Review: Sale de buena calidad y para espacios reducidos es muy útil
Review: I was helping my dad change an alternator on a Dodge Grand Caravan, in which the belt tensioner is virtually inaccessible using regular tools. I don't do a ton of automotive work, but I am usually able to get to belt tensioners with normal tools. Anyway, with no other options, we purchased this item and it worked wonderfully. The old adage about having the right tool for the job definitely applied to this device! It has a thin bar, allowing you to get into tight places, and the additional bar for leverage makes it possible to release the tension with little effort. It also comes with multiple attachments to ensure it fits most any application. I highly recommend this product.
