'92 E-350 heater core time. Any tips?
Well it's getting cooler outside so it's time I fix my bypassed heater core. I got a '92 E-350 box truck. I've done a few heater cores but never a econoline. Any tips or tricks you guys have? I bought the new core as well as new heater hoses as I cut the existing ones to bypass and also they are 25 years old. Thanks in advance.

I've done my own on '97 and later E-Series----not sure how they compare though.
Introduction of the heating/cooling systems using vacuum servos to re-direct air flow and switch from A/C to heating etc made servicing the heater core a bit more difficult if I understand correctly. Sorry I can't be of more specific help.
If someone here doesn't add a few helpful bits soon post your same question in the Heating/Cooling sub-forums----might find very specific info there too.
Good luck with this!

I did my '92 E350 cube (cut-away) last year, I didn't mess with the quick connect fitting, just cut new 5/8" and 3/4" heater hose to fit and used Good quality(Ideal) worm clamps.
Getting the heater box apart on the inside is the worst, once you get the very well hidden screws out
, the problem is solved.
Also, there were several "models" of heater cores, and you'll need to have the one with the correct spacing/configuration of the inlet/outlet pipes, and some models, the pipes will turn to fit correctly.
While your inside that heater box, check the vacuum lines to the servo motor, check the wire connectors, and the wires, and any cables inside, you'll see, after "trying" to get the cover off the heater box why.
