Review on GearWrench 3680 Ratcheting Wrench Serpentine by Corey Singh

This is one of those tools you use once and it pays for itself. The alternative is to rent it from a parts store, clean it after you're done, return it and rent it again if you need to remove the belt for some reason. etc. etc. The tool is solid and well made. Stores neatly in a storage box. Multiple angles in addition to the ratchet make it "handleable" in many configurations around the engine bay. You will find that there is usually an o-ring around the 3/8 drive that is used for more than just holding wrenches. but also for 3/8 Direct Drive tensioners. MY SUGGESTION: Use a small pick to remove the o-ring and set it aside until you need to use it with a crow's foot. Using a 3/8 drive on the tensioner is much easier without this o-ring.
