Well, that was interesting.. A stock rad weighs 4.1kg, and the alloy one is lighter at 3.3kg. But while the stock one only takes 1.6kg water, the alloy takes 2.4.
So they both weigh 5.7kg when full, but you can see how the alloy can disperse more heat, especially as its larger, 20mm wider and deeper in the core.
I bolted the driver's side onto the stock mounts, the lower one needs a new hole and a spacer. The passenger's side needed a plate, a strip of 1mm galv about 70mm wide, to bolt the wider frame on.
The same fan is on, although using the given holes on the other side, and I need to make another brace for the floating edge.
The temp gauge runs in the same place, so a stock radiator can handle a 4AGE generally, but it doesn't have anyhing left in reserve for hot work. I put a thermometer in the top of the rad and let it idle up to warm.
Well, vented discs & rad done, but I'm sure there are still things on my project list...
