Should the main fan always be on?

The belt driven cooling fan is always on in my car. When I start it up, it's on. When I drive, at about 2500-3000 RPMs I can hear it sucking in air like a fan should.

Should it be doing this? I thought there was supposed to be a clutch that disengages it.

Nope, it is a viscous clutch... It will engage harder the warmer the car gets... Your clutch may be seized though.... My 2.8, I could hear it loud as hell like you describe, but my 1.8, I haven't ever heard it....

I just heard my 1.8's fan when the car is stationary.

With the engine off, try to turn the belt driven fan. It should spin with little effort.

[T3hD0gg]

It spins easily. That's what's confusing me about this. How could the clutch be stuck if the fan is easy to move?

[Ewok_Fetus]

Then simple, it isn't stuck!

The engine driven fans do make a little noise in our cars. Its normal.
