Hi,
I had my rad burst last week and thought whilst it was out of the car waiting for my new one, i'd have a go at the engine oil cooler pipes which were leaking from the metal pipe to rubber joint.
I was going to dremel the metal collars off and just replace the rubber hose with worm drive clamps as when I tried to get the pipes off my auto box wheelarch cooler they had galvanically corroded onto the threads of the cooler (steel nut onto an aluminium thread - genius!). I had to replace the entire cooler as the threads just stripped.
Anyway, I dremelled the collar off expecting to find a bead form on the metal pipe underneath, which would then be fine for a rubber hose pushed over it with a worm drive. However, cheap and cheerfull as usual, it's just a plain pipe without a bead under there.
So seeing as I had the rad out anyway, I took the intercooler out and then removed the oil cooler from underneath with the pipes still attached. I then dremelled each side of the nut (carefully) and peeled it open off the thread of the cooler.
I found that it's only the last couple of threads that corrode to the nut. It's the action of undoing the nut that ruins all of the other threads on it's way off. If you cut the nut off, the threads are mostly perfect underneath, just the last couple.
So using a hacksaw blade i cleaned up the corroded threads so that the new pipes wouldn't bottom out on them too early, and screwed the new pipes on. job done, new pipes fitted, no leaks, and no need for a new oil cooler due to damaged threads - result!
