How often should I clean the throttle when changing the oil?

4S shop maintenance notes 10 car maintenance tips.

1, common sense of oil change

No matter what kind of car, you should use synthetic engine oil, and the quality of this oil must be a regular brand. As long as it is made in synthetic engine oil, it is no problem to change the oil from 1.5 to 20,000 kilometers, only the oil and oil filter can be changed.

2, clean the engine tips

For the cleaning cycle of the throttle, it should be cleaned every 20,000 km to 30,000 km, because carbon deposition on the throttle is inevitable.

The main source of carbon deposition in throttle valve

It is the insufficiency of mixed combustion of air and fuel. Insufficient combustion will remain in the intake and throttle to form carbon deposits, which will cause engine idling jitter and increase fuel consumption over time.

3, replace the air filter tips

Basically, the oil was changed two or three times, and only one air filter was needed.

4. Tips for replacing gasoline filter

The replacement cycle of gasoline filter is longer. Only after replacing two or three air filters can the gasoline filter be replaced. Moreover, some gasoline filters are installed in the fuel tank, and the gasoline pump is integrated. If the oil pump is broken, just replace the gasoline filter.

5, change the gearbox oil circulation tips

As long as it is the original gearbox oil, when should the automatic gearbox oil be changed after at least 200,000 kilometers? AT is generally around 65438+ 10,000 kilometers, and CVT is changed at 80,000 kilometers.

Oil change mode

Changing gravity directly is the most practical. When changing the oil, remember to change the gearbox filter.

7, replace the spark plug tips

Ordinary spark plugs can be inspected and replaced about 50,000 kilometers. If they are platinum spark plugs, they can be inspected and replaced at 65,438+10,000 kilometers.

Judge whether the spark plug is replaced.

If the spark plug is badly ablated, there are scars, black lines, cracks and electrode melting at the top, which means that the spark plug has been damaged and must be replaced immediately.

8. Tips for replacing brake pads

Now a little higher-end cars are basically equipped with brake alarm lines, that is, they can run another three or five thousand kilometers after grinding to the alarm line, and this alarm line must be changed together.

9, replace the brake disc tips

Basically, if you change the brake pads two or three times, you should change the brake discs. There is no need to change the original brake discs. The original one is too expensive, just go to a regular repair shop to replace it.

10, tire replacement tips

Basically, change it once every 70,000-80,000 kilometers. Pay attention to the tire pressure. Too high tire pressure is easy to cause tire puncture, and too low tire pressure will lead to increased fuel consumption. Therefore, we should regularly check the tire pressure.
