they listen to the engine sound and clear any fault codes. The second maintenance is like a mini health check—neglecting it can easily lead to malfunctions, so I recommend going to the 4S shop on schedule, which can extend the car's lifespan by over five years. The cost is usually a few hundred bucks, and it's worth it.
