A 20/80% or 30/70% Coolant-Antifreeze/water will provide more cooling than a 50/50 mix. But if you need to significantly more cooling a larger aluminum radiator, like one from DeWitt's would be the way to go.Anybody here used Dexcool in their Z06? Trying to keep temps down during track days...THX!
Hi Man, You should Put 50% Dexcool (Orange Color for ex. 2005-2006-2007... Z06) + 50% Pure Water and fill it to the Half of the Reservoir till the Max. Mark Level on Cold and exactly fill it to the mark. Just Mix them inside a gallon perfectly before you add them to the reservoir.Anybody here used Dexcool in their Z06?

Please share the temp & brand thermostat you use. I tested about a half dozen different brand "180*" thermostats and found they don't begin to open until about 192*.
