Still leaking coolant.

[Tbuck07]

So I noticed that Im still leaking coolant after bypassing the heater core..so maybe my heater core wasnt leaking afterall? (Exterior of car..) I felt the left side's hose (looking at front of the car) and under the hose I felt coolant..I took the hose off and saw a hairline crack. not sure if that with pressure could cause this leak..but it is on that hose. Where else could the leak be coming from? It drips all the way from there down to under the car..Im gonna replace both hoses just to be sure..
