The 5VZ-FE engine requires a significant amount of force to break loose and retorque the crank bolt. After some light iterations, this tool successfully helped me break free the 19mm crank bolt on a 1997 Toyota 4Runner. The tool also doubles as a cam holder and blunt instrument (use with discretion). *This is mostly a joke. Buy it if you'd like to make a donation/contribution to the business and I'll ship this abomination to you. Features include: bent-holding bolts 19mm/17mm centralized socket access metal reinforcements for added strength sharp protruding points (dangerous) 'Patch' wood-burnt brand crack (very cool patina- lots of street cred) DISCLAIMER: the purchase of one (1) 'Cruiser Patch 5VZ-FE Crank Holding Tool' absolves Cruiser Patch L.C. of all liability, responsibilities, and/or damages. Purchaser assumes any and all consequences of use. Purchase at your own risk!
