hey, anybody ever seen one of these? i don't know if it's a heater or an air conditioner. it's got an aluminum element w/ fins inside and what looks to be an in/out connection for fluid. i dunno what you'd run through it... oil or atf??

That is an AC dash unit.

ahhh... cool, thanks russ. so this may be a dumb question, but what hooked up to those fluid ports?

personally, i think it'd be nice to make it into a heater. it's damn cold up here in boston!

Well, If you had a warm water source, you could make it a heater.
Those were the freon lines that connected there.

think you could (safely) connect the line from the atf cooler? or might you have a problem with the pump and pressure since it'd have to pump it kinda far?

i think youd be better off selling the unit to someone in a hotter climate, then taking the money and buying an electric heater or 'made for your car' gas heater like the eberspacher (sp). here is a link for a similar style NOS unit for a type 3.

some say they are unsafe, because they use fuel straight from the tank, but i dont see how its any less safe the running large amounts of hot oil through a system built for freon.

It also has an AC expnsion valve inside it that would have to be removed.
Beside, VW automatic does not have an ATF cooler.

right, no cooler - i meant pump... but it's probably better not to try that anyway. i think selling it is the best bet.

the type3 autos still have the same oil/atf pump as type1 autos, right? i started converting a beetle dual port automatic motor to run in a manual and it had an atf pump as part of the oil pump unit.

T3's don't need help with heating anyway - unless you're planning to use one for cremations.

well, they may need help with heating if you don't have the heater boxes connected Wink

(mine are connected at the moment, for the record)

This might seem like a simple question to those T3 gurus out there, but me being an almost VW virgin, I'm not sure:
How would you retrofit an A/C unit such as that to a fuel-injected '72, if possible?

I live in AZ and it would be nice to have A/C in this warm clime.
