Coolant leaking from crank shaft pulley

[Danio]

My 92 S13 has been leaking coolant. The leak seems to originate from behind the crank shaft pulley. Anyone have an idea what the problem might be or how to fix it?

You sure it's the crank shaft pulley, and not the water pump?

almost 100% chance that it's the waterpump weep hole, signifying a near end for your water pump.
go buy a new one and swap it out!

ditto

mine was doing that
hard to see the weep hole unless you know where your looking

but thats almost surely what it is. Get your new pump and change it ASAP

I did it myself in about 4 hours (would have been 2 if I knew where all my tools were)
