HD Cooling Systems, 2015-19 Corvette Z06

The “Level 1” HD Cooling System focuses on keeping engine coolant temperatures under control and improving performance of the supercharger’s intercooler system. Oil temperatures are inherently improved, as this system is cooled by the engine’s coolant circuit. This system is ideal for spirited road driving, for autocross or for high speed open road racing events.

HD Cooling System – Level 1 features:
  > Carbon fiber grille surround with laser-cut Callaway grille insert
  > High flow rate intercooler pump for enhanced heat transfer; flows 20% more than SC757 pump and 35% more than stock Z06 pump
  > High flow rate thermostat assembly; CNC-machined housing, anodized in Callaway Blue, with new high flow thermostat
  > Increased intercooler system capacity

The “Level 2” HD Cooling System contains all Level 1 components and adds an air-to-oil cooling system, a carbon fiber aerodynamic splitter and full undertray. The addition of the standalone air-to-oil cooler integrated into the splitter/undertray, in conjunction with the removal of the OE water-to-oil heat exchanger, provides a substantial decrease in engine oil temperature. Plus, the new splitter and undertray provide considerable aerodynamic improvement, shifting balance to reduce understeer.

HD Cooling System – Level 2 includes:
   Level 1 components, plus –
  > Carbon fiber splitter; works with Corvette Stage 2 and Stage 3 aero extensions
  > Carbon fiber front undertray with integrated brake cooling channels, extending rearward to front subframe
  > Air-to-oil heat exchanger integrated between new splitter and undertray, replacing OEM oil-to-water heat exchanger
  > Lightweight High-Temp polymer-braided -10AN oil cooler lines with CNC-machined thermostatically controlled adapter housing

The HD Cooling Grille is also offered separately, with integrated ducts providing cooling air to front brakes and cool air to the engine intake.

HD Cooling Grille – features:
  > Carbon fiber grille surround with laser-cut Callaway insert
  > Integrated ducts direct cooling air to front brakes
  > Cold air duct feeds fresh, ambient air to engine intake
  > Installed exclusively at Callaway facilities
