Cummins — HG190, HG220 Engine Manual

www.changlin.com.cn Caution: Never use water alone for coolant. Damage from corrosion can be the result of using water alone for coolant. NOTE: A50 percent mixture of antifreeze and water must be premixed before filling the system. The ability of antifreeze to remove heat from the engine is not as good as water, so pouring antifreeze into the engine first could contribute to an over heated condition before the liquids are completely mixed. Close all drain valves and fill the system. Use a mixture of 50percent water and 50 percent ethylene-glycol type antifreeze to provide freeze protection to -36°C [-34°F]. *Same capacity for charge air cooled engines. Install the pressure cap.

Operate the engine until it reaches a temperature of 80°C [176°F], and check for coolant leaks. Coolant Thermostat Replacement Preparatory Step: Drain 2 litres (2.1 U.S. Quarts) of coolant. Remove the radiator hose from the outlet connection. Remove the drive belt. 97 / 149 pages Coolant Capacity (Engine Only) Liter U.S. Quarts 10.1 6C8.3 10.5 10.1 6CT8.3* 10.5 12.3 6CTA8.2 13.0
