[Spits] fan clutch

[Larry Vaughan]

I bought a new water pump for my Spitfire. It's a mongrel but I went 
with the 1977 large upright radiator and the clutch type fan. Before I 
mounted the clutch on the new water pump, I heated it up with a hair 
dryer to see how much the resistance changed. When it was too hot to 
handle bare handed, with mitts, I could turn the center part as easily 
as when it was cold? There is a fair amount of resistance cold but it 
should increase with heat right? How much heat? To the point of lock up?
