Hi Brad, Hello From Scotland
haha, now you're asking a bit of a question!!!
first of all , if your car is a 9000, it IS a painful job, but achievable with gritted teeth , a lot of swearing and a couple of hours to spare!!!
On working ****e, you will definitely need to remove the appropriate roadwheel and wheel arch trim and Liner (a few nuts and bolts)easy peasy...
this is essential to get enough room to do said job!!!
If you are replacing the belt, i recommend replacing the plastic idler pulley(s) while you are at it!(they are cheap and easy to replace, and are miserably weak!!!!!
(just bare in mind that you should only attempt all of this if you have a suitable workshop manual) Haynes make a semi decent manual, about £15, but much needed for reference.
You may also need a tool for holding the tensioner in place (you may have to make it!)
This is based on my '94 9000 turbo , which has a single drivebelt and tensioner , it may be easier for your car, i will look into it and post my findings....
If you don't have/can't get a manual, i can (try) to run you through it if i have the info....
