Again thanks for responses.
While I feel better about this situation than I did this morning, I have just been surprised by the door sill rust fairy...its not good

but that will be another thread.
The belt tensioner is dealt with in the 2004 Service Manual in section 7, page 45.
You need a 5mm (3/16") diameter locking pin, it shows the cast in hex head to use as a leverage spot. Others use another spot to lever on as the cast hex head tends to round over quickly, but maybe they are not using a metric wrench or socket.
