Freeze damage-interior heater

[bluedog225]

We recently had some uncharacteristically cold weather her (16F). I never got around to flushing and replacing the radiator fluid after buying my SMB used a year or two ago.

Now I am smelling something odd when I run the heater. Back in the day (1980), I had a problem with a car where it was burning radiator fluid when I ran the heater. Smelled like butterscotch. This is a similar smell.

I've forgotten where that leak was coming from.

Does anyone know enough about the heating system in a ford van to tell me the name of the component that shares the radiator heat with the compartment? It would help revive some old brain cells and I could start poking around.

Thanks

Tom,

Are you talking about the heater core?
