Simple AAR test.  Remove from vehicle.  Put in freezer along with frozen
food for an hour or so.  Take it out and look through it.  Passage should be
wide open.  Go to your electric stove and put an element on lowest setting.
Put AAR on element using same surface that goes against engine.  When it
warms up, passage will be closed.
