Hi all,

With living in the tropics, I have been thinking of beefing up the cooling system.

XT radiators are not available from OKA anymore. Has anyone beefed up their cooling system with larger core/row radiators?

Cheers

i cant see why you couldn't get a custom ally radiator both with more cores and wider should be less than $1000.

Yes I was thinking of PWR, but I think the cores are a odd size/

Hi guys,
How did you go with the Alloy radiator? I've got my 20 year old copper rad out and have to recore it and it's pretty expensive! Looks like i can get a generic Aluminium radiator for the same if not less! (i have a TIG so can weld on brackets etc) Any thoughts?
I got told by the radiator joint not to get aluminium if i'm going outback as they can't be repaired easily but looking into it there's a lot of epoxy glues that do the job and would in theory be easier than getting out the oxy to braze up a copper core! They even use them on the big CAT earthmoving equipment. The question is, how well do the glues work? Any experiences out there?
Cheers,
Alister

Most of the 4wd's these days use ally cores with plastic tanks and while they are a bugger to fix if you get it really clean etc the epoxies do work as a temp measure. If you poke a hole in it though and say damage two tubes you just can't crimp them off and solder it up like you can on a copper/brass job. We had limited success on cruiser a few years back when a stone punched through the core we could stop it leaking as long as it was unpressurised but the epoxy let go if the cap was locked down. Couldn't advise on the epoxy except it was specifically for radiator repair, all in a kit with cleaner etc.
A better idea for alloy repairs on the side of the road is those rods that the bloke demonstartes at shows welding up coke cans with an LPG torch. I've welded high pressure side power steering pipes, a thermostat housing and an alloy sump with them in remote locations and affected permanent repairs, they work really well and don't need a huge amount of skill to use either.

I forgot to add that one of the biggest problems with outback use of alloy radiators etc it the etching the red wet soil does to alloy if not cleaned off promptly, will eventually eat right through thin stuff.

I am still looking at options.

My problem at the moment is the viscous fan hub I think. But would like to beef the radiator up sometime.
