    Information contained within the McLaren 720S GT3 Technical Manual is updated regularly due to the constant development and drive to progress quality and performance of each McLaren Automotive product. The latest version of the document is available to view and download from the McLaren Customer Racing Portal.

  • Page 13: Disclaimer

    It is also the responsibility of teams to make sure that McLaren Customer Racing has up-to-date contact information for CTB and other documentation distribution.

  • Page 14: Pre And Post-Use Checks

    Return to: Exhaust V-Band Clamp 2.1.1.1 Vehicle Warm Up Values McLaren Customer Racing recommends running the car until the following temperatures are achieved. For details on achieving powertrain temperatures in a low ambient condition, please refer to: Brake and Radiator Blanking.

  • Page 15: Engine Coolant Level Check

    NOTE: Engine coolant is toxic, please exercise caution. NOTE: McLaren Customer Racing recommends that the coolant level is set prior to the engine reaching operational temperature. NOTE: Do not add any type of water wetter to the recommended coolant. The addition of a water wetter may cause a build-up, which could block the heat exchangers causing temperature increase.

  • Page 18: Brake Fluid Level Check

    NOTE: If the brake system is dismantled a brake bleed will be required. Following removal of any brake lines or ABS modulator from the car, McLaren Customer Racing recommends a full ABS bleed routine is competed using the MDS tool. Please refer to: ABS Modulator Bleed.

  • Page 19: Fuel Consumption

    Fuel Consumption Fuel consumption should typically average 0.55 0.75 L/KM for normal running (depending on driver and track characteristics). There may be some variation in this value due to the torque demand nature of the engine calibration, which will adjust certain parameters to meet the target, including, but not limited to, fuel used, throttle body opening, and ignition timing.

  • Page 20: Maximum Operating Temperatures

    For details of how to view the recommended values, please refer to: Diagnostics and VBOX. Critical Component Checks After each period of running, McLaren Customer Racing recommends that the vehicle is inspected and all critical components and bolts are torque checked to make sure components do not work loose or become damaged.
