What kind of throttle can't be washed off? What should I pay attention to when cleaning the throttle?

The electronically controlled throttle cannot be removed for washing, and everything else can be removed for washing.

Precautions for cleaning the throttle are as follows:

If you want to know the cleaning problem of the throttle, let's first look at the most important function of the throttle. The most important function of throttle valve is to control air to enter the engine. The depth of our step on the accelerator is directly related to the opening of the accelerator.

It can be said that the throttle valve is the "mouthpiece" for the normal operation of the whole automobile engine. Generally, 4S shops recommend driving to about 20,000 kilometers to clean cars. Of course, the mileage is not very fixed, depending on the model, and some models are even eight or nine thousand kilometers.

When the idle speed of our car is unstable, it may mean that the throttle of our car needs cleaning. Some cars will also have external manifestations such as starting difficulties and even power decline. Therefore, it is necessary to clean the throttle.

There are also many precautions when cleaning. First of all, the cleaning agents we buy are generally very corrosive, and it is easy to cause excessive corrosion of aprons or oil seals during cleaning, resulting in unstable idle speed.

In addition, many 4S always advise car owners to clean the throttle, but excessive cleaning of the throttle will lead to premature scrapping of the throttle, and the throttle will not be broken because of dirt, and the teacher will die because of frequent cleaning.

The main reason is that frequent cleaning leads to the special coating of the throttle cavity being "scraped off" layer by layer, and the inner cavity loses its coating, which is more likely to cause greasy adhesion, thus starting a vicious circle until it is scrapped.
