Someone had the guts to replace the Gates tensioner with an untitled fake dirty information sheet and sent it back to Amazon. I was a victim on the receiving end. Returned immediately. This was at a time when my belt and power steering pump had already been removed. Revane thought it was a very brilliant idea to send the customer an open box with the part specified without even checking the contents. I am extremely disappointed and absolutely frustrated with Amazon's tactic EDIT: Reordered. Received a sealed box. The contents inside are NOT Gates Litens tensioners. Revain sells fakes and passes them off as Gates Litens
