It's been three months since our loaner Z06 last bellowed throughout the shop, but our ears are still ringing. The C6 is the very definition (more like DEAFinition) of the American sports coupe. Boisterous doesn't even begin to describe our loaner Corvette. By now, though, we all know how hot these cars are, both figuratively and literally. We're finally at the point where we can test and see just how much of that actual heat we can remove with our new aluminum radiator.

Ice Packs

Before we could berate your senses with the full-frontal assault that is the Z06, we had some shop upgrades to fit in. Specifically, we had to make sure that our Dynapack system was up to the task of challenging the ferocious LS7.

We all have that one friend that just can't seem to make up their mind. Indecision isn't just a bad habit for them, it's a way of life. At any minute you're a shrug or an "I don't care" away from utter frustration. I have to level with you folks, I am that person. Which makes it less weird to say that I can identify with the C6. Not so much to sleek body lines and unbridled athleticism, definitely neither of those. It's more so the fact that Chevy nor I can seem to make a lasting decision on anything.

Where deciding on a place to eat might be an example of my struggle with indecision, Chevy's dilemma comes more in the cooling department for their flagship sports car. If you take a look back at our last

One would think that after over 50 years of being the pinnacle of American performance some extra thought would have been put into the cooling system. That's not the American way, though. Automotive radiators have vastly improved since 1953, and when it came time for the C5's successor, it's almost as if Chevy was more interested in equipping the largest V8 possible rather than overhauling the cooling system.

On top of seemingly glossing over the C6's coolant heat exchanger, Chevy couldn't decide which radiator to equip in their flagship sports car. Over this Corvette's tenure we noted that there were 5 different radiators designed for the C6, each one slightly varied from the other.

We noted that there were two different core thicknesses, and about 4 different end tank

When you look back on America's history in the realm of speed, it seems that we're only known for one thing"straight-line speed. Our obsession with muscle cars has left the impression on the rest of the world that we here in the US are a little timid around corners. Anyone who knows anything, though, can always name one American car that can take that beeline grunt around the hairpins. The Corvette.

Chevrolet has been fixated since 1953 on being able to pilot one of their big crate motors safely around the bends. Using sleek body lines to achieve a slippery aerodynamic profile, combined with lightweight materials and stiff chassis components, the Corvette has evolved over the years from a nimble sports car to a serious contender against the best of Germany and Italy.
