I just replaced the heater core on my 89 lx and a couple of things went wrong. (This was my first time so it was pretty sloppy). First, when i pulled out the lower ac line some fluid burst out all around the engine bay, now whenever it runs it starts to smoke becuase the fluid is burning. I've been told thats ok but i'd like a second opinion. Second, after running the heat there are some drips of coolant on the floor. Is that normal or am I going to have redo the whole project?
