Setup
- Select Appropriate Socket: Identify the correct size socket required for your vehicle's serpentine belt tensioner pulley bolt. The kit includes various low-profile sockets, including a 19mm socket for Honda and Toyota applications.
- Attach Socket: Securely attach the selected socket to the ratcheting head of the tool handle.
- Use Extension (if needed): For hard-to-reach idler pulleys, attach the extension bar between the ratcheting handle and the socket.
Operating Instructions
This tool is designed to release tension on serpentine belts with a spring-loaded idler pulley.
- Position the Tool: Place the assembled tool onto the serpentine belt tensioner pulley bolt. Ensure the socket is fully engaged with the bolt head.
- Set Ratcheting Head: Set the ratcheting head to the middle or neutral/freewheel position. This allows for initial positioning without engaging the ratchet mechanism.
- Apply Leverage: Apply steady pressure to the tool handle to rotate the tensioner pulley and release tension from the serpentine belt. The freewheel position allows maximum leverage.
- Lock Ratchet (if needed): Once the maximum travel point is reached, click the lever into place to lock the ratchet mechanism, holding the tensioner in the released position. This can be useful for maintaining tension release while manipulating the belt.
- Remove/Install Belt: Carefully remove the old serpentine belt or install the new one.
- Release Tensioner: Once the belt is in place, release the ratchet mechanism and slowly allow the tensioner to return to its original position.
- Verify Belt Routing: Double-check that the new belt is correctly routed around all pulleys according to your vehicle's specifications.

Troubleshooting
Issue: Tool does not fit tensioner bolt.
Solution: Ensure you are using the correct size socket for your vehicle's tensioner. The kit includes various sizes; consult your vehicle's service manual for the exact specification.
Issue: Difficulty reaching the tensioner.
Solution: Utilize the included extension bar to gain additional reach and leverage in confined engine compartments.
