How to Clean the Throttle Body of GAC Trumpchi GS4?
2 Answers
GAC Trumpchi GS4 throttle body cleaning steps are as follows: 1. Turn off the ignition switch and remove the negative terminal of the battery. 2. Remove the throttle cable, intake hose, and the screws fixing the throttle body. 3. Use carburetor cleaner to clean the throttle body, and use cotton thread to wipe areas that are hard to reach. 4. After cleaning, reinstall the throttle body in the reverse order of removal, and test whether the cleaned throttle body allows smooth air intake. Below is information about the throttle body: The throttle body is a controllable valve used to regulate air entering the engine. Above (or in front of) it is the air filter, and below it is the engine block. The position of the throttle body is equivalent to the "throat" of the car. After air enters the intake pipe, it passes through the throttle body and then mixes with gasoline to form a combustible mixture, which participates in combustion to do work. The stability of the car's idle speed and the flexibility of acceleration are closely related to the cleanliness of the throttle body.
Last time I cleaned the GS4 throttle body myself, I first disconnected the negative terminal of the battery to ensure safety. When removing the intake pipe, you'll encounter a clip—just pry it open with a flathead screwdriver to remove it. Here's the key point: the back of the throttle body is much dirtier than the front. Use a throttle body-specific cleaner and spray it onto a soft-bristle brush to clean it slowly. Never use carburetor cleaner as it can corrode the coating. Finally, don't rush to start the engine after reassembly. First, turn on the ignition without starting the engine and press the accelerator for 30 seconds to let the ECU learn the throttle opening. Otherwise, the cold start the next day might rev up to 2000 RPM. The whole process takes about an hour, and after cleaning, the throttle response becomes noticeably smoother.
