So, I'm about 2 years late to party, but I thought I'd share.
I bought a tool that's designed to remove hoses. It's a long, thin pick, but it's bent like a hook.
You use it to get under a hose (like the radiator hose), and free it from the barb or nozzle that it's connected to.
This little tool has worked wonders... it was so hard to get a small screw driver or anything else in there.
The tool does it's job.
Attached is a photo I got off of amazon. They call it a "hose hook pick".
FYI, in case anyone needs it.
