My Gen3GSR's heater core finally gave out and I'm asking for advice on how to properly bypass the heater core, I rather not use it instead of replacing it, thanks for the help in advance
Couple these hoses together, using a barbed nipple(heh heh, I said nipple...). U can make a U if you want, with pipe fitting, but its not really necessary.
Just take both hoses off the heater core, and remove one and use the one that's still on the car and run it to where you took the other one off the engine, then it's a cleaner look and you are not having to spend money on new hoses or other stuff.
