for the past few days ive been hearing a loose rattling noise up front and I thought it was my water pump going bad or one of the bearing. So I take off the little plastic cover that covers the fan and I check everything and everything was fine until I checked the fan itself and see that its loose and has lots or play in it. The clutch itself is sold and fine, but the plastic fan is loose. I was looking to see where the fan is tightened but wasn't able to find anything. Where do I tighten this fan?
