Radiaror / Engine cooling, best fan set up

[wbute]

The fan needs to suit the driving you do to. If it's all around town or burn outs etc then you need bigger fan capacity. The fan will nearly never cut in on the highway. As Taily said, the hotter it runs the better. Make sure the water pump is working properly too.
Are the copper core radiators hard to get or why are people moving to alloy ones?

James you can buy a cheap alloy radiator 1/3 of the price of a copper core one thats why
