Is the hose supposed to be in the picture?
Are you talking about a main radiator hose? Swing by your local dealer and pick one up.

Either way the radiator screen needs to be cleaned.

Did it overheat? Looks like the rad is packed with grass.

The only coolant related hose I see in the picture looks like it is the overflow tube.

Something is wrong in his picture…

There is a radiator overflow hose (marked in yellow) that connects to the overflow reservoir (marked in green).

There appears to be a hose (marked in red) from the radiator to the overflow reservoir but I am assuming that it is in two pieces and split badly. So replace the red hose #70 and add some coolant to the overflow reservoir. Probably need to add some to the radiator also since I assume it boiled it all out.

I would probably change out the reservoir cap and everything attached to that cap and also the radiator cap.

@Russell King I thought that (in red) around the rad was some type of seal/ rub rail for the hood to rest against.
Anything is possible, it just looks like a split hose to me…and he doesn’t show any particular problems in that picture that I can spot. So from a few thousand miles away I took a hard swing and may have missed!
