What exactly died?

If the fanshaft bearings in the timing cover are bad so the pulley wobbles
you can bypass it by removing the AC compressor belt and reinstalling it in
place of the waterpump belt, bypassing the fan clutch pulley altogether.

If your fanclutch simply doesn't clutch anymore, it is usually simple to
fix, and in my opinion is an excellent system as long as you are using the
all-plastic fanblade and the relieved pulley hub, which is lighter than the
solid one used in 80-81.

If you don't use AC, you can simply use an electric condenser fan instead
of the mechanical one, hooked to the thermoswitch in the radiator, but if
you do use AC there may not be enough cooling capacity with just one fan.

While you have your timing cover off, be sure to check the hardness of the
idler sprocket bolt (many were 8.8, which is prone to breaking--replace
with 10.1), and reset the chain tensioner to its new position, taking up
the slack with the idler sprocket (unless the tensioner shaft is cocked or
scored requiring its replacement, and suggesting replacement of the chain
as well). Reseting the chain will put the camshaft and injection pump back
in time with the crankshaft, and would require resetting the pump to its
original position if it has been advanced previously.
