<VV> Alternate Fans?

[Matt Nall]

Wouldn't a clutch fan work better ?
It would only catch when the fan speed is less than the belt speed and 
would free wheel on deceleration...

Just a thought

 Rodney....  common "clutch fans" do not work that way....  three common types


1  Cheap...centrifugal...  clutch releases at higher  rpm...  as when car is going 20 mph  or more....  not good for trucks / large cars....  they will allow overheating on hills.


2  Thermo  ... these are the normal....  only engage when the AIR going thru them reaches a set temp..IE  180f   Our fans PUSH COOL AIR


3  Electro-mechanical      Too big and bulky...


  Several years ago...  We tested an "Over-running clutch"  allowing the fan to freewheel  during downshifts /engine decel...


Sadly way too expensive... but worked fine..
