What maintenance items does a car with 70,000 kilometers need?
4 Answers
A car with 70,000 kilometers requires a major maintenance service, including the replacement of all fluids. Objectives of car maintenance: The purpose of car maintenance is to keep the vehicle clean, maintain normal technical conditions, eliminate potential hazards, prevent failures, slow down the deterioration process, and extend the service life. Modern car maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and other maintenance areas. Precautions for car maintenance: The car maintenance cycle refers to the interval mileage or time for maintenance. A high maintenance frequency is not a bad thing; it can more effectively ensure the performance of the vehicle. In the early stages of vehicle use, the focus is on regular maintenance, with relatively low costs. When the vehicle reaches a certain age or mileage, it enters the repair period, and the costs become relatively higher. However, when determining the car maintenance cycle, it is advisable to refer to the maintenance cycle recommended by the car manufacturer, combined with the vehicle's own technical condition and actual usage conditions, to make appropriate adjustments to the maintenance cycle.
My car just passed the 70,000 km maintenance, and I have to say the focus at this stage is on checking several major components. Besides the regular oil and oil filter change, it's best to replace the spark plugs, as their lifespan is around 60,000-80,000 km. After replacement, the power response becomes more sensitive. The brake pads and brake discs also need to be measured for thickness—if they're severely worn, replace them immediately to ensure braking safety. Tire wear inspection is a must, and a wheel balance will make long-distance driving more stable. Check the expiration dates of the coolant and brake fluid; replace them if expired to prevent engine overheating or brake failure. Clean or replace the air filter and fuel filter to avoid dust clogging, which affects fuel consumption. Last time I ignored these, the spark plugs failed, leading to high fuel consumption. I recommend a comprehensive check every 10,000 km—it saves money and gives peace of mind.
After running 70,000 kilometers, maintenance should consider the transmission and electrical systems. Automatic transmission vehicles especially need transmission fluid replacement to prevent gear shifting hesitation. Oil change is routine, but don't forget to check if the spark plugs are eroded, affecting ignition efficiency. Replace the air filter if it's dirty to save fuel. Also inspect and clean the fuel filter to ensure smooth fuel flow. If the brake fluid has aged and absorbed too much moisture, replace it promptly to prevent brake failure. Check the belt tension, as a broken belt can cause major trouble. Test the lifespan of electrical components like the battery, which might be nearing its end. I always use simple tools to self-check the coolant level, which is easy and extends engine life. Maintain the air conditioning system for more comfortable use in summer.
The 70,000-kilometer maintenance involves many items, but I've simplified it to the essentials: Oil and filter replacement is fundamental. Check and replace spark plugs to prevent engine shaking. Measure brake pad thickness and replace if worn to ensure safety. Replace the air filter if dirty to improve air intake. Clean or replace the fuel filter to prevent clogging. Adjust tire pressure and check for wear. Verify the coolant's validity period and replace if expired. Conduct a comprehensive system scan to fix minor issues promptly. After reaching this mileage, my fuel consumption increased, but replacing certain parts improved it.
