The 6.2-liter LT4 supercharged V8 hasn’t had the greatest track record, leading to some embarrassments in the 2016 C7 Corvette Z06. Cooling issues have put the car in a pickle on more than one occasion, as experienced by professionals and owners a like.
Corvette Blogger reports on GSpeed’s attempt to solve the issue once and for all. To do so, GSpeed has taken to the Motorsports Ranch in Cresson, Texas for extreme testing to see what causes the car to enter limp mode after such a short period of time.
GSpeed states the 2016 C7 Corvette Z06 saw water temperatures of 260-degrees when it was run at Circuit of the Americas, and oil temperatures of almost 300-degrees, something they consider unacceptable. After six laps, the Corvette Z06 caved, and entered limp mode before pulling off.
Now, they’ve taken a pre-production front bumper, fitted with additional cooling slots, to add on extra radiators for the supercharger. Temperature sensors have been added throughout the engine, too, to provide critical data of fluids as the car is pushed to its limits. So far, they’ve uncovered that it’s not one particular issue, but a layer of things occurring under the hood.
It’s an ongoing discussion taking place on the Corvette Forum, which you can follow right here, and dive into the specifics of what all the data means for a future cooling fix.

Is “fitting” cooling slots like “adding” lightness? Chapman would be impressed.
Sad that GM engineers couldn’t have addressed the issue themselves!
After all this time in production and this issue is still not solved. Very, very sad indeed.
What Martin and Bob said. Should never have been for sale to the public without the problem being solved. A reputation is a very fragile thing. Mistakes like this could cost billions in lost sales. This could effect them industry wide. If you make mistakes like this on your pride and what will people think of your other vehicles.
