Can I replace the heater core in my 1986 B250 without removing the AC evaporator? It still has R12 and I do not want to lose it.

Not sure. There are two front HVAC units desinged over the years for the Ram Van. So, 1977-1997 and the 1998-2003. One of them the AC system has to be opened, the other I believe does not.

I went ahead and moved this thread so more people can see it.

Thank you, next question; Can it all be done from under the hood or do I need to remove ductwork from behind the dash?
