How often does the Pentium B70 throttle need to be cleaned?

Pentium B70 accelerator is cleaned every 20,000-30,000 kilometers. If the throttle is not very dirty, you can clean it with cleaning agent without disassembling the throttle. But removing the throttle valve and cleaning it can make it cleaner. The cleaning steps for removing the throttle valve are as follows:

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

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. Use special throttle cleaner or carburetor cleaner, spray some on the throttle until the carbon deposit is completely dissolved by organic solvent, and wipe the stain after 1-2 minutes.

In addition to the above methods, there is also a cleaning method without removing the throttle. As long as the engine is running, cleaning agent can be sprayed into the accelerator. The practice of most 4S shops and after-sales service centers is to spray cleaning agent on the accelerator while stepping on it. At this time, the car will emit white smoke because the cleaned stains are 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 harmful and beneficial to the car.
