Product Components

The complete OEMTOOLS 24687 Serpentine Belt Tool Set, including the handle, adapters, and sockets.

The extended handle provides superior leverage and torque for stubborn tensioners.
The OEMTOOLS 24687 Serpentine Belt Tool Set is a 7-piece kit designed for comprehensive serpentine belt maintenance. It includes:
- 3/8 inch Drive Steel Handle: The primary tool for applying leverage.
- 1/2 inch Drive Adapter: For use with 1/2 inch drive sockets or tensioners.
- 3/8 inch Drive Adapter: For use with 3/8 inch drive sockets or tensioners.
- 4 Shallow Sockets:
- 13 mm Socket
- 15 mm Socket
- 16 mm Socket
- 18 mm Socket

The set includes both 3/8 inch and 1/2 inch drive adapters for broad compatibility.

Four shallow sockets (13mm, 15mm, 16mm, 18mm) are provided for common applications.
Setup
Before using the tool set, ensure you have identified the correct size tensioner pulley bolt on your vehicle. Select the appropriate socket (13mm, 15mm, 16mm, or 18mm) and the corresponding drive adapter (3/8 inch or 1/2 inch).
- Identify the drive size required by your vehicle's tensioner pulley.
- Select either the 3/8 inch or 1/2 inch drive adapter.
- Insert the chosen adapter into the square drive opening on the end of the main handle. Ensure it is securely seated.
- Attach the correct size shallow socket to the adapter.
- The tool is now ready for use.

The handle's design allows for angle adjustments, improving reach in confined spaces.
Operating Instructions
This tool set is designed to provide the necessary leverage and clearance to release spring pressure from serpentine belt tensioners, facilitating belt removal and installation.
- With the appropriate socket and adapter attached to the handle, position the tool onto the tensioner pulley bolt. The slim profile of the tool allows access in tight engine compartments.
- Apply steady, controlled pressure to the handle to rotate the tensioner and release the belt tension. The extended handle provides ample leverage.
- Once tension is released, carefully remove the serpentine belt from the pulleys.
- For installation, route the new serpentine belt correctly around all pulleys, leaving the tensioner pulley as the last point.
- Re-apply pressure with the tool to the tensioner pulley bolt, rotating it to create slack, and then slip the new belt over the tensioner pulley.
- Slowly release the pressure on the tool, allowing the tensioner to return to its original position and apply tension to the new belt.
- Ensure the belt is properly seated on all pulleys before starting the engine.

The tool provides the necessary reach and leverage to work on serpentine belt tensioners in confined engine spaces.
Maintenance
Proper maintenance will ensure the longevity and performance of your OEMTOOLS Serpentine Belt Tool Set.
- Cleaning: After each use, wipe down all components with a clean, dry cloth to remove dirt, grease, and oil.
- Rust Prevention: The alloy steel construction with black oxide finish provides rust resistance. For prolonged storage or in humid environments, a light coat of rust-preventative oil can be applied to metal surfaces.
- Storage: Store the tool set in a dry place, away from moisture and corrosive materials. Keeping the components organized in their original packaging or a dedicated tool box will prevent loss and damage.
- Inspection: Periodically inspect the handle, adapters, and sockets for any signs of wear, bending, or damage. Do not use damaged tools.
Troubleshooting
If you encounter issues while using the OEMTOOLS 24687 Serpentine Belt Tool Set, consider the following common scenarios:
- Difficulty Accessing Tensioner:
Ensure you are using the correct combination of handle, adapter, and shallow socket. The tool's slim profile is designed for tight spaces, but some vehicle designs may still present challenges. Try adjusting the angle of the handle if applicable.
- Socket Slipping Off Bolt:
Verify that the correct size socket is being used and that it is fully seated on the tensioner bolt. Ensure the adapter is securely inserted into the handle. If the square drive connection between the handle and adapter feels loose, ensure it is fully engaged. Applying steady, direct pressure helps prevent slippage.
- Insufficient Leverage:
The extended handle is designed to provide significant leverage. If you are still struggling, ensure you have a stable stance and are applying force efficiently. Do not use cheater bars or extensions not designed for this tool, as this can damage the tool or cause injury.
