[9.0 RS lava]

As I was trying to replace dead battery last week. I sheared off a hose to radiator and the nipple that was attached. Is it true I must replace entire radiator or can this be fixed?

I'd replace the radiator. They're cheap enough nowadays- plus if you fix it and there's a small leak or rupture- it's overheating time for the box. Better safe than sorry. My .2 cents....
