Ok, this is what I have, hope it helps save seomone a few headaches. This is on a 97 SSEi, other years may very.
Jack up the right side, remove right wheel and plastic cover inside wheel well. Use jack stands!
Not sure if you will need to use a jack on the engin because you will not remove the motor mount, but just to be safe, put a 2x4 on teh oil pan and lift gently
Using a torex socket, turn tensioner counterclockwise and remove belt.
Go under car and remove bolt from lower motor mount where it connects to engine.
Then with a torex socket remove the stud that you just removed the nut from. If you don't have a torex socket, use a 5/16 6 point socket.
View from wheel well
You might have to loosen the upper bolt.
There is a spacer between the motor mount assembly and the engine, it will take a bit of effort to work this out, some wires are in the way but it will come out.
Here is the stud and spacer.
The belt should now come out. I only replaced one belt, but it looks like both will come out this way.
Put new belt in car, replace spacer and stud. Tighten everything you loosened, put belt back on all pullies and tensioners, your done.
If there are any errors in this, please let me know and I will make corrections.
