DNA MOTORING Serpentine Belt Tool Set 9pc — Belt Tensioner Wrench Kit with 2 Drive Bars & Molded Case

DNA MOTORING's 9-piece serpentine belt tool set is a purpose-built kit for releasing and routing belts on vehicles with spring-loaded automatic belt tensioners.

This compact, vehicle-focused toolkit assembles the bars, sockets and crowfoot wrenches most commonly required when servicing serpentine belt systems in tight engine bays. The set includes two drive bars sized for specific domestic engine families, four sockets and three crowfoot adapters, all organized in a molded storage case so you can work faster and keep everything protected between jobs.

Which vehicles and tensioner types will this kit work on?

The kit is engineered specifically for automatic, spring-loaded belt tensioners — not manual or hydraulic tensioners. It covers many domestic applications: the 9" 1/2" square-drive bar fits selected Chrysler (2.5L, 3.0L) and Ford (4.6L) engines, while the 23" 3/8" square-drive bar reaches into engine families such as Ford 1.9L, 2.3L and GM 3.1L.

• For spring-loaded automatic tensioners only — confirm your vehicle's tensioner type first.
• 9" bar (1/2" square drive) — Chrysler 2.5L/3.0L, Ford 4.6L compatibility.
• 23" bar (3/8" square drive) — Ford 1.9L/2.3L and GM 3.1L coverage.
• Covers a broad range of common domestic engines; verify fitment for uncommon models.

How does the set make belt removal and installation easier?

The long and short drive bars provide leverage in cramped engine compartments, while the crowfoot wrenches and sockets adapt to awkwardly placed fasteners without requiring full-size ratchets. The molded case keeps each piece visible and ready, reducing time spent searching for the right adapter during a repair.

• Two length bars give reach and leverage where a standard breaker bar won’t fit.
• Crowfoot adapters allow access to bolts at difficult angles.
• Molded storage case speeds tool selection and protects components.
• Compact kit reduces the need to carry larger, heavier tools into the engine bay.

What exactly is included in the kit and what materials are used?

The set contains four sockets, three crowfoot wrenches, a 9" 1/2" square-drive bar and a 23" 3/8" square-drive bar, all arranged in an injection-molded storage box. Components are manufactured to withstand typical shop use and are sized for the vehicle families noted in the product details.

• 4 sockets and 3 crowfoot wrenches for adaptable fastening options.
• 9" bar (1/2" square drive) and 23" bar (3/8" square drive) for reach and torque.
• Durable injection-molded case with individual slots and size markings.
• Complete twelve-piece layout (tooling plus case) for belt service jobs.

Who is this for: The DNA MOTORING 9-piece serpentine belt tool set is aimed at professional mechanics, automotive technicians and experienced DIYers who regularly service domestic engines with spring-loaded automatic belt tensioners. It’s most useful when space is limited under the hood and when you need reliable leverage and specialty adapters without hauling a full toolbox. Always check your vehicle’s tensioner type and engine compatibility before purchasing to ensure safe, correct use.
