Default Re: Fan Belt Speed (pulley ratios)

The question is can anyone tell me since the belt sits lower in all of the pulleys is the fan speed unchanged, faster or slower?

I do have an over heating problem which I think is actually a new (used) radiator but the fan speed question bugs me.

Thanks
Fan speed is not your problem. You should be able to drive down the road with out a fan with no problem. You need the fan for stop and go traffic, or idling.
