Auxiliary radiator

[chocko]

I have a 2014 Fuso Canter 4x4 and am looking at installing an auxiliary radiator to help control engine temps.
Living in Australia and having a GCM of 7.5/8 T is causing some heat issues while on the road all day when it is 35 degrees plus outside.
I am considering a small 300mmx700mm radiator situated under my Tray/box with a draw thru fan or 2 as the airflow will not be the best.
I have installed a deflector under the front of the truck , this has really helped in keeping the cabin cooler but has done very little to help with engine temps.
Cooling system has been flushed and new coolant added at recent service.
Any suggestions would be appreciated.

The other alternative may be to change the existing radiator to one which has more cores. What is the existing one? 3 core? 5 core?
There are also core designs that shift more heat than standard offerings. This pic shows an example. LH is standard 3 core, RH is higher performance 3 core, without restricting airflow which might be a problem with a standard 5 core option.
Also look at the fan performance.

EDIT:
Just noticed that you are in Adelaide (as am I).
Go and talk to the old bloke at Parkside Radiators, 13 Manfull St, Melrose Park SA 5039 (not in Parkside at all). What he doesn't know about radiators is not important

That would be my preferred option.
Less stuffing around.
