You don't not loosen the water pump. You do that and you'll have coolant dumping all over you and the side of your motor. I don't know how the belt is on a Spyder but I do know you don't loosen the water pump. If its like the 4g63. I know you have a 4g64 the tensioner for the power steering is the actual power steering pump itself. You can pivot it back and fourth. Maybe they were talking about loosening the bolts on the pulley that attaches to the water pump but you don't need to do that.
