Note: Nothing in this standard supercedes applicable laws and regulations.

Note: In the event of conflict between the English and domestic language, the English language shall take precedence.

Purpose. To determine if the total coolant flow, flow to the radiator, flow to the heater, flow balance in V-engines, and flow in any other branch of a cooling circuit, meets the design intent under various thermostat opening conditions. To provide hydraulic restriction (pressure drop vs. flow characteristics) data for cooling system modeling and to provide model validation. To ensure surge tank function under dynamic conditions, such as maximum engine speed. To determine the necessity for a 2^nd degassing line.

Applicability. All liquid cooled engines.

Remarks. This is a bench coolant flow test procedure used for coolant system development.
