Thanks for the confirmation. The 12mm center bolt is a press fit and no way you can remove the tensioner without removing the water pump pulley. When you remove the pulley, you need to drain the radiator and remove the radiator. The list goes on and on. I then butchered up the 4 6mm allen bolts that held the wp pulley in place. It was a ROYAL PAIN in the A$$. Whoever designed it should be held accountable.
