Help ID part coolant leak

[M1rodrig1]

Please help I need to replace this part. I am not sure what to look for. Is it a whole assembly with the hoses? It connects to the firewall on the passenger side. It is leaking onto the coil pack and spark plug and causing a misfire.

You didn't say what year or motor this is but that's a heater hose. The tee is is usually for the rear heat. The hose is sold as an assembly and is attached to the heater core at the firewall with a "quick connect" that requires a tool and patience to remove. The hose clamp looks like someone meddled with the thing in the past, as that's not stock.

Sorry the year is 2003 and the motor is 5.4.
I removed the original clamp and placed that one just to see if the leak would stop. It kept leaking so I think it's the T that the hose connects to before connecting to the hose that goes to the firewall.

This is the part I need to replace I think.
