What Maintenance Items Are Needed for a Car at 70,000 Kilometers?

At 70,000 kilometers, the maintenance items for a car include: replacing various belts, changing the transmission fluid, replacing spark plugs, cleaning the throttle body and fuel injectors, cleaning the catalytic converter, replacing the fuel filter, and more. It is also necessary to inspect the vehicle's suspension, various rubber bushings, and tire condition, replacing them if necessary. When a car reaches 70,000 kilometers, the tire tread is usually significantly worn, and the rubber may have aged. For driving safety, it is recommended to replace the tires if needed. Here is some information about car maintenance: 1. Inspect the vehicle's suspension and various rubber bushings. These bushings play a stabilizing and supporting role under the vehicle's engine. Over time, the rubber ages, and the chassis may produce various abnormal noises while driving. 2. Various belts in the car should generally be replaced every 2 years or 60,000 kilometers. Belts are rubber components and may develop cracks with prolonged use. It is advisable for owners to replace them in advance to avoid affecting the vehicle's normal operation. 3. Spark plugs are consumable items and should be replaced every 20,000 kilometers. Additionally, components such as brake fluid, the battery, throttle body, fuel injectors, and brake pads are inspection items during maintenance, and their servicing should be based on usage conditions.

Last time when my car reached 70,000 kilometers, I did a comprehensive maintenance. In addition to the basic oil and filter change, the focus was on checking the brake pad wear since safety comes first. The transmission fluid needed replacement as not changing it for too long can cause gear shifting hesitation. The mechanic also replaced the spark plugs for me, and upon removal, it was found that the electrodes were all eroded. The tires had to be carefully inspected, and a nail was almost missed in my left front tire. The antifreeze was also tested for its freezing point, and half a liter was topped up. Finally, the throttle body was cleaned, and it was full of oil sludge and carbon deposits when opened. It's recommended to drive at high speeds after maintenance to clear out the carbon deposits.

70,000 kilometers is considered a major maintenance milestone. Basic items like engine oil and oil filter are essential. Special attention should be paid to the braking system: How much thickness is left on the brake pads? Has the brake fluid deteriorated? Diagonal tire rotation is crucial. Both the air filter and cabin air filter must be replaced. Don't forget to inspect chassis components such as the control arm bushings. Spark plugs should be replaced between 60,000 to 80,000 kilometers, especially for direct injection engines. The manufacturer recommends changing the transmission fluid at 60,000 kilometers, and you've definitely exceeded that mileage. It's advisable to set aside half a day to thoroughly inspect the chassis suspension and steering system.

At the 70,000-kilometer maintenance, the service mainly consists of three parts. First, engine-related tasks: replace the full synthetic oil and oil filter, replace the spark plugs, and inspect the belts. Second, the fluid systems: the transmission fluid must be replaced, the brake fluid needs to be tested, and the coolant level should be checked. Third, consumable parts: rotate the tires, check the thickness of the brake pads, and replace the air and cabin filters. Special reminder: inspect the chassis bushings, as aging rubber components may cause unusual noises. Finally, remember to have the mechanic scan the ECU for fault codes.

The 70,000-kilometer maintenance is essentially preventive maintenance. Basic maintenance like changing the engine oil and oil filter is a must. The most important thing is to inspect all rubber components in the vehicle: engine mounts, suspension bushings, etc., as aging can cause abnormal noises. For the drivetrain, it's essential to change the transmission fluid, especially for CVT and dual-clutch transmissions. Brake pads should be replaced when necessary—don't wait until they're worn down and damage the rotors. Check the tire tread depth and for any bulges. Additionally, it's recommended to perform an intake system cleaning, as carbon buildup on the throttle body can increase fuel consumption.

70,000 km maintenance emphasizes systematic care. Oil and oil filter changes are the most basic, with full synthetic being the recommended choice. The three major fluids are crucial: transmission fluid often appears black when drained, brake fluid may exceed water content limits, and coolant requires freeze point testing. For wear items, check tires for uneven wear, and brake pads become risky if thinner than 3mm. Hidden items demand attention: inspect ball joint and bushing clearance in the chassis, test battery lifespan, and examine alternator belt for cracks. Finally, a wheel alignment is absolutely worthwhile—it completely resolves steering wheel vibration.
