I have owned this van since it was new . My heater core is leaking through the box and I need to replace it. I have disconnected the hoses and cable lines to the heater control on top of the box and unscrewed the attachment screws, and pulled the blower assembly out of the box. I need to get the plastic front facing off but it doesn't want to be removed! There doesn't seem to be any bolts that I missed so I am wondering if there is some sort of "catch" that I'm not aware of.
How do you get the old core out?

I did one about 30 years ago. I'll have to think about it.

I think the heater box is bolted to the firewall, and the core has screws up through. If your machine has AC it may be vastly different from what I remember.
