I believe you want to reprogram the fans to come on earlier, like 195 ish. For high level racing, I would run two separate coolant packages. Run straight distilled water with a surfactant like Wetter Water. When you are done racing, drain in out and save that mix. Re-install the factory 50/50. I don't think it would help much but you could also go with a lower thermostat to start cooling earlier. Those items shouldn't void any warranty.

They must have been,i did put in a 180 therm from ligenfelter and 30/70coolant to water ratio,the car runs in cooler mornings around 180 to 185,in 97 degree heat at 60 mph it runs around 192,in traffic at 97 it stays under 200, I have not been to a road track with this set up yet,i do not have a tune or a fan tune,i have a fasterproms intercooler tank and I removed the ducting on top of the radiator,also removed the rubber by the winshield.i would not go any cooler on the therm when it is cold outside the car will not be hot enough to burn all the condensation and contaminants.

2 hours very simple direct bolt in ,there are two spring loaded plastic pieces on top of the radiator that hold the a/c condenser just push in and lift the condenser,it slides into 4 slots on the dewitts radiator,refill let idle with open cap and fill as needed to get all the air out,let it run awhile with cap open it will not get to hot and overflow.

Did you have to remove the front fascia that covers the bumper or can you remove it from the engine compartment ?

Default Still trying to get info

it seems to me on the web site
Dewitt has one radiator for the C7
The never tslk sbout for the ZO6

Clearly the stingray has one type of OEM radiator and the z51 and ZO6
share a bigger one.

One vender us ckearly seeking the same dewitt in the stingray section snd the same one in the zo6 section and another says it will not eirk in zo6

So my question is there a dewitt radiator for ZO6 C7 ie i dont want to put a stingray upgrade into the z06 and end up same as OEM

Venders and Dewitt are not responding to questions by email!

To my understanding, the radiators are the same. The only difference someone pointed out was the drain was on the opposite side for the Z06

Yeah.
The ZO6 and Base car both have a single pass, single core, chevy cruze grade radiator.

Dewitts is double core, and double pass, with a larger capacity.

I call DeWitt last week, the sales person said they make only one radiator for the C7, regardless of Base , Z06, M7 or A8 (A8 does not have cooler lines going in to radiator)

Um.....not to be a jerk.....

I understand Toms comment to mean the OEM rads are one style for base Stingray and second style for Z51/Z06. And the only difference is the placement of the drain plug.

What's not clear?
