    Hi All
    One of the jobs i've got on the winter list is possibly reinstating the original heating.
    But i have no heat exchangers, so that's the first thing i need to source, can anyone tell me how to tell the difference between original and copy exchangers ? (without cutting them in half :D)
    and maybe if anyone has any gathering dust on the other side of a garden fence
    1600 twin port AS code engine

    Thanks in advance Mike

    Originals are heavier, with much wider fins inside. They may have "VW" stamped on them.

    would that be the only difference looking on the outside ?

    Best way to ID them is to look down the big hole where the heating air pipe fits: you can see the fins. Originals have big, full-width ones, repros rather stumpy skinny things. Can't tell much from the outside.

    Worth getting hold of some if you can find them: big difference in heat output.

    Also worth finding out ....if there is asbestos in original H/ Exchangers on a 1600 twin port .
    Because they are deffo in original type 4 H/Exchangers

    You may well be able to remove it out as you can with type 4 ones ....making sure you soak it all in water if you do .

    i suppose that why the PO put J tubes on ! is it worth putting new ones on ? for the money/time spent do you get much heat ?
    I will also have to replace all of the connecting pipework to the front...
    shall i just fit a propex ? it will have to be able to operate while driving (I'm sure Mrs Bluerustybucket is cold blooded)
    decisions decisions.....:confused:

    The heat exchangers that were on my bus were the most likely cause of the exhaust fumes getting into my heating system - I've no idea if they were original or repro, only that they had to go!
    I bought a new set from Schofields; most of the usual suspects sell 2 grades of repro now, but sadly I couldn't warrant the cost of the (allegedly)better quality ones, so went for the bog standard.
    No more exhaust fumes, so much less likely to die in my bus (always a bonus!) and they do stick out some heat.
    Having said that, obviously it's been summer so the heating's not been so necessary, and I don't have much to compare to as I got gassed everytime I used the older ones.
    I do think that the cheap repros have more like a spiral of metal inside them, rather than fins - so you might be better stumping up for the more expensive ones if you're gonna do the job (assuming they still have fins, albeit more stumpy than original)

    Yes it's worth doing. Even the repros give a waft of warm air. The genuine ones blast heat out.

    Thanks @snotty. Could you just have a quick look over your fence ? You never know

    Your going to have a hard time finding original exchangers that aren’t rotten
    There was a company in the states selling high output repros a few years ago but I can’t remember the name

    There's no asbestos in the heat exchangers themselves, but there is some grey in the corrogated body tubes IIRC.

    As i thought, you can see why there is such a difference in heat !
