The heater core in my 1977 D100 (no A/C) started leaking yesterday, and completely soaked my carpet. Before I attempt to take everything apart to fix the problem, does anyone have any tips for what I need to look out for when I take it apart? Any suggestions would be appreciated.




I have a complete firewall that I from a 77 you can come get or practice on. Still has the heater box. Going to scrap soon.

Pretty simple too. Depending on brand, the replacement heater core fills the whole plate. At least on my 72
