Assembly line covering the complete engine cooling circuit.
Groups the radiator, pump, swirl pot, catch can, cap, fan, shroud, ducts and lines. Design Philosophies and Processes: Inherited from the Cooling, Powertrain subsystem design process: 1. Define measured heat rejection from previous-year endurance data. 2. Iterate core parameters in the MATLAB NTU-epsilon analysis until the target is beaten with margin, at the stated assumptions: steady state, single-phase water, constant air mass flow from CFD at 32 mph average endurance speed, 105 C water inlet, 27 C air inlet, constant fluid properties. 3. Give the core geometry to Aerodynamics for duct, shroud and radiator angle design; take back the achieved mass airflow. 4. Lay out the water loop: pump at the lowest point, swirl pot cap at the highest, bleed valve on the top tank, temperature bungs at inlet and outlet. 5. Validate on a mock endurance with inlet and outlet thermistors and back-calculate heat rejection.
Fault Vault, 2026-06-07, CR26I, Operational Errors, Performance Failure. Improper bleeding left excess air in the cooling system. The pump duty cycle was too high for air to be released and the pump's PWM control did not enable until the engine was on. Recorded fix: change M1 Build to allow cooling bleed tests, or vacuum fill the system.
