I have spoken to a couple of different people on here and read a few of the write ups on JDM Climate Control. On a few of them, the heater core was removed without draining the system or venting it in the atmosphere. Does anyone know how this is done? How can the core be removed without loosing any freon?

Any help would be appreciated. Thanks

 

i recently converted my AC to Climate control. If you remove the heater core and evaporator, you have to drain them both of gas and fluid or its going to get messy very quick. Theres no other way, the evaporator is connected through the firewall to the High and Low pressure gas lines, and the Heater core is connected again through the fire wall to the hot water check valve and to the thermostat area and back water transfer pipe.

 

That is what I thought. Thank you for confirming this.
