Plymouth Duster Cooling Suggestion

With any AL radiator, use a very good coolant and change it every 2-3 years. The electrolysis is such that the AL radiator is the sacrificial metal, not the iron block. With a brass radiator, the iron block is sacrificial and so brass rads lasted a long time. Any rad like the Champions can be worse for eletrolysis because they are solid AL, and the rad connects directly to the steel frame. Make sure you have a couple of good ground straps with very clean connections to ground the block to the chassis to reduce the corrosion in any AL rad.
