Pros

•Provides enormous leverage on serpentine belt tensioners, making belt removal and installation much easier.
•Functions well as an extrong ratchet, offering better access and leverage in tight spaces.
•Durable and strong enough to be used as a breaker bar for heavier tasks without concern for breaking.
•Higuality construction with quality castings and a polished finish, enhancing reliability.
•Versatile and includes a 3/8 inch drive socket allowing use with your own deep 19mm sockets for tricky bolts.
•Significantly improves ease of use and efficiency on belt work compared to traditional ratchets or competing brands like Icon.
•Recommended by many users for automotive maintenance, especially on vehicles like the 2016 F250 and 2013 GMC Sierra.
•Reliable and straightforward to use, building confidence during repairs or installations.
•Works well for haro-reach tensioners, including unconventional access points such as from underneath wheel wells.

Cons

•Does not have a fleead, making it difficult to maneuver at tight angles or in confined spaces.
•May not be more convenient than a standard ratchet for some vehicles (e.g., 2017 Honda Pilot).
•Requires using your own deeper 19mm socket for certain models like the 2007 Toyota RAV4 as the included socket may be too shallow.
•The tool is optimized for serpentine belt tensioners but might not hold up as well on heavieuty wrenching jobs beyond that scope.
•For some vehicles, a long 19mm fleead wrench could offer better maneuverability and ease of use compared to this model.

Bottom Line

The GearWrench 3680 Ratcheting Wrench Serpentine Belt Tool is a well-made, highly effective solution for anyone tackling serpentine belt work, especially when extra leverage and reach are needed. While it shines for belt tensioners and can double as a breaker bar, its lack of a flex-head limits versatility in tight or angled spots. If you frequently work on vehicles with limited clearance or need better maneuverability, you might consider pairing this with or opting for a long 19mm flex-head wrench. Overall, this tool delivers great value and performance for its intended purpose in automotive maintenance.
