Have a thought.
Get a helper and a piece of string.
On the tensioner it should have 2 lines on one side and one on the other.
With the belt on, the tensioner will line the single line between the two. (good tensioner)
Have someone hold the tensioner in the proper range (perferabley middle) use the string to measure.

Sure your not looking at CA emissions with an air pump as opposed to a non air pump?
