I'd be looking to fix that with something a bit stronger than superglue.

Or replace the radiator, I'm afraid, is there any way you can disassemble it further and then unleash your 3d printing wizardry to fabricate a new mount?

New rad and pipes required  🙁

Rather than jubilee clips, could you use constant pressure clamps? They seem to be less likely to damage things from over-tightening (at least in my limited experience). And they're a lot easier to fit than Jubilee clips if you have the magic tool.

Love a bodge.  Probs would have gone with epoxy rather than cyanoacrylate!

Superglue is usually water soluble, so probably not a good long term fix.
Top tip if you have overheating issues (and aren't pissing water) is to put the interior fan on full blast with full heat to try and cool things down a bit.

New rad time though I'd say.

New Rad and pipes on order - that was only ever a temporary fix plus the bigger rubber hose has lost all semblance of rubberiness and would probably split if I squeezed it.

Doesn't a plethora of burst pipes normally point to a head gasket issue? Have you got a fluid tester?

Possibly but in this case I think:

The first plastic bracket on the radiator probably had something dropped on it when the car was in my garage and I was replacing the suspension.

The second pipe was moved slightly when fixing the first and released whatever seal it had remaining against the fitting so pissed steam out.

There seems to be a pattern of fixing one issue causes or highlights another...

Might be worth a test anyway - I think the kits are 30 quid in halfrauds. All burst pipes or radiators I have ever had have always been down to head gaskets in the end, so in the event of a leak I test (or get tested) as a matter of course now. I am not a  mechanic though, just embittered by experience.

PS The below stinks of head gasket.

think you've got your cause and effect back to front TBH. leaks cause loss of coolant, which is the medium that transfers heat to the temperature sensor, often with modern, low volume coolant circuits the temperature gauge spikes, but returns to something approaching normal. if the temperature gauge spike is not picked up by the driver, car continues to get driven with no coolant, causing the engine to overheat and HGF.

I drive the car with my ears and nose alert as well as my eyes on the instrument. I built it so know how well it is built. That is why I am confident that the temperature never actually hit the red despite the steam pissing out of the pipes.

If I understand your post correctly I think I agree the blown head gaskets are more likely to be caused by overheating than head gasket failures causing overheating.

Both (Based on cars up to mid 90's, I have no experience beyond)

1) A leaking head gasket, if it leaks combustion gas into the coolant, will pressurise the coolant, and cause leakes/pipe bursting and overheating.

2) If a fan fails or a pipe leaks and it looses coolant and the car boils, this can **** the headgasket.

FYI that is how the head gasket fluid tester works, it looks for the presence of the fuel/combustion products in the cooling water.

Splusn8 - Mine is a mid/late 90s car (1997) and my (limited) experience is that 2 causes 1 rather than 1 causing 2 and I am hoping that is truw because I don't want to take the head off my straight 6 engine.

leaking head gasket can definitely cause pipe burst, rads leaking, ask any mexhanic. I hope it is not gone, but its easy to find out.

buy a head gasket tester  https://www.amazon.co.uk/COMBUSTION-LEAK-KIT-PETROL-DIESEL/dp/B018PM3ZFQ

it will test the coolant water and tell you if its gone.

With that you have described pretty much every car I owned till the late 90s 😀

Long summers, windows open, nearly stripped naked and sweating cobs in a nice long tailback on the A30.
