Was driving to work this morning
And truck started leaking antifreeze it screws into top of intake right behind alternator has a rubber hose attached to it my truck is a 99 f150 5.4

I'm pretty sure it's a heater hose. Is it small on the passenger side of the motor?

Anybody

Not heater hose this piece is metal and it screws in to intake has a small branch coming off of it and has rubber hose on it

Coolant cross over... heater hose is attached to it.
