Make sure they save the old bits please - the cooler, that is. Not fussed about the hoses
If nothing else, we could do an RS246 refurb kit on any old ones with a pre-modded cooler and premade hoses for the next person....on an exchange basis or sommat. I dunno.
If you're serious, I'm interested.
As a temporarily solution my mechanic was able to squeeze the whole thing behind the bumper, so it's possible but not pretty as the silver braided hose can be seen behind the grills. I suppose some black high temp paint could do the trick, but that's a bit too DIY for my taste.

I forgot to ask them to keep the old cooler for me to inspect/cut the old hoses of properly, but I will and will let you know.

I'm about to remake my hoses in teflon, inc the long one. Happy to make a few extra sets.

If anyone's got known used coolers, with damaged thread or even flange sheared off, am happy to mod them too. Ive actually got a Tig welder so could maybe put new flanges on.

aRSe.... The garage called me today and told me that they didn't think things were going to work with the DIY route.

........................... my plan was to gently cut twice (180 degrees) into the steel connector end on the rad hose, down to just where you could start to see you were coming down to alu thread, then crack/spread with a big flathead screwdriver to leave the alu thread in pretty well mint condition.......................

.........................................
Thanks.
That's a pity. That process you mentioned was one of the techniques taught when I did my apprenticeship and it is well thought out and safe. I'd use a nut splitter though, not a screw driver. No wonder we're into the mega pound / dollar services when every solution is new factory parts.

Yes, I agree on all counts. Everything has become too disposable

That's how I got mine off. The Dremel paid for itself! Surely the garage could have done it. I just took my time with it and it went ok.

Yep, exactly Steveo, but they were too concerned about trying it. I gave up fighting as we absolutely have to have her perfect before a load of driving over Christmas and here we are.

I have the old oil cooler back, as expected and despite spoonfeeding by me and providing all the bits and tools to do a surgical DIY job, the didn't even try at all, shocker.
It is currently sitting in a big box with all of the pipes still attached Matt, but I honestly don't know when I will have the time to do anything with it. I want to Dremel off the nut just to confirm how piss easy it would have been for them.

What would you want to let me take the old cooler off your hands?

I don't think they want to work on "old bangers" anymore is the thing. Not uncommon with garages now I have found over the last 18 months sadly.

Matt, I would want all the other bits I bought it gone at the same time as they are of no use to me, poss with the exception of the braided hose as I know you don't want that. Let me see how work goes today and I will PM you. Whereabouts in the country are you?

Actually, I might. I use that torques UK stuff for everything I build, so having a few extra AN-8 bits in the "stores" is just fine.
