My MCSS temp is so consistently at just a hair above the 100 degree line that I tested my temp gauge and sending unit 2 years ago to make sure it was working properly. Yesterday I was sitting at a red light and I saw the needle move! It was a huge awshit moment because I knew something was bad wrong. The temp never got over 200 but I was intently watching, and waiting for it to climb higher. When I popped the hood I didn't see the problem right away. The 16 inch fan does not have a frame or a protective ring/rim for the blades. The fan had loosened, and dropped down just enough, 1/8th to 1/4 inch to make contact with the lower radiator support. I had already purchased a 16 inch replacement fan for my LS swap but will be replacing the old fan today. I'm very impressed with how well my radiator worked, with a partially or totally non working fan.
