How to Clean a Throttle Body & Which Cleaner To Use?

In Engine by Magnus SellénLeave a Comment

The throttle body is an extremely important part of the car, which plays a key role in the proper functioning of a vehicle.

It controls the amount of air that is admitted to the ignition chamber. The path of the air is blocked by a small circle that turns slightly or completely, depending on how hard you press the pedal. The throttle body must therefore be in top condition. If it is slightly impaired, your car may not run properly in neutral.

Fortunately, there are ways to solve this problem without spending a lot of money. We are here to help you by showing you how best to clean the throttle bodies.

Throttle Body Cleaning Process

Only the basic tools are required for this do-it-yourself work. Such tools could be available in your home if you enjoy doing regular DIY work, if not, you should make a few purchases before you start the actual work:

  1. A 4-in-1 screwdriver
  2. Nut driver

Other Materials

You need some necessary materials to carry out this exercise. These materials can easily be found at a home store.

  1. Paper towel
  2. Spray can
  3. Throttle body cleaner

The throttle body cleaner is the only material that is absolutely necessary for the proper cleaning of the throttle body. There are many cleaners on the market, but it is absolutely necessary to get the best one, otherwise your engine could be at risk.

We will talk about the best throttle body cleaner later in this article. Let’s concentrate on the cleaning process for now.

1. Remove the air duct

Separating the air duct from the throttle body is the first step you should take. The air duct basically looks like a hose, so it should not be difficult to locate it. It is usually connected to the business end of the throttle body: the part where it breathes air.

Unscrew the air duct from the throttle body and mark all the openings and electrical connections that could go through the air duct.

2. Spray throttle cleaner

The next step is to spray the throttle cleaner into the opening. Note that the opening of the throttle body is protected by a butterfly. To open the throttle body, locate the throttle cable and pull on it. Once the throttle is open, you must place the throttle cleaner in the opening and spray vigorously. Make sure that the cleaner is not wasted.

3. Spray air into throttle body

The third part is the most difficult and complex. First, you’d have to get an air compressor. When you’re done, you’d have to hold your hand steady and spray air into the throttle body. The compressed air dries the throttle cleaning fluid and prevents it from trapping dust.

4. Clean the throttle body

Finally, you must clean the outermost part of the throttle valve with a paper towel or cloth and then reattach the air duct in place. Ensure that you place all relevant electrical wires and equipment in their proper locations and that you seal the air duct tightly. A throttle valve cannot function properly if the air duct is not properly sealed.

And that’s it! You have cleaned the throttle body of your vehicle. However, one question remains unanswered. What is the best throttle body cleaner on the market? Let’s find out. Shall we do that?
