coolant leak to timing belt job?

My pursuit of a coolant leak in the Avant has uncovered a seriously loose
timing belt. I had thought the leak was suspiciously coming from an area
that could certainly have been from the w/p. None of the many small hoses,
buried by the now removed p/s pump seem to have been leaking. Is it true
that the timing belt tension is provided by adjusting the water pump? I
know that's how it is on the AAN but haven't played the t-belt game on a 3B
or any 10v motor before. My theory is that the water pump adjustment came
loose and the water leak is a symptom of that. Boy am I glad I parked it
and got the V8 t-belt done and out of the garage before digging into this.
The belt is so loose that I can wiggle it back and forth on the water pump
pulley. I could pop it off with one finger if I wanted to. I can bend the
belt 90 degrees with one finger. The opposite length of it between the cam
pulley and crank pulley is snug, but also easily turned 90 degrees.
I've got the Bentley out and will be reading up on timing belt tensioning
tonight in bed. Ooh baby.
