After I got my radiator out, I decided to take out the heater core and replace it too (I think it's the heater core that's in front of the radiator) Attached to it were two lines. One was from the a/c and the other one goes into the firewall. When I was taking the lines out, they snapped off right where they go into the core. What are the names of these two lines and do I have to replace the whole thing even though they broke at the very end??
