Default Help please, water leaking only when running

Can someone please help. I have a 1994 GS 300 and I have water/coolant leaking from somewhere an the back of my motor ( at least that appears to be where it's coming from) but it only does it when the car is running. It comes out pretty fast too apparently because I can't go very far before it starts running hot. When sitting in the driveway you can see a leak but it's not that bad. Is there a water hose on the back of the motor that I'm just not seeing? It is a tight fit back there. Any help would be appreciated, Thank you

Yes there is two heater hoses that are in the rear area. One goes from the back of the head to the heater control valve towards the drivers side. The other one goes into the heater core on the passenger side firewall behind the motor.
