Power Steering Belt: Removal? Are two belts better than one?

[Dan]

Howdy,

I have a 1978 FC33, 3208NA, with disagreeable power steering (noise,
high effort).

I want to replace the power steering belt to rule it out. So I
checked the files on this forum which state "2ea", My pump has one
belt and a one-belt pulley. Note: there is an un-used V slot on the
Crank Pulley, possibly intended to drive the PS pump. Can someone
solve this mystery? Any advantage to two belts?

In looking at the belt, it is behind two other belts, which go up to
the fan with no obvious way to induce slack. Do I need to remove the
radiator to change the PS belt? Is there a procedure (or diagram)
someone can share with me.

Thanks,

Danny
