That's the bypass hose.

It is rarely replaced when people replace radiator hoses, so it is not uncommon for them to eventually fail due to neglect.

Unfortunately, it is a bit of a, ahem, bear to do. Slick did a nice (and colorful, as I recall) write up on it in the past.

 

I did mine as PM while I was doing the timing belt and water pump so it wasn't nearly so bad.

 

Most of us just get a generic formed (tight right angle) hose at Napa. Bring in the old one, match the ID, and then cut the ends to the right lengths.
