Hi everyone, i know this subject has probably been frashed over and over, but i do have a hole in my Radiator and i will need to replace it soon.I have a 99 coil cab Patrol 4.2 Diesel and its the original Radiator Allumin.Ive done some homework and the originals are pricey, and i dont want to go Allumin.Im told you can get Brass,copper for a fraction of the price,is the one in it now a 3 core and how big can we go?? Im thinking the bigger core the better for our long hot summers.
For all those Patrol lovers out there like me we know they get WARM i dont like to use the term HOT because theres a big space on the guage that indicates normal operating temp range, outside of this is that letter H if it gets in there you are in trouble but we all look at our gauges, often dont we.
Thanks guys in Advance I look forward to hearing from ya.

Quino,
I am no cooling system expert, but I believe that operating temperatures are critical, and that the thermal efficiency of aluminium cored radiators is vastly superior to the older materials. Moving away from the original would be a serious mistake. Better to bite the bullet and replace with original part.Bob

Try PWR they make all manner of custom ally radiators, intercoolers, oil coolers etc. they are owned by the guys that run the paul weel racing v8, they have a great rep for quality and could make you an upgraded unit so you could kill 2 birds with the one stone... Brad

You will be millions of mines ahead if you just spend the money ONCE and go Ally again..

IF you spend the 'fraction' on another crap one, and it doesnt work, you will have to go ally anyway, wasting 100's..

Cooling is critical, and 1 radiator is cheaper than a new engine.

YMMV.

I also am no cooling expert, but my understanding of aluminium radiators is that they provide little in the way of extra cooling efficiency. The reason they have introduced aluminium radiators is simply to save weight.

weight and $. Cheaper to mass produce according to a friend in the automotive game.
Aluminium is more susceptible to "stray currents" ie: electrolysis.
None of which answers the original question, does it!
Sorry I don't know the answer.....

Another incentive was the OH&S issues involved in working with lead (solder) Europe and Japan are even changing over to completely lead-free soldering for electronic products, as the lead in scrap electronics is starting to cause a severe problem in the waste stream.

Quino.

Aluminium is the prefered material because of corosion, most of the motor wet areas are aluminium and there is less corosion between similar metals. You may notice that the thermostat is monel not brass on a modern motor for the same reason. Eric.

Eric, I was told by the local radiator shop that aluminium is more susceptible to electrolysis.... depends on who you speak to...... but maybe you're correct??? Who knows?? Maybe it varies depending on Cast Iron or Aluminium Block/Head.??
I'll have to do some research now as you've aroused my curiosity!
Cheers
