How often is the throttle valve cleaned?

Clean the throttle every 20-30 thousand kilometers. If it is not too dirty, you can use the method of not removing the throttle. The cleaning agent can directly clean the throttle valve. But it can be cleaned more cleanly by removing the throttle valve. The cleaning steps for removing the throttle valve are as follows:

1. Find the throttle position and connect it directly to the air filter behind the air inlet;

2. Remove the hose connecting the throttle valve and the air cleaner first, and then remove the air cleaner assembly;

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

4. Spray carburetor cleaner or special cleaner on the throttle valve, wait for the carbon deposit to be dissolved by organic solvent, and dry it after 1-2 minutes.

Not only that, there is also a cleaning method without removing the throttle. When the engine is running, the cleaning agent is directly injected into the throttle. The practice of most 4S shops and after-sales service centers is to blow accelerators and cleaning agents into them. At this time, the vehicle will emit white smoke because the cleaned stains are strongly ignited by the suction cylinder and then discharged. This cleaning method is still harmful to the car. It is suggested that it is best to disassemble the car and clean it, which will cause less damage to the car.
