The owner wants to maintain his car. How to clean the throttle?

Remove the heat shield. Remove the air line around the throttle and record the position. The throttle valve is close to the combustion chamber, which is generally dirty and has black carbon deposition, and is the main cleaning part. The owner wants to maintain his car and throttle himself, about 20,000 times, 40,000 times and 60,000 times. Just read the maintenance manual anyway. But every time you go to a 4S store, you will be directly asked to repeat it over and over again. It only takes two or three hundred to improve power and reduce fuel consumption. Find the position of the throttle and the thickest hose in the engine, with one end connected to the square box and the other end connected to the engine. The throttle is where the engine is connected to the hose. You can see the hose when you take it off. In some cars, the throttle is under the hood, and you can see it when you take off the hood.

After finding the throttle valve, there are two cleaning methods, one is to remove it and the other is not to remove it. Turn on the throttle and clean it with a rag. If your throttle looks like a thin layer of grease in the video, you don't need to take it off and clean it, just wipe it with a cloth. Electrify the car before cleaning it, but don't ignite it. Push the throttle with something and the throttle will open. In this way, the throttle can be cleaned at the same time, the front and back sides of the throttle can be sprayed on the cloth, and the inside of the throttle can be cleaned. Cleaning agents can be bought online, and a bottle is not expensive.

Some friends can use carburetor cleaner or WD40 instead of throttle cleaner, absolutely not. Lubricate the throttle surface, carburetor cleaner or WD40 to remove grease. But it will destroy the coating, but it will make the throttle more likely to accumulate carbon and grease, which is not cost-effective. Then wipe it clean and clean the inside of the air filter box. If the air filter element becomes dirty, please replace it as soon as possible. You don't want to clean the bedroom and living room. If you don't care, it's like washing for nothing. If your accelerator has a thick layer of grease and carbon deposit, you'd better clean it up.

Unplug the wire harness next to the throttle and unscrew the four fixing screws at the top with T30 hexagon screwdriver. There is no T30 screwdriver, just a flat screwdriver of our size. After the throttle valve is completely removed, cover it with a clean towel and air inlet to prevent sundries from falling into the engine. After removing the throttle, you can see that the front is clean, but there is a thick layer of grease at the back. So at this time, I suggest my friends take it down and wash it. Then, spray the cleaning agent on the dirty place, because the throttle surface is a lubricating coating, and generally, direct spraying can completely remove the dirt.
