How do you replace a heater core for a 1990 Cadillac DeVille?
DavidRHulingSr
Remove glove box to get better access. It takes a few minutes to unhook the vent tubes and heater mechanisms, but you will finally get to the point of opening the black plastic housing. There you will see the core. Remove the one bracket that is still holding the core and the two hoses from the engine side of the firewall. A little manuevering and the core should come free. I replaced mine three times before realizing the thermostat was causing overpressure and apparently the heater core gives up first.
