yep, the amount of air flow..... :D
Hey, why don't you go open the hood on your newly purchased Ram. Let me know if it has an electric fan or a belt driven fan. After you discover "what drives" your fan, I'll let you guess why
:lol:

When things need to be cooled because they may have to work, even in todays electric world they are still belt driving fans :D

Hoping to learn something here..

I always thought that electric fans always run at the same speed and the blades do not change pitch. With mechanical belt driven fans , the fan blade pitch changes with speed and if equipped with the viscous clutch it actually cuts out when the fan is no longer effective.

Looking forward to any comments.
