Just wondering if anyone here done a heater core delete.? Iv removed the heater core and I have blanked off the valve on the back by laser cutting out a sheet for it the valve is on head of the block at the rear just above the box. Just wondering what will I do with the heater hose coming out from the bak of the water pump that runs straight to the back of the engine.? I'm not 100% where this hose goes to either to could I blank it off wish I could explain it better but I can't :( . It's a drift car I forgot to mention in case yer wondering why I removed the heater core.
