Radiator - An uprated 2 core radiator, the original will NOT be up to the job. Uprated six blade mechanical cooling fan.

A Cooper S top bracket will be used.

Electric cooling fan - an auxiliary cooling fan will be wired up to provide extra cooling (esp. when the car is in traffic). The 2 core radiator comes in two types, one with a fan switch in the bottom and one without. Get the one with the switch will make the installation of this much easier. It's worth noting that this fan is not one of the electric fan kits (available from many mini suppliers), this one is simply a generic type fan that is about a quarter of the price. Alternatively you could source one from another car secondhand for even less, just make sure it's a thin one and blows in the right direction!
