2007 5.4 Hose Question - What is this part?

[Kevin Edwards]

Hello all,

I was able to find a leak in my coolant system. Attached is a picture. I have circle the leaky part and also the bigger hose piece. Can anyone tell me what this piece is? It looks easy enough to replace but I do not know what it is called. I think it goes into the heater.

Thanks for any help.

Heater outlet hose. Replace that inlet hose at the same time as the plastic couplings tend to fail. The Dorman parts are an upgrade over OEM as they use metal instead of plastic for the couplings.

Part #s:
Dorman 626-540
Dorman 626-537

Dorman is high now.
