Hello\nI apologize for what looks to be cussing with my name. I was setting my pass word and didn't know it was with my name. Can anyone tell me how to edit my name?\nFor the question I'm posting is for a 1999 Saturn Sl2. I need to replace the aluminum line that goes to the heater core The line comes up from the firewall over the fender well. It hooks up to the coolant reservoir then goes down and connects to a heater hose that connects to the water pump. I don't know what it is called. Does any one know what it is called?
