MERCEDES 280SL PARTS

Installing a throttle body housing (0001406953) in a Mercedes 280 SL is a task that requires precision and careful attention to detail. All Mercedes 280SL parts require such attention. The throttle body housing is a crucial component in the vehicle’s intake system, controlling the amount of air that enters the engine. This guide will walk you through the process, ensuring your Mercedes 280 SL runs smoothly and efficiently. 

Tools and Materials Needed 

• New or used throttle body housing (0001406953)
• Screwdrivers (flathead and Phillips) 
• Wrenches and socket set 
• Torque wrench
• Throttle body gasket 
• Cleaning solvent and a clean cloth 
• Gloves and safety glasses 

Step 1: Preparing the Vehicle (applies to installing all Mercedes 280SL parts)

1. Safety First: Ensure the vehicle is parked on a flat surface. Engage the parking brake and disconnect the negative terminal of the battery to prevent any electrical issues. This step should be taken for installation of all Mercedes 280SL parts.
2. Locate the Throttle Body: Open the hood and locate the throttle body housing. It is typically connected to the intake manifold and air intake system. 

Step 2: Removing the Old Throttle Body Housing 

1. Detach the Air Intake Hose: Loosen the clamps securing the air intake hose to the throttle body. Carefully disconnect the hose and set it aside. 
2. Disconnect Electrical Connectors: Identify and disconnect the electrical connectors attached to the throttle body. These connectors control the throttle position sensor and other electronic components. When replacing all Mercedes 280SL parts that are electrical in nature, this step must be followed.
3. Remove the Throttle Linkage: Depending on the model year, the throttle body might be connected to a mechanical linkage. Carefully detach the linkage, noting its position for reinstallation. 
4. Unscrew the Throttle Body: Use the appropriate socket to remove the bolts securing the throttle body to the intake manifold. Keep these bolts as you will need them to install the new throttle body. 

Step 3: Cleaning the Mounting Surface 

1. Remove the Old Gasket: Once the old throttle body is removed, scrape off the old gasket material from the mounting surface on the intake manifold. Be careful not to damage the surface. 
2. Clean the Surface: Use a cleaning solvent and a clean cloth to ensure the surface is free of debris and old gasket material. A clean surface is crucial for a proper seal. 

Step 4: Installing the New Throttle Body Housing 

1. Install the New Gasket: Place the new throttle body gasket onto the cleaned mounting surface. Ensure it aligns correctly with the bolt holes. 
2. Position the New Throttle Body: Carefully position the new throttle body housing (0001406953) onto the intake manifold, aligning it with the bolt holes and gasket. 
3. Secure the Throttle Body: Insert and hand-tighten the bolts that secure the throttle body to the intake manifold. Once all bolts are in place, use a torque wrench to tighten them to the manufacturer’s specifications. Over-tightening can damage the gasket or the throttle body housing. 

Step 5: Reconnecting Components 

1. Reconnect the Throttle Linkage: If your vehicle has a mechanical linkage, reattach it to the new throttle body, ensuring it moves smoothly. 
2. Reconnect Electrical Connectors: Reattach all electrical connectors to the throttle body. Ensure each connector clicks into place securely. 
3. Reattach the Air Intake Hose: Reconnect the air intake hose to the throttle body and tighten the clamps securely. Ensure there are no air leaks in the system. 

Step 6: Final Checks 

1. Reconnect the Battery: Reconnect the negative terminal of the battery. 
2. Inspect Your Work: Double-check all connections, bolts, and clamps to ensure everything is secure and properly installed. This step should be taken no matter what Mercedes 280SL parts.
3. Start the Engine: Start the engine and let it idle. Listen for any unusual noises and check for any signs of air leaks around the throttle body. 
4. Test Drive: Take the vehicle for a short test drive to ensure it operates smoothly. Pay attention to the throttle response and overall performance.

 Tips and Warnings (applies to installing all Mercedes 280SL parts)

• Consult the Manual: Always refer to the vehicle’s service manual for specific instructions and torque specifications. 
• Work in a Clean Environment: Keep your work area clean to avoid contaminating the throttle body and intake system. 
• Handle with Care: The throttle body is a precision component. Handle it carefully to avoid damage to the electronic components and sensors.
