No need, really... just make sure the 3-prong switch is working that triggers the fan at 105°C.

Sounds to me like it's fixed!

When engaged, you can tell from outside the car, but not usually inside... unless the metal fan is significantly louder. Perhaps that's one of the benefits of the plastic fan - reduced noise. (?)

It absolutely DOES make a difference at freeway speeds! Many people have the misconception that at freeway speeds, the "ram air" effect takes over and the fan isn't required. This is wrong, wrong, wrong... as you have just discovered. I learned the same thing myself back in 1998 when I was chasing down my temp issues, and a new clutch dropped freeway engine temps a solid 5-10°C with no other changes. When the change is this dramatic, the old clutch was likely totally dead, empty of silicone fluid, and just barely freewheeling. You can refill the old clutches, btw, if you really want to save some $$. I fixed two of 'em that way, but the process takes hours.
