Howdy All,
I've seen in some pics of LX's that some had an overflow bottle for the radiator located near the windscreen washer bottle. Were these on the series 2 LX's if there is such a thing as mine (which is an early built date) doesn't have one.
Man I dig this website because it answers all my questions, administrators keep up the awesome work!!!

Dont know the answer exactly, but thought the recovery reservior was perhaps only a aircon option.
Regular Uc didnt come with a recovery system either.

My LX has a recovery unit, i got the bracket and bottle of a UC at the wreckers and bought a new windscreen bottle from supercheap, it does the job.

It's not a standard thing, it was something you could buy as an option though, became more common on the UC after being standard on A9X

This custom set up looks neat IMHO.

I went to Pinch a Part and got a setup out of a Volvo for $6. Why Volvo? because it was the biggest setup with a bracket I could find on the day.

Hi Hux,
Yep what RedA9X said is spot on again. mine is a Late May '77 build (series 2 as you put it) RTS update as some others put it, and it does not have it. Also if you look in radiator cap reference/parts book for LX V8 as I had to recently they are a non recovery system cap.

And your right this site is great for answers and Red is like a Torana Bible.
Thanks Again RedA9X

Regards
Duck05

I used a UC item, lands on the LX screw holes. 0 mods or drilling.
Only have to extend the bottom bracket to the charcoal canister clamp.
And buy a recovery radiator cap!
Mine came from a stock, non air-con sedan.

the originals just look like a washer bottle and mounted in the same place on the other side of the car.

hrt1and2's photo shows an oem optional fitment for UC. I haven't seen it on all UC's but I have seen it on quite a few - I think more 4 cylinders than 6 cylinder UCs. I haven't seen it on any LXs as original equipment.

There's a "T" shaped metal bracket which screws into the the holes that normally hold the single reservoir to the inner guard, and it also mounts to the carbon canister clamp. One oem washer bottle is mounted on either side of the steel bracket - one for windscreen washer, and one for radiator overflow. The metal bracket looks a bit cheap and nasty, but I'm sure it is a Holden part.

hi there. I got the bracket off an UC. but when i put it in ruby i thought it looked off balance :rolleyes: and took up too much space. so i got a smaller bottle and attatched it inbetween radiator and charcoal canister. works 4 me. :rockon:

Hux if u want the bracket u r more than welcome to it.

I have seen them before with one on either side of the engine bay, eg. the overflow bottle is a mirror of the wiperwasher bottle

Hi all

I have had the UC Setup that people have discussed, see pic below.

While it is a good setup, I found that the recovery system didn't work that well. It would spew out from the top of the cap that had a hole in it and onto the underside of the bonnet.

As part of the rebuild, I will be replacing this system with the "A9X" type recovery system. This style is still available from repco and IMHO I think that it is a better system..

cheers
Mick

I believe that is standard operation, not sure if the holes were drilled out after the install at the dealers as both the recovery systems that came standard on 2 of my UC's look drilled out.
Ive got around the sudden release of the coolant/overflow prob by simply putting a baffle in the reservior. You need something that can be squeezed through the opening and will float in the water rather than sink and block the entry/exit hole.
Ive had a simple piece of foam rubber in there for 15 years, it hasnt degraded even with normal castrol antifreeze mix in there.

I guess the bottle simply isn't as big as it needs to be and really should have an overflow hose the same as the A9X one does. Another thing is make sure you only fill it to the min line.

The problem isn't the actual volume of the container, its the design fault that the entry passage is directly beneath the filler lid, so when the rad cap suddenly releases........not all release slowly......a fountain of coolant goes directly straight through the container, blowing the lid off if there is no oversized hole. As stated in my previous post an absorbant baffle will correct this problem.
It still needs a large hole in the lid to get rid of the air quickly to allow for the volume of the incoming water,
Im not familiar with the a9x system, how does the overflow hose design differ to correct the problem?

A9X bottle is designed to be an overflow bottle. The inlet is horizontal and at the base of the bottle, and the overflow is on the top corner, opposite the inlet. An overflow pipe is attached to the overflow outlet and fits through a hole in the engine bay, so it exits under the engine bay.

Thanks for ^, a picture's worth a 1000....trying to imagine how a hose itself could be different, get the idea now.......there are 2 hoses connected to the bottle.

Upon reflection it does seem incredible that GM even let the UC style one go to the market at all. It is really quite dangerous, perhaps they did get sued when someone was scalded by the erupting fountain?

I brought another one of these a couple of weeks ago and it was around $40..

the reason I now have two??? You see Bars (the maker) only supplies one bracket in each kit. These brackets need some mods if they are to be close to the original brackets.

I am currently getting a set of brackets modified to match the A9X ones..

cheers

RED, that's one tidy engine bay, from the looks of that pic. I look forward to seeing the beasty in person again one day.

Was it my imagination, or were you going to get some replica overflow bottle brackets made up at one time?
