FAQs
What vehicles is this tool set compatible with?
This set is designed for vehicles with serpentine belt systems. The included metric sizes cover many common domestic and import vehicles, but always verify your specific vehicle's tensioner size.
Can I use this tool for belt tensioner pulley bearing replacement?
While this tool is primarily for releasing and setting belt tension, some of the socket sizes may be compatible with certain pulley bolts used in bearing replacement, depending on the specific design.
What is the difference between the socket and crows foot sizes?
The sockets are designed to fit directly over the bolt head, while the crows foot adapters are designed to hook onto the specific designated points on the tensioner mechanism, often used to pivot the entire tensioner assembly.
Do I need both 3/8" and 1/2" drive ratchets?
The tool is compatible with both drive sizes. You can use whichever size ratchet you prefer or have available, as the kit includes adapters for both.
How do I know which size tool to use?
Refer to your vehicle's owner's manual or service manual for the specific size of the serpentine belt tensioner bolt or adjustment point. Visual inspection and trying the common sizes (13mm, 15mm) are also methods.
Is this tool suitable for DIY home mechanics?
Yes, this tool set is suitable for DIY mechanics who are comfortable performing basic automotive maintenance and have a basic understanding of serpentine belt systems and tensioners.
What are the specific socket sizes included?
The set includes 13mm, 15mm, 16mm, and 18mm socket sizes.
What are the specific crows foot sizes included?
The set includes 13mm, 14mm, and 15mm crows foot sizes.
Troubleshooting
Tool does not fit the tensioner bolt.
Verify you are using the correct size socket or crows foot. Consult your vehicle's service manual for the exact tensioner bolt size. Ensure the tool is seated fully onto the bolt head or pulley.
Ratchet slips on the crows foot adapter.
Ensure the drive size of your ratchet matches the drive connection on the crows foot adapter (3/8" or 1/2"). Check for any debris in the drive connection points. Use a quality ratchet with a strong engagement.
Difficulty releasing belt tension.
Ensure you are applying force to the correct pivot point or bolt on the tensioner as indicated by your vehicle's service manual. Use a longer breaker bar if necessary for increased leverage, but be mindful of the forces involved.
Tool shows signs of rust or corrosion.
Clean the affected area with a soft cloth and a mild lubricant. Ensure the tool is dried thoroughly and stored in a dry place. For minor surface rust, a brass brush can be used carefully.
