Stick with a copper brass one mate...
It is a 10 minute job to take out and have a good look at....
All depends on the load you put on your rig moderate to heavy load a upgraded radiator is basically a must and I triple core copper brassy i think works the best but you do pay for them but if you don't load her up a rad service/ flush and a check with a cheap temp gun from super cheap is all you need replace the thermostat and cap while ur in there
Whats an average cost for an upgraded copper rad?

Over here in NZ it costs around $550-700 to get a copper radiator whereas an alloy is around $300 and an aluminium about $300-400
Not really sure what metal is used in making the alloy but this is one that is listed on trade me here in NZ

Also can someone tell me if there is a big advantage to be had by getting a 3 row core over a 2 row?
As a comparison for you, I went with the Terrain Tamer heavy duty aluminium, has made a difference to keeping temps down, but a lot more pricy, around $1,000
Good to know, not that it gets hot enough in Southland to bother the factory radiator.
