What maintenance should be done for a car with 70,000 kilometers?

For a car with 70,000 kilometers, the following maintenance should be performed: 1. Consider replacing the tires. When a car reaches over 70,000 kilometers, the tire tread is usually severely worn, and the rubber may have aged. For driving safety, it is recommended to replace the tires. 2. Replace the transmission fluid. Transmission fluid has a usage cycle and generally needs to be replaced every 2 years or 40,000 kilometers. 3. Clean the three-way catalytic converter. As the vehicle's mileage increases, carbon deposits from the engine can clog the three-way catalytic converter, leading to poor acceleration and failing emission standards. The cleaning cycle for the three-way catalytic converter is typically every 30,000 to 40,000 kilometers. It is recommended to clean it at this point. 4. Inspect the vehicle's suspension and various rubber bushings. These rubber bushings play a role in supporting and stabilizing the vehicle's engine. Over time, rubber aging can cause various noises from the chassis while driving. Therefore, it is recommended to inspect the suspension system.
I've been driving for over ten years, and 70,000 kilometers is a critical milestone for a car. This maintenance needs to be thorough—engine oil and oil filter must be replaced, and remember to check if the air filter needs changing; if you drive mostly in the city, it's probably clogged by now. The spark plugs should be replaced too, otherwise, poor ignition will affect fuel efficiency. Brake fluid and coolant are also recommended for replacement—they degrade after a couple of years, so don’t skimp on these. Check the tires; if there’s significant wear difference between the front and rear, rotate them. If the tread depth is insufficient, it’s time for new tires. Finally, have the technician thoroughly inspect the suspension bushings—at this mileage, rubber components are likely aged. Replacing suspension bushings only costs a few hundred bucks but makes a noticeable difference in noise reduction over speed bumps.
My car just had its 70,000-kilometer maintenance, and I have some deep feelings about it. Don't just focus on changing the engine oil; the transmission fluid must be replaced. For automatic transmission cars, the fluid oxidizes after 70,000 kilometers, and if not replaced, it will cause gear shift jerks and increased fuel consumption. It's best to check the belt for cracks—if it breaks, you'll need a tow. Many people overlook the fuel filter, but gas station fuel quality can be unpredictable. Measure the brake pad thickness and replace them if they're thin—last time, I wore them down to the metal and had to spend a lot on brake disc repairs. Small items like wiper blades should be replaced as a matter of course; visibility in the rain is crucial for safety. Cleaning the cooling system isn't expensive, and older cars are prone to overheating.
