How often should Peugeot 508 throttle be cleaned?

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

1. First find the throttle 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. Use special throttle cleaner or carburetor cleaner, spray some cleaner 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 disassembling the throttle, that is, when the engine is running, the cleaning agent is directly sprayed into the throttle. The practice of many 4S shops and after-sales service centers is to blow the throttle while spraying cleaning agent into the throttle. At this time, white smoke will appear in the car, mainly because the cleaned dirt is strongly ignited by the suction cylinder and discharged. This kind of cleaning method is relatively more harmful to the car. Generally, it is better to disassemble and clean, which is more beneficial to the car.
