I've decided to get an aluminum rad. Now the dilemma is do i also get the electric fan(s) and controller or just move to the aluminum rad and use the stock shroud and clutch fan. Is there a downside to only going for the rad by itself? But i keep thinking...if you're getting one you must get the other. What's been your experience..if i just get the alum. Rad will that make a huge difference or is it viewed that I'm only delaying the inevitable. I should add that i face a lot of stop and go traffic and sitting a lights.
