    Abstract: A coolant draining tool for draining a coolant from an electrical storage system, ESS, of a heavy-duty vehicle, wherein the coolant draining tool is of elongated shape and includes an internal tubular channel for guiding a flow of coolant in a discharge direction, the coolant draining tool including an externally threaded portion which encloses the tubular channel at a distal first end of the coolant draining tool, wherein a valve engagement member is arranged centered in the tubular channel at the first end of the coolant draining tool, the valve engagement member being arranged to engage a spring-loaded valve of an ESS connector to bias the valve into an open position.

    Abstract: A cooling system for an engine includes a coolant tank, a heat exchanger, and a drain valve. The coolant tank holds a fluid coolant and is coupled with a tank conduit through which the coolant flows from or to the coolant tank. The heat exchanger is fluidly coupled with a supply conduit. The drain valve is fluidly coupled with the coolant tank by the tank conduit and with the supply conduit. The drain valve is fluidly coupled with a drain conduit that directs the coolant out of the cooling system and alternates between a closed position and an open position. The drain valve prevents the coolant from flowing out of the cooling system through the drain conduit when in the closed position and permits the coolant to flow from the heat exchanger and out of the cooling system through the drain conduit when in the open position.

    Abstract translation: 用于发动机的冷却系统包括冷却剂箱，热交换器和排水阀。 冷却剂罐保持流体冷却剂并且与罐管道联接，冷却剂从冷却剂管道流过冷却剂罐。 热交换器与供应管道流体耦合。 排水阀通过油箱管道和供油管路与冷却剂箱流体耦合。 排水阀与排水管流体连接，排水管将冷却剂引导出冷却系统，并在关闭位置和打开位置之间交替。 当处于关闭位置时，排水阀防止冷却剂从冷却系统流出排出管道，并且当处于打开位置时允许冷却剂从热交换器流出并通过排水管道流出冷却系统。
