What are the precautions for car maintenance?

Precautions for car maintenance include: 1. Air conditioning must be cleaned and maintained: In summer, the air conditioning operates under high load, and frequent rain means cars often drive through waterlogged roads, causing the lower part of the air conditioning condenser to accumulate mud and sand. Over time, this can lead to rust on the condenser, shortening its lifespan. Therefore, a thorough maintenance of the air conditioning system should be performed in autumn. Additionally, pay attention to the maintenance of the heater pipes and fan. As the weather cools in autumn, frost may appear when temperatures drop. During this season, it's crucial to ensure that the defrost vents below the windshield are functioning properly and providing sufficient heat. If any issues arise, they should be addressed promptly to avoid unsafe driving conditions. 2. Replace tires with shallow treads in time: High summer temperatures require frequent checks of tire pressure to prevent overinflation and blowouts. In autumn, as temperatures drop, tire pressure should be replenished to maintain it within the specified range. Also, inspect tires for scratches, as rubber tends to harden in autumn and winter, making tires more prone to leaks or punctures.
I've been driving for over a decade, and I believe the most crucial aspect of car maintenance is engine oil care. Change mineral oil every 5,000 km or full synthetic every 8,000 km – never exceed these intervals. Regularly check the dipstick yourself to ensure the oil level stays between the marks. Remember to change brake fluid every two years, as absorbed moisture can affect braking performance. Check tire pressure monthly, maintaining 2.3-2.5 when cold for optimal fuel efficiency. Switch to antifreeze windshield washer fluid before winter each year to prevent pipe freezing and cracking. Use pH-neutral car shampoo when washing, and limit waxing to once every three months. Never hose down the engine bay – clean it with a soft brush instead. Develop the habit of turning off the AC before shutting down the engine to prevent odors. Regular cabin air filter replacement benefits both your car's ventilation system and your respiratory health.
Daily car maintenance requires attention to these details: Wait 30 seconds after starting the engine in the morning before driving off, allowing the oil to lubricate. Avoid stomping on the accelerator when the engine is cold; wait until the coolant temperature gauge reaches the middle for normal operation. Disconnect the negative terminal of the battery if parking for more than two weeks to prevent power drain. Rotate the tires every 20,000 kilometers to ensure even wear on all four wheels. Don't wait until the fuel light comes on to refuel; the fuel pump relies on gasoline immersion for cooling. When washing the car, focus on rinsing the undercarriage to remove road salt and prevent corrosion. Avoid carrying heavy items in the trunk to save fuel and protect the suspension. Regularly open the windows for ventilation, especially in new cars to dissipate odors. Remember to clear the memory of the dashcam; it can provide crucial evidence when needed.
Money-saving car maintenance tips: Purchase your own engine oil and oil filter for maintenance, saving half on labor costs. Replace the cabin air filter yourself, available online for just 30-50 yuan. When buying insurance, don't just focus on price - pay attention to whether the third-party liability coverage is sufficient. Don't fill up the gas tank completely; filling three-quarters is most fuel-efficient. Use touch-up paint for small scratches as temporary solution, then repaint when multiple scratches accumulate. Repair reverse radar immediately if broken - replacing a fuse only costs a few yuan. Park in garages or shaded areas to avoid rapid aging from sun exposure. Replace wiper blades yourself for half the cost of replacing entire wiper arms. Get a car wash membership card to save 300-400 yuan annually.
