I now have direct-replacement aluminum radiators for 1800 and 2L Spiders. These bolt right in place of the stock radiator, use the stock cooling fan and fan switch. These radiators only weigh 7lbs!! $189 plus shipping

I think aluminum is around 1/3 the weight of copper, but I saw online somewhere that an aluminum rad will be about 30% to 40% lighter. There must be more metal in an aluminum rad.
Thickness too? With the diesel conversion I have less than 1/2 inch between the oem radiator and the water pump shaft and I know that eventually I am going to need to replace the radiator.
Will it help the stock motors run cooler during hot weather using the stock fan? If so, how much?
