Default coolant leak

while changing my rear main seal i noticed coolant dripping off the front of the oil pan. the hoses are fine. could this coming from anywhere other than the water pump? there are no visible leaks looking down from the top of the motor. is there anything under the water pump that could be leaking?

Could it be that back 90 degree 5/8 hose off the back of the canister on the pass side, there are 4 of them 90 degree bastards on the 1st gens, not to mention the little shitty 2-3" pieces. I just changed all mine.

Also, check the block heater port on the side of the block. The bolt broke on mine, was an easy fix though.
