Purpose. To determine if the total coolant flow, flow to the radiator, flow to the heater, and flow balance in engines, meets the design intent under various thermostat opening conditions. To provide additional data for 1D system modeling and the model validation. In particular, the pressure-drop vs. flow characteristics for system components is required. To ensure surge tank function under dynamic conditions, such as maximum engine speed. To determine the necessity for a second degassing line.

Foreword. This is a vehicle coolant flow test procedure used for coolant system development.

Applicability. All liquid cooled engines.
