Outer Limits 4x4 Board

Is the standard Twin Core Aluminium / Plastic radiator the largest available for this vehicle? Is there a 3 core aluminium? 4 Core Copper?

My Turbo 1HZ overheats when flogging piss out of it with 3Ton of trailer behind. I want to make it bulletproof. (Havn't tried my own fan clutch solution on this vehicle yet though)

It has been cleaned (tanks stripped to fit auto trans cooler)

Thanx

e few blokes I know have had issues with the radiator blocking, one was almost new.

try getting the radiator flow tested first, otherwise thereis a few option for other radiators, but be prepared to spend some $$
