    Default Heater Control Valve and Engine Side Heater Hoses

    Hi Guys. I'm in the process of stripping down my 71' 240Z for bodywork and paint and while I have the interior disassembled and dashboard out I wanted to replace my Heater Control Valve and Engine Side Heater Hoses. My question is if I disconnect the hoses from the engine is coolant going to come pouring out? Do I need to drain the radiator before I perform this task?

    I attached some pictures of my progress in breaking down the car. Looking to send it off on Monday to the body shop. Can't wait!!!
