What is this hose under the dizzy?

[muzukashi]

Car is a 1995 Accord CD5 it overheated the other night immediately after turning on the heater and found 1 of the hoses is leaking radiator coolant

Its a hose that runs from the left side of the block to the back of the engine bay attaching onto another hose, it sits directly under the dizzy and is i'm assuming is connected to the radiator hose from the front end of the block (As it is carrying the radiator coolant through)

I'm assuming its the heater hose as it might've shit itself after i turned on the heater but correct me if i'm wrong

Couldn't get any closer pics as the dizzy and intake arm is in the way but its located here (the pic is not my car some random, but you guys get the idea :))

Yeah thats a heater hose, just replace it and maybe just buy an extra bottle of coolant and flush the old coolant out. Should work fine after you replace that house though.

as above, its a heater hose,

replace the leakign hose and top up or replace the coolant as well. Ensure your thermo fans are workign as well.
