coolant leak from crank pulley... help

[pacefarm]

a bit confused by my situation.. searched a bit, but didnt find anything specific. working on the car lately, and when leaving parking spots, i notice small drops of coolant accumulating on the ground. jacked the car up, and the coolant is leaking from around the crankshaft pulley area. usually gathers up just below it, on the belt. havent driven the car since fall, so quite a bit has leaked already. i'll admit that i dont know much about the coolant path throughout the engine, and if its even possible for it to leak from the pulley.. but, i did a auto-5 speed swap this summer, and accidentally loosened the crank pulley while trying to loosen the flywheel. but i did tighten it to factory specs... any help would be greatly appreciated.. btw, my motor is a ka24de.

thanks!
