    Default Need HJ-WB gurus! factory/dealer? fitted aircon unit

    Good old Gumtree is all I can say. Ive been chasing aircon for my Hz ute. I was going to run a vintage air system but once priced for everything its gonna cost over $2000 and I want to retain as much of a factory look to the car as possible. Yeah I can do it with the vintage air but again high price tag.

    Answered an add on gumtree for a fully integrated factory system pulled out of a HZ. The seller had bought it from his neighbour who had removed it from his car as put a tuffy engine in. He bought it for his hq but apparently didnt suit underneath the dash as they're different so was reselling.

    What he had was not even close to what he had pictured for sale as he only had a shot of a clean wb engine bay with the factory aircon. The compressor bearing seems good and was apparently recod but rest of the supposedly recod items such as powder coated engine brackets are just black enamel from an aerosol and badly painted at that (told the guy I was a spraypainter by trade, like I wouldn't know?). I wasn't even sure if it would fit under the dash or connect to the existing system but after a 2 hour drive took a punt and bought it for $600. Everything seems to be there.

    As far as I can work out once getting it home its not the integrated system that I wanted as I already knew but fits in place of the left had air duct from the plenum before the blower fan allowing cooled air to be pulled through from the blower fan through the existing blower and heating system.
    I found a hx for sale online running the same setup and Im assuming this is a dealer fitted option to have a somewhat integrated aircon system rather than a 'factory' system.

    Im also guessing its not very efficient but I only have to cool a ute cab.

    The compressor sits high on the mounting brackets and wont even clear my full factory fan shroud or taller rocker covers. Not to mention its not tidy enough for how fussy I am. I have bought a sidemount compressor bracket for the 308 to solve that problem.

    On a plus side if it works ok interior wise its actually a tidy way of me putting in aircon without changing too much out.

    So just want some information on what the setup is and peoples thoughts on it.

    Pictures bellow the unit and compressor and a photo of a photo on the engine it came off. Don't know why he didn't put that pic on gumtree, would have saved me 2 hours.

    Looks to be dealer fitted although i think that setup is far neater than any other offering that they ever came with. Granted you loose some glovebox space but it overall neatness is a winner. Did you also get the vents supply pipes for it as they are different. I have one of those units in my shed, i paid $150 for it over ten years ago from the wreckers and was told they were quite rare, i then found two more at the tip which i kept but have since lost.

    No it uses the vents of the existing system. Under the dash on the lh side is where the air intake goes to the blower fan. This replaces that piece. In the heater box itself theres a divider for heater or just air so this is before all that. It looks to fit albeit tight but behind the glovebox.

    Mine has a set of different plastic soild ducts as the original are those flexy things. There is also a plastic blank off so when you cut the glovebox to make it fit it finishes it off

    Hmmm is it possible to take photos of any of that? Bit strange they changed the ducts from the flexi ones. The fan only blows through the 2 center dash vents and I wont need to change any of that. The outer ones only work for open air coming through the plenum. Fitting this unit means I will lose the open to air vent on the left side in relation to the left dash vent leaving it doing nothing. Do the solid plastic ducts follow through to the outer vents as well? Theres also a cable controlled flap on the unit that seems to block off incoming outside air to the aircon unit and open it up to the cab so Im thinking this is recirculation.

    Cd player and b&m coverter control unit for the 700r4 is in the glovebox anyway so not to worried if I lose a bit off space there

    That pic you posted of the engine bay is a old idle wheel set up, from the Ht,hg or HQ's i think...The HZ,WB bracket is a better set up for under bonnet...I have uploaded a cpl of pics of the old GM type compressor with factory A/C (2nd pic) that suck a lot of HP and a pic of the Sander type compressor with a after market A/C that fits up under the dash and is hard to tell it up under there....the after market one ducts air out all 4 face level vents via flexible tubing...The first pic (Sanden) is a way cleaner looking unit as you can see.Try getting No8 plug out with factory unit from the top...lol





    I know you have bought a unit now and have to run with it but this for others maybe and for later reference.

    HX Holden UTE V8 Auto Aircon in Penshurst, VIC | eBay
    found this ute on ebay seems to have the same setup. Check brackets and standard heater box. So it must be something offered. Perhaps whoever made the aircon units for the early girl holdens did this kit for the dealers and re used the engine brackets?

    Yep thats the old bracket with the idler wheel....the later model ones fit lower over the alternator and don't have that idler tension wheel set up... it will make no diff to the performance but it just looks neater.

    Thats not a factory A/C...just look ate the heater controls...there are no A/C on it .The A/C switch is on the left.Its a Sanden type compressor too.
    This is a after market type....you just supply the compressor bracket by the looks.

    No the heater controls stay the same and a switch is added to turn on the aircon. Im just interested to know more about the kit. The one on the ebay car is exactly the same as I bought. Same compressor too. The seller told me it came off of a hz sl wagon and was from new with an aircon pack which makes me think it was something supplied and fitted at the dealership. No idea why they would use the old compressor bracket though.... under the dash it fits as an add on to the existing system so its made for the car. Not justba universal application.

    This is the vent setup all though not 100% complete it replaces the flat plate with the two ports on it from what I remember, also forgot the pic of the glovebox blanking plate. It not really much different than just fabing up a few ducts to the existing vent

    This is a standard heater control with NO A/C



    This is a dealer or factory air con control.........No GMH dealer ever put in any other type of air con in their cars than what was on offer by parent company.....So that switch on the left is a after market put in by a garage down around the corner. Unless Smitty says otherwise....lol.

    Thanks matty12. Yeah wont be too hard to run some tubing.

    The factory aircon switch wouldnt work for this anyway as its electric only, not vacuum controlled. All i can say is if its truly aftermarket its awesome. Replaces an airduct to make an integrated aircon system out of the standard blower system. And had ducts and glove box blank etc its truely had thought go into it.

    I know you have bought a unit now and have to run with it but this for others maybe and for later reference.
    aaah ..history lesson maybe.

    Since the really old horrible system used (like I am going back to HK/T days) GMH swapped to a reasonable good .. but power sapping
    large black compressor (and matching HUGE Evaporator) system sourced from 'HARRISON AIR' in the good ol'USA
    It worked very well on HXs and HZs, even VB Commodores** but turn it on?... and about 50% of engine output was required to drive it.
    Worked well on 7 litre Cadillacs in the USA and but was needed here due to our heat (in the outback) or humidity (think FNQ) and did work well here.

    Come XT5 engine time (Improved performance 'blue' motors) and something in this area had to be done...as the Harrison HVAC system
    just nobbled the engines. So the HVAC system was put out to tender ( i was on the Supply committee evaluating this new system.. for price)
    and Air international won.. with a new generation 'lightweight' SANDEN (aka... SANKYO) aluminium compressor and in cabin evaporator
    and nice light aluminium condensor hanging out front. So into VC with the new blue motor it went... but what about existing 'in stock'
    HARRISON system you might ask???

    Easy lets stick them in a special run of cars to get rid of them... yep they all went into HDT 'Brock' SL/E VC Commodores.
    Way to go GMH

    Finally... just one point, the Air International receiver/dryer (the black tube looking thinghy with the sight glass on top) has a life span
    of maybe 5-7 years whereas the large silver HARRISON one lasts longer.. maybe 2-3 times longer. I know people running them in Holdens
    from the mid -late 70s and they are original !

    that help???


    **
    ps.. did I ever mention the story about converting the LHD Harrison system (used in USA and Europe) into a RHD Commodore??
    well.. it all started by turning (flipping over) the evaporator assembly (in the cabin behind the dash) and woohoo it fitted... no problem.

    There was unfortunately one BIG problem with that piece of GMH engineering brilliance! Anyone wanna make a guess???

    hmmmm outlets face the wrong way?
    I had a look at the unit just before. It says on the side Air International Melb, registered design RD70897

    So Im guessing this was an aftermarket kit offered by air international? The VC would still coincide with the WB ute. is it possible this was sold for the WB and people refitted to earlier models?
