I'm trying to find a clear diagram and instructions on how to remove and replace a heater core in a 1993 Cadillac Eldorado 4.9 l please any help would be greatly appreciated
If no one chimes in with the procedure/diagrams, take a look at an online subscription to www.alldatadiy.com - it's the online GM/Cadillac service manuals plus a lot more.
