Greetings to one and all. Was curious to see if anyone else had a v8 Hilux and what sort of radiator they had in it. I have a 79 RN46 model with a Holden 308, standard 4 speed with a LN46 radiator and 16 inch thermo fan. Only problem is it gets hot when not running at speed, arouns 40 kph or under even with the fan. Was looking for alternatives to keep this one cool, as its 4WD capabilities are nil. It runs straight gas, goes like a dream on the road now it has a 3.58 centre in the back from 4.875, front diff not yet changed over. When time permits!!

It really depends on the diff housing. I have an RN46 with G142 diffs (4.875 gears) and apparently nothing will fit it, in terms of changing gears with that centre. I was able to bolt a KUN26 centre into the rear housing (3.58 ratio) with minimal fuss, just the usual pulling of brakes, axles and new bearings while they're out. You can buy similar gears from Mark 4WD but you will need to change the diff centre regardless, any diff centre with gears 4.5 or higher should be OK to do this with.
