When I first got my t4r, i was losing coolant and it turned out to be the Idle air control valve. Something to check if you are going to have a shop fix the heater hoses. I ended up bypassing mine since I live in a tropical climate.
Unrelated to the problem at hand, but are those hose clamps OEM that have the cotter pins in them? Ive never seen a hose clamp like that. Just curious.
