    Question G'day from Adelaide Australia (1970 Cadillac Calais)

    G'day one & all.

    I hail from just north of Adelaide Australia and I've just bought a 1970 Calais Coupe.

    It's been a long time coming I can tell you.

    Anyway I am just starting to go over the car and I'm in need of some help identifying things under the hood.

    If any of you can help me out I'd appreciate it.

    Can someone tell me what is this?



    How about this gizmo?



    The centre vacuum line from this thing goes nowhere at present...any ideas?



    hope some of you know the answers, I will buy a manual directly but as you can imagine it's an online purchase or perhaps a specialist book dealer here in Adelaide but it's not something I can just pop down to the local autoparts dealer for...

    Does Australia have a public library system? You may find the publication you need there.

    Hi deVille 33.....

    yes we do have public libraries....

    unfortunately, as Cadillac is not an "official" imported car brand here (GM in this country build cars known as Holdens.....you may have seen them, recently sold in the US as Pontiac GTO and G8) our library (Playford, here in Munno Para SA) and the State Library of South Australia do not have the required manual.

    as I mentioned, online sales or perhaps a specialist bookstore will be able to help me.

    I don't recognize the first contraption but I'm pretty sure it's not original. I can't wait until somebody can identify it. Maybe you could trace the wires and give us a clue. The second thing is a vacuum resevoir to store vacuum. It is usually connected to a vacuum hose leading into the interior for the climate control. The vacuum port in the third pic should be connected to something or plugged. My car is buried in snow right now so I can't go look to refresh my memory. Just make sure the distributor is getting vacuum and none of the other lines are leaking and it should run fine. Enjoy that fine car; '70 was one of the prettiest years.

    The item in the first picture is a very old (probably vacuum tube) garage door opener transmitter. I'll guess its around 390Mhz, tone code. Bruce Roe CLC # 14630

    Thumbs up Re: G'day from Adelaide Australia (1970 Cadillac Calais)

    Thanks for the replies....

    @ cadillac al....goin to have figure out which vaccy line goes to that resevoir (there's a few of 'em under the hood...)

    I have connected the other hose to the distributor where it says D (even an amateur like me worked that one out once I got me specs on...hahahah)....I'd like to simplify some of the emissions / vacuum line stuff but here in SA we have pretty strict conditions on how stock ya car has to be if it is still LHD....

    some of it is a bit OTT (like you cannot replace an iron cylinder head or manifold with aluminium..??) but the law is the law eh?

    @ BRUCE ROE....wow, I never would have come up with that one....V Cool..(IMHO)....and come to think of it there is a button on the underside of the dash near the steering wheel.....now if I could just find a receiver unit for my garage....

    again, thanks for your feedback...

    Alby M.

    The thing under the distributor is (I think) the thermal vacuum switch. It has something to do with drawing vacuum from different areas of the engine due to temperature. D,C and M on it right? Dist, carb and manifold. I disconnected mine about 8 years ago so I'm going on memory, but I think that's the deal. My literature on this motor is out on loan to a good buddy right now, I'll check it as soon as I can.

    @ Angry Matt....yep that's how I've read it mate (hours poring over as many web sites as I can until I can get a manual) and that is how it is now connected.

    Got to love these enthusiast communities....always people ready to help out....thanks.

    The second picture is the vacuum storage tank I believe, it should hook up to the transducer.
