Hey guys, your probably all guys... ANYWAY! Hi, my name is Lisa and I just recieved my brothers 90 cavalier as a gift. I love "her" but the only thing is, is that I have anti freeze leaking and I was told that it was the heating core. Now... my father told me that I can bypass the heating core and the car will be fine. I just wont have heat. But my boyfriend and his Friends say that I NEED the heating core even If I dont use the heat. Now, I know car basics but I deff. dont understand this shit at all. Is my father right? or is my boyfriend... THANKS, Lisa <3
