So I have a 1999 S80 T6 and everything is great, except the Heater Core is leaking! I found it but I cant find any way to get it out. Does anyone know how I can go about doing this? After taking apart the passanger space and seeing the little leak I still could not see how it can come out. So if any one knows I can please send any and all info I would much appreciate it. Try to respond to this blog and if no luck then try my e-mail, thanks acarsey@gmail.com
