Leaking coolant.

Please help me identify what it is leaking.
Volvo 2009 whit ISX
Leaking something what is attached inside the frame on passenger side. Four hoses connected, two connected to the pipes from the rear of the engine block and two to cooling system. Right now is dark couldn't see anything good what is leaking. Hope it's a rubber.
Can I bypass this thing??

 

Thank you all guys for help. Yes it was a power steering heater. One of the rubber hose to connect heater core and pipe from the rear of the engine.
Bad thing it's happen in rural south Illinois area at night. Next day was driving really slow to the nearest Walmart. Got big enough container to drain coolant and 3/4 inch diameter rubber hose from O"Raily auto parts.
To drain coolant from radiator just use 1/2" garden hose, drive phillips srewdriver inside along the hose in a couple inches from the end. Then slide hose over the radiator drain nipple and push valve with screwdriver. Don't forget to put other end of the hose into container.
Real problem was to fill system with coolant after repair. Total coolant loss was about 5 gallons and no final charge red coolant available around. I put some final charge but pink in color. Have no idea about can it be mixed or no
