Judging by where it is, I'd think you're gonna lose quite a bit of coolant when you remove it. Just drain the radiator, pull the hose off and put a new one on. I'm not sure if there is a joint by the CAC and you can just remove that lower portion, or if you're gonna have to replace more of the hose. And then refill with the same coolant you drained. Avoid the headache of making a mess everywhere.

 

How do you replace the lower radiator hose? I have a small drip of coolant coming from it and was curious if it’s something than can be done myself I attached a picture circling the blue hose I’m talking about also, what type of coolant should I top off with? It’s currently got a reddish orange coolant in it now View attachment 781513

Where did you find the diagram of the cooling system? I have been looking for detailed diagrams of the major 7.3L systems for years - this one is great!

 

If you have to go as far as to drain the system it may be wise to change out all the antifreeze tyo the new stuff. It may not be that expensive to have the dealer do this repair. I would give them a call and check there price. It's easier for them to dispose the antifreeze than you.

 

That would be the SECONDARY cooling system - the system drain is located at the right side of the front tank.

FWIW - the orange coolant has been replaced by the Motorcraft "Yellow" coolant and can be mixed therefore no flushing is needed. Also, when replacing that hose, it will be easier to access if you remove the grill, headlamps and the headlamp/grill support. There is a temperature sensor in that hose which tend to leak.

And for the curious the image the OP posted comes from the 6.7L Coffee Table Book. Coffee Table Books - Diesel Technician Society (forddoctorsdts.com)

 

Phenomenal! Thank you - those coffee table books have some great graphics in them!
