Hi, I need to replace my upper radiator hose since coolant is leaking out of it. My question is do I need to drain all my coolant to change the hose or should only a slight amount leak out that I can just top off?

If you have the time go ahead and flush it and refill the system. As for a quick fix you can put a drain pan under the hose and pull one side off it will just lose a little bit. Put the hose back on and refill.

change it, top it off, run the car with heater on and rad cap off for a bout 20 minz... the colant level will lower, just fill it up every time it goes low
