I have a '05 bew 175000 mi and a '06 brm 83000 mi. timing belts need changed on both. i'm wondering which tools can be used on both? is there a tooling set that is adapted to both or do i need two seperate sets? where can i rent them? the '05 was done by the dealer at 100000. i work in deisel machinery for a living so i know that half the job is have the right tools. thanks for any help.
