Just finished switching out the tensioner, idler pulley, and belt. You are correct, there is no cap covering the install bolt on the tensioner. The cap I ordered actually covers the wheel of the tensioner, which already comes with a cap when purchased new. Oh well, it was only a couple bucks so no biggie.
