Cadillac Repair: Heater core, heater core, dash board

Question
I have a 1998 Deville I am wondering do I have to take the dashboard off to replace the heater core? And is there a manual showing how it is done?

Answer
No you do NOT have to take the dash board off.

You will need picture locations of the components within the system that is causing you problems of which can't be done on this website which only allows one picture. I do not have a website so you will have to e-mail: onlineautohelp@msn.com in order to obtain the information.
