Does anyone know exactly what BMW/MINI specific tools should be used for this job? Is it a special crank puller and a belt tensioner tool? Any idea of the cost for these tools? Anybody already have these tools who is reasonably close to the Chattanooga, Tennessee area? I am concerned about attempting the job without the special tools - is this concern warranted? Having an Alta crank pulley sitting in its box and not on my car is killing me! I don't, however, want to go through an installation nightmare if the BMW/MINI tools can make the difference. Help please!!!
