To remove my oil cooler i had to cut through the hoses as the unions are badly stuck on.

I have now reached the point where i need to fit the oil cooler but am unsure how to rejoin the hoses. They are 16mm id. Anyone got any idea's?

Are they the braided/multilayer type?
By 'badly stuck on' do you mean tight or kluged?

Kluge = bodge

I've just fitted a cooler to my autobox. It's pre-owned and came with approx 24" long braided 1/2" ID hoses but unfortunately they were too short to reach the front of the car. Whereas I could have extended them I started from scratch, getting new fittings, steel tube and oil-tolerant rubber hose. The autobox cooler loop is quite low pressure so it all seems OK.
Does your hose have crimped or manufactured ends? You might be able to salvage the end fitting and fit the cut hose onto it, but not sure about the integrity of the resulting joint.
It all depends on the pressure in your cooler loop, but I think you'd need swaged or barbed fittings and something better than Jubilee clips.

Its crimped

I don't understand what you are saying.

Most OEM coolers have hoses swaged onto the oil cooler e.g. MGB - they are not removable, and if you succeed, chances are you won't be able to reconnect unless you can clamp a hose onto the pipe.

after meerkat one will have bolt on fittings - these are removable.

This is a pic of another cooler i have. Its the same one but the one i am using has two metal pipes attached with hoses attached to those pipes (crimped i think).

The nuts at the bottom of the cooler will not turn at all so i need to join the pipes on the cooler i am using onto the pipes already on the engine.

I have extended my oil cooler lines, which were prebent steel tube, and braided lines. I have cut through the steel tube with a pipe cutter, and extended it with compression fittings and some aluminium tube. It seems to be working sweet as at the mo!

I have to admit thems does look like nuts - you can definitely see some thrread or a join so they are not crimped?

If you are feeling brave, hacksaw or grind a slot in the nut to weaken it in the hope that the fitting is standard thread, most liekly 1/2 BSP and then get new fittings - in steel they won't be too £££, maybe a fiver.

You have tired heating the nut ? and have water in the cooler, then tip the cooler so the inside of the nut is cold whereas the outside to hot and try to undo?

DO not apply too much force if you cannot gain a hold on the cooler outlet or else you'll damage the cooler.

I see hex part between the cooler and nut- can you grip that? Needs a thin spanner or make one from thick steel?

I'd chance it and cut one nut off.
