We have assembled the Best C7 Z06 Cooling Mods for
2015-2019 Z06 Corvettes on the planet!
Starting at the top, we guide you to prioritize your first upgrades to be on the cooling system. Especially if you have 2015-16 models. The 2017 model corvette implemented factory solutions to mitigate the overheating risk.
Why you ask?
Corvette engineers admit to missing the mark for the cooling needs on early Z06 Corvettes. They claim that adding performance upgrades compounded the issue of inadequate cooling, so we suggest cooling upgrades first.
The remaining items in all sections are the Best of the Best C7 Corvette Upgrades in each particular section.
C7 Corvette Q&A Performance Upgrade Comments
C7 Z06 Performance Upgrades | By Chris Trautman
So, a little info you may or may not know, some C7 Z06 Corvettes have cooling issues when used in high power demand applications. Most owners will not experience this unless the car's cooling system gets massively heat soaked with hot weather and track-based high-speed/load events.
The C7 Z06 was engineered with a "pro driver @ 86 degrees" design standard for all performance development. The philosophy had proven to work well for GM for many years. After a few years, GM realized that owners on tracks in southern warmer climates had issues overheating and cars going into reduced power modes.
The first generation of Z06 Corvettes (2015-2016) had the majority of the issues. 2017+ GM solved the cooling problems, and many companies have come to the rescue with Cooling Upgrades for the Corvettes without the extra cooling or those that require additional upgrades.
We cover the details of all the fixes below..........
1. Option - C7 Z06 Radiator Performance Upgrade..........
The number one thing GM had to do to fix the cooling issue was to increase the size of the radiator on later generations of the C7 Z06 Corvette. More volume equals better cooling efficiency. For the rest of us, early Z06 owners (our selves included) require us to upgrade on our own. The first radiator in this section has a higher price point and may work better in extreme situations.
2. Option - C7 Z06 LG Motorsports Radiator Upgrade........
LG Motorsports makes some of the best performance parts you will find for your C7 Corvette and they were one of the first to offer cooling upgrades for the C7 Z06.
3. C7 Z06 Intercooler Radiator Upgrade..........
This little radiator cools the coolant in the Supercharger air to water intercooler system. For maximum performance we suggest upgrading to increase the cooling capacity of your intercooler and thus decreasing the intake air temperature which increases the air density and thus increases the horsepower potential of what your engine can produce.
The C7 Corvette Z06 has a dry sump oiling system. The oil is scavenged from the oil pan and returned to the oil tank where the majority of the oil is kept. The tank is located where you fill your oil on the right hand side of the car.
The problem with this location is both scavenge and oil pump return lines run right past the Catalytic converter near the right hand exhaust system.
The converter reaches temperatures over 1200 degrees and sits about 1 inch from these critical oil lines.
The best way to combat the emissive directive heat soak is through space age heat insulation systems such as the DEI Oil Cooler Heat Shroud.
Its cheap insurance at twice the price!
The Oil Cooler is located on the opposite side of the engine compared to the oil lines. The same problem exists here, except the oil cooler is right next to the catalytic converter, wait what?
Why GM didn't include this heat protection stock we don't know, regardless now is the time to upgrade!
As you can see in the picture below the oil cooler is directly located behind the catalytic converter (seen here wrapped in Design Engineering 010069 Catalytic Converter Titanium Heat Shield for C7 Corvette (2015-2016)
The wrapped catalytic converter deflects the heat transmitted from the 1200+ degree converter away from the Oil Cooler. This allows the Oil Cooler to do its job more efficiently!
Cool Features (Pun intended)!

Established in 2008 by Chris Trautman, Corvette Web Central quickly grew into one of the top leading Corvette enthusiast websites globally.
"This website is a passion of mine just as much as being a Corvette owner," says Chris. He was frustrated trying to find information on the internet about Corvettes which was was not biased or influenced somehow.
He has owned three Corvettes over the last twenty years and does not plan to stop owning one anytime soon.
