The upper radiator hose busted on my Jeep Grand Cherokee so I replaced it and added anti-freeze through the radiator cap. The engine is still running hot, but it also has a bleeder on the coolant system. I am unfamiliar with a bleeder for coolant, I am pretty sure that is causing my problem. How do I use that bleeder and do I enter the anti-freeze through that bleeder as well?

I would just open the bleeder and fill at the rad. Engine cold of course.
