Do major car maintenance? None of these items can be missed

We know that car maintenance is divided into small maintenance and major maintenance. The car has reached the node of 60,000 kilometers, and we need to do a thorough maintenance. If the maintenance is done well this time, the chances of problems with this car will be much less in the future. Now let’s take a look at the necessary maintenance items for 60,000 kilometers.

1. Oil + oil filter

Oil is the lubricating oil for engine operation. It can play a role in lubricating, cleaning, cooling, sealing, and reducing abrasion of the engine. It is of great significance to reduce the wear of engine parts and extend the service life.

2. Air filter

The role of the air filter is to provide cleanliness for these engines Air, to prevent the engine from inhaling air with impurity particles during work and increase the chance of abrasion and damage.

3.

Timing belt

About timing belt, I think Most of them are a little unfamiliar with it. The reason why it is put at the top is because of its importance. Generally, a car needs a major maintenance when it is 60,000-80,000 kilometers, and the timing belt is the one that must be checked. project.

Why?

Because the timing belt is a consumable product, and once the timing belt is broken, the camshaft will not run in accordance with the timing. At this time, it is very likely that the valve and the piston will collide and cause serious damage, so The timing belt must be replaced according to the mileage or time specified by the original manufacturer.

For details, please refer to the manual given by your 4s shop. Whether your car is a maintenance-free timing chain or a timing belt. The general timing belt requires 60,000 to 100,000 kilometers to be replaced. Many timing chains are also maintenance-free. If the timing belt inspection is no problem, it will continue to be used for two years. Generally, it must be replaced for 80,000 kilometers.

4. Gasoline filter

Gasoline is not pure, there are many impurities in it, and Impurities can also enter when the fuel tank cover is opened during refueling or maintenance. These relatively small impurities are likely to damage the oil pump. In addition, the fuel injector is a high-precision and easy-to-clog object. If it is blocked, it will increase fuel consumption, unstable idling speed, and decrease power.

5. Spark plugs

Spark plugs are used in the ignition equipment of gasoline engines, one for each cylinder, which is worth mentioning The point is that the spark plug does not only ignite once, but as long as the engine is working, it will always be in the ignition state according to the engine's four-stroke principle (intake, compression, ignition, exhaust).

Once the spark plug is not working properly, it will be 'lack of cylinder' phenomenon. Listen carefully, and the sound will suddenly 'burst' again. Look at the exhaust tube. There is black smoke. It has many materials. According to the material Different replacement time is different.

Nickel spark plug: 30,000 kilometers

Platinum spark plug: 50,000 kilometers

Iridium spark plug: 100,000 kilometers

6. Antifreeze

If the antifreeze is not replaced in time, the performance will decline. First, the antifreeze ability will decrease, the freezing point will rise, and the cold place will easily freeze , The water tank, water pipe, and even the engine will be damaged by freezing; secondly, the anti-rust and anti-corrosion ability will be reduced, and a large amount of scale and rust will be generated in the water channel, which will block the water channel and reduce the heat dissipation capacity.

7. Brake fluid

Brake fluid (brake fluid) has strong water absorption, Will automatically absorb moisture in the air. The high water content of the brake fluid will cause the boiling point of the brake fluid to decrease, and it is easy to produce bubbles, which will cause the brake to fail. In addition, if the brake fluid is used for a long time, it will produce a lot of impurities, the color will slowly turn black, the braking performance will also decrease, and in severe cases, the braking system will be damaged.

8. Gearbox oil

The gearbox and engine oil are different, and many people may be unfamiliar. The most frequently heard may be manual gearboxes and automatic gearboxes. The gearbox is composed of precision gears. The function of the gearbox oil is to lubricate these parts. Depending on the gearbox, the time for changing the gearbox oil is different.

Manual transmission oil: Replace it in 5 years or 100,000 kilometers.

Automatic gearbox oil: 3 years or 60,000 kilometers to replace.

9. Tires

Rubber products have a service life, and tires are the same. The use of general tires The age limit is 5-6 years, which can be judged by looking at the production date of the tire. After a long time, even if you drive carefully, the surface will harden and cracks will occur. Such tires should be replaced.

10. Battery

Under normal circumstances, the recommended replacement period for a maintenance-free battery is 3-5 years about. The actual service life of a car battery is closely related to the battery quality, ambient temperature, vehicle conditions, road conditions, and driver's habits. Proper use can extend the service life of the battery.

11. Brake pads

Because the replacement cycle of brake pads and the driving habits and road conditions of the car owner Great relationship. Usually the brake pads are replaced at 60000 kilometers or the brake alarm prompts to be replaced. The brake system must be checked every time for maintenance to see if the wear condition is close to the alarm line on the side of the brake pads. If it is close, it must be replaced in time.

12. Throttle cleaning

The main cause of throttle fouling is engine oil vapor, followed by air Particles and moisture in. The crankcase in front of the throttle valve is forced to ventilate. The crankcase ventilation will re-introduce the exhaust gas in the crankcase into the cylinder through the intake valve for combustion, which directly causes the throttle to become dirty.

The use and installation of performance camshaft is compared with most other systems for managing the best camshaft manufacturer effectively and no doubt performance camshaft have won the race so many times.
