So I just purchased the UTV Inc. water temp gauge and sending unit. I cut the hose, just as described in the instructions, and all the antifreeze came out. I figure that since I the majority of it came out, I just might want to completely empty the radiator and clean it out. I want to replace the regular antifreeze with Engine Ice. So my question, How in the heck to you completely drain the radiator? I tried to find the drain plug, could not find it. I looked and looked and could not find a place were the fluid can drain. Do I need to remove the radiator completely to drain the fluid? Some someone point me in the right direction.
