Essential Maintenance Checklist for Your Newly Purchased Used Car

As a newly purchased second-hand car, some necessary maintenance measures are required to ensure the normal operation and service life of the vehicle. The following are some necessary maintenance items:

 

Check and maintain spark plugs:

The service life of spark plugs is 15,000 kilometers, and the service life of long-lasting spark plugs does not exceed 50,000 kilometers. When the car travels to a certain number of kilometers, the spark plug will produce carbon deposits and the electrode gap will increase. The carbon deposit will increase the engine's fuel consumption, and the increase in the spark plug gap will cause difficulty in starting.

Replace engine oil and oil filter:

The oil compartment, gasoline compartment, air compartment and air conditioning compartment are commonly known as the "four compartments" of a car. Although they are inconspicuous, they play a huge role. The function of the oil grid and gasoline grid is to filter out impurities in the oil and gasoline so that the engine can run normally.

Replace belt and water pump:

If you are buying a vehicle that is more than 5 years old or has a mileage of more than 80,000 kilometers, the safest solution is to replace it with a new engine timing belt. You can also replace the water pump and belt at the same time. If you wait until the water pump Damage or aging and breakage of the belt can be very dangerous.

Pay attention to cleaning the air conditioner:

Car air conditioner evaporators, fans, etc. have been in a closed and dark state for a long time, and the internal environment is high and humid. After impurities, dust, bacteria, and viruses in the air enter the interior of the air conditioner, they stick to the condensed water and block the evaporator and other components, adhering to a large amount of dirt, nicotine, mold, etc. Fungi will multiply quickly and produce putrid odors. These odors will be mixed with the air-conditioning as the air conditioner is turned on, contaminating the entire interior of the car and often making drivers and passengers feel uncomfortable.

Change gearbox oil:

Gearbox oil is an oil that keeps the gear system clean. It is most easily overlooked. After buying a second-hand car, you should replace it with gearbox oil that meets the manufacturer's specifications. This is especially important for cars that are more than 5 years old.

Maintain the battery:

Check the date of the battery or the status of the display. If you find that the sound becomes muted or the lights dim when you start the engine, it is a sign that the battery is exhausted and it is best to replace it as soon as possible.

The above are some maintenance measures that need to be carried out after buying a second-hand car. The implementation of these maintenance projects can not only extend the service life of the vehicle, but also ensure the normal operation and driving experience of the vehicle. Therefore, as a car owner, you should perform these maintenance tasks regularly to ensure the safety and reliability of your vehicle.
