Radiator Replace?

1985 CJ7 4 Cyl.

I just replaced a cooling fan clutch today, and while doing this, I checked my radiator, and all the little fins are falling off.

I actually ran my finger down one of the columns and they crumbled like bread crumbs.

This must be due to age, but is it time for a new radiator? Would these crumbling / eroding fins have any significant effect on the cooling system in general?

Eventually; yes. Their job is to dissipate heat from coolant by the air crossing over them. When there isn't enough fins to do this, it will overheat. Replace now????? Good question for your local radiator shop.

given the relative ease of a radiator swap, I'd say absolutely. with fins crumbling, it isn't doing much cooling anyway. Soon it will be leaking.

Just thinking if you do replace the radiator. And you should.
Project 23 has a radiator with a built in switch for electric fan. I bet a set of electric fan would help that little engine.
