What is this radiator hose for?

[alexpops]

Does it connect to the water pump for coolant circulation before the thermostat opens?

If it is anything like the GC series, then it is literally the cooling system drain line. One end attached to the radiator, the other end attached to a plugged barb with a hose clamp. When you need to service the cooling system, open the radiator cap, remove that line and hold it over a drain pan...all the coolant drains out without much mess.

Huh - I have a 2001 L3010 also and always wondered what that hose was for. Now I know - Thanks !
