How to clean the throttle of Subaru Forester?

1. First of all, if there is a plastic heat shield on the engine, it needs to be removed first.

When the hood is removed, we can usually see the throttle. There are some air pipes around the throttle, which need to be removed, and the position of each pipe should be clearly recorded.

3. After removing the air pipe on the throttle, we can remove the whole throttle. Trent's throttle is fixed on the engine block by four bolts, which can be quickly disassembled with suitable tools.

4. The side of the throttle near the combustion chamber is generally dirty, and the black carbon deposit marks are the main parts that need to be cleaned.

5. Cleaning the throttle is mainly to remove carbon deposits on it, and special throttle cleaning liquid or cleaner can be used. It should be noted here that the cleaning principle of this cleaning agent is to dissolve carbon deposit, and its composition is harmful to human body. It is best to wear gloves and masks when cleaning.

6. Spray the cleaner to the position with more carbon deposits on the throttle, and wait for about 5- 10 minutes to dissolve the carbon deposits. Using brushes can speed up the removal of carbon deposits.

7. When we see that the stain on the accelerator has completely dissolved, we can wipe the detergent inside the accelerator with a clean towel.

8. Install the cleaned throttle valve on the engine block according to the original position? Then install all the air pipes to complete the whole process of cleaning the throttle. After all the hardware is installed, we need to initialize throttle.
