How to Clean Throttle Body on a Turbocharged Car

Introduction

The throttle body is a crucial component of your car’s engine. It controls the amount of air that flows into the engine, which in turn affects the engine’s power and performance. Over time, the throttle body can become dirty and clogged with carbon deposits, which can lead to a variety of problems, including:

• Reduced engine power
• Rough idle
• Stalling
• Increased fuel consumption

If you’re experiencing any of these problems, it’s likely that your throttle body needs to be cleaned. Cleaning the throttle body is a relatively simple process that can be completed in about an hour. In this article, we’ll provide you with step-by-step instructions on how to clean the throttle body on a turbocharged car.

Tools and Materials

Before you begin, you’ll need to gather the following tools and materials:

• Throttle body cleaner
• Shop rags
• Screwdriver
• Wrench

Safety Precautions

Before you begin working on your car, it’s important to take the following safety precautions:

• Park your car on a level surface and engage the parking brake.
• Allow the engine to cool down completely before you begin working on it.
• Disconnect the negative battery terminal.
• Wear safety glasses and gloves to protect yourself from chemicals and debris.

Step-by-Step Instructions

Now that you have all of the necessary tools and materials, you can follow these step-by-step instructions to clean the throttle body on your turbocharged car:

1. Remove the air intake hose

The air intake hose is connected to the throttle body by a large rubber boot. To remove the air intake hose, simply loosen the hose clamp and pull the hose off of the throttle body.

2. Remove the throttle body

The throttle body is held in place by four bolts. To remove the throttle body, simply use a wrench to loosen the bolts and then carefully lift the throttle body off of the intake manifold.

3. Clean the throttle body

Once you have removed the throttle body, you can clean it using throttle body cleaner and shop rags. Be sure to clean all of the carbon deposits from the throttle body bore, the throttle plate, and the throttle position sensor.

4. Reinstall the throttle body

Once the throttle body is clean, you can reinstall it by reversing the steps that you used to remove it. Be sure to tighten the bolts securely, but do not overtighten them.

5. Reconnect the air intake hose

Once the throttle body is reinstalled, you can reconnect the air intake hose. Simply slide the hose back onto the throttle body and then tighten the hose clamp.

6. Reconnect the negative battery terminal

Once the air intake hose is reconnected, you can reconnect the negative battery terminal. Be sure to tighten the terminal securely.
