How often is the throttle valve cleaned?

The throttle of Yue X is cleaned every 20,000-30,000 kilometers. If the throttle is not particularly dirty, you can directly clean the throttle with cleaning agent without removing the throttle. But it's better to remove the throttle and clean it. The cleaning steps for removing the throttle valve are as follows:

1. Find the position of the throttle, which is behind the air inlet and connected to the air filter;

2. First remove the connecting hose between the throttle valve and the air cleaner, and then remove the air cleaner assembly;

3. Then remove the throttle cable and unscrew the fixing bolt to remove the throttle;

4. Use special cleaning agent or carburetor cleaning agent, spray some cleaning agent on the throttle, wait for the organic solvent to dissolve the carbon deposit, and dry it for 1-2 minutes.

In addition, there is a cleaning method without removing the throttle. As long as the engine is running, the cleaning agent can be directly injected into the throttle. The practice of most 4S shops and after-sales service centers is to blow the throttle while spraying cleaning agent into the throttle. At this time, it will be found that the vehicle emits white smoke, mainly because the cleaned dirt is strongly ignited by the suction cylinder and then discharged. This cleaning method is very harmful to the car, so the disassembly cleaning method is more beneficial and healthier for the car.
