The easiest way to change heater core
In most cases you have to tear most of the dash out and remove most of the ventilation duct work. I have seen cars where the owner cut the ductwork out with a saw and replaced the core and then used duct tape to put it back together. I dont advise you do this . Its usually a long and involved job. If the core is not leaking ,just not producing any heat try this video before removing the core. Its a whole lot easier than replacing the core. Hope this helps
