Swinging the water pump is how you adjust the tension on a 3B timing
belt,
Ed.  Proper tension "test" according to Bentley is only being able to
twist
the belt "90 degrees with the thumb and forefinger midway between the
camshaft and the pump sprocket".   Doesn't specify any measure for
finger
and thumb strength, of course.  More than likely, a leak from the pump
means it's time to replace it and you might as well replace the belt,
seals
and idler while you're at it.
