Heater box/63 Dart

[JimD]

I have a lot of fan noise, I understand you have to pull the heater box out to get to the fan. If I do I'll replace the heater core while I'm at it. Is this a difficult job, I'n fairly handy, any suggestions, thanks in advance, Jim.

if it don't leak, no need to replace it, unless you just want the peace of mind, knowing it's new.
