The throttle sounds louder after washing the car.

It is normal that the noise of the car after cleaning the throttle is louder than the original noise, and the engine has an adaptation process. Maintenance method of automobile engine;

1, the use of good quality engine oil, engine oil, can play a role in lubrication, cleaning, cooling, sealing, reducing wear and so on. Only by using qualified lubricating oil can the wear of engine parts be reduced and the service life be prolonged. Therefore, we should pay attention to adding good quality engine oil, not shoddy, and don't let the engine run out of oil;

2. It is very important to use qualified coolant (antifreeze). The automobile engine needs to rely on the water tank to cool down, otherwise the engine will easily "boil" and cause fatal damage to the engine. Therefore, it is usually necessary to keep the coolant in the water tank at a normal level, and choose a good quality coolant, especially in winter, and choose a suitable coolant according to the ambient temperature. In the normal maintenance of automobiles, it is necessary to replace the engine antifreeze every year;

3. Regularly clean the water tank scale. The engine water tank is easy to rust and scale. Rust and scale will limit the flow of coolant in the cooling system, reduce heat dissipation, lead to overheating of the engine and even cause engine damage. Therefore, in daily maintenance, we should choose the appropriate coolant ratio according to the specific situation. And when adding coolant, it can be between the maximum value and the minimum value.
