Project C7 Corvette Stingray, Keeping It Track Cool With CSF

Now the radiator can be slipped into place.

The AC condenser is bolted to the front of the radiator first.

Now the radiator can be bolted back to the core support.

The fan and fan shroud is installed next.

The bottom of the radiator to hood scoop air guide had to be slightly modified to accommodate the thicker radiator core.

This notch had to be cut out.  It literally took just a few minutes.  The side of the mounting flange below the tabs had to be narrowed slightly as well.  This was super easy to do.


  1. It’s interesting that the radiator guide only needs to cover 1/3 of the radiator.

    I can guess at a few of the factors that go into the consideration of this choice, but coming up with the idea of partial coverage is the stroke of genius. Deciding on how much to cover must be an interesting exercise too.

    1. My opinion is that GM wanted to have some airflow through the engine compartment to keep the cats from cooking off stuff in there, so some air is vented out the hood, the rest flows through the engine compartment, keeps the cats cool and then exits out the fender vents.

      1. And it also prevents any problems with driving or parking your car in heavy rain because the water does not touch any engine components.

  2. what temps were you guys hitting with the aux rad installed before switching to the CSF? You say C7’s hit 220-230 at the track, but nothing about specifically this car before and after…

    also, limp mode is 260. at 230 they start pulling timing and reducing power.

  3. You provided pictures and instructions for installing the CSF Radiator. But you failed to provide information on how to order it and l have no idea on how much it may cost to obtain it.
