There is much debate over whether a copper or an aluminum radiator will cool better. There are pros and cons to each material. It has been scientifically proven that copper actually transfers heat better than aluminum. But it's more of an personal preference.
1. Aluminum: Chances are, your classic didn’t come from the factory with an aluminum radiator. But an aluminum radiator built specifically for your unique vehicle is always an option. Aluminum requires less physical space for your radiator to do its job and it weighs much less than its stock copper/brass counterpart. So, if space and weight
I wanted to increase cooling efficiency and so had a mechanic install a Maradyne, 16″ fan. Wiring harness at 195 deg. Mechanic install sender into outlet hose from radiator w/ “T” adapter. Engine got hotter than ever. I researched and found that the sensor should be mounted on the inlet to the radiator from the engine cooling manifold.
Both copper and aluminum, however, have advantages. Copper's heat conductivity is far superior to that of aluminum. Copper radiators are also easier to repair. Aluminium, on the other hand, is much lighter and stronger than copper. Those who are more concerned with appearance prefer aluminum that can be polished to a mirror-like finish. It had a raised section that I thought would have been cut out on big block cars, so I cut it out myself. I think that this is the section that Kevin was refering to. I hope this helps. I also suggest 4 core, although I will be replacing mine with a wide 2 core Be-Cool aluminum radiator this winter. -----1970 Chevelle SS Clone 502-580HP 1-2 row is ideal for stock standard vehicles and exact replacement requirements. 3-4 rows are best for high horsepower, performance or off-roading vehicles as well as trucks. If you have more questions, speak to a cooling specialist at Natrad. There are 50 Natrad workshops nationwide who can provide detailed advice on the best options suited to shiNyu6.
