Tool rental is also available from Detroit Tuned. 1 Review 5 85 Bucks, or 85 Headaches Posted by Brendan in Denver on 13th Jul 2015 Some people say you can remove the tension from your Mini serpentine belt without this tool. Don't even bother trying. With this tool the removal time is about 45 seconds; installation is even less. Without it you would be better off pounding nails into the floor with your forehead. If you are a decent human being who lives in the Denver are and want to borrow mine, look me up.
