TLDR Review: GearWrench Serpentine Belt Tool
Verdict
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.
- Top pro:
- Provides enormous leverage on serpentine belt tensioners, making belt removal and installation much easier.
- Top con:
- Does not have a flex-head, making it difficult to maneuver at tight angles or in confined spaces.
Pros
- •Provides enormous leverage on serpentine belt tensioners, making belt removal and installation much easier.
- •Functions well as an extra-long 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.
- •High-quality 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 hard-to-reach tensioners, including unconventional access points such as from underneath wheel wells.
Cons
- •Does not have a flex-head, 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 heavier-duty wrenching jobs beyond that scope.
- •For some vehicles, a long 19mm flex-head wrench could offer better maneuverability and ease of use compared to this model.
