The disclosure provides a filling adapter for filling vehicles with various operating materials which are fed from filling systems via connecting lines and filling adapters into circuits and containers of the vehicles. The disclosure provides a mechanical clamping element for such a filling adapter that has a lower mechanical load on the filling port than the known clamping claws or balls. The clamping element has a partially circular contour with a cross-section which, starting from a lower and flat base surface, merges upwards into two side surfaces which are arranged at right angles to the base surface and run parallel to one another, wherein the two side surfaces each merge at their end section arranged opposite the base surface into an actuating surface that runs obliquely upwards and inwards.

A method for filling a hydraulic system with a hydraulic fluid includes sealing the hydraulic system in a pressure-tight manner and recording a pressure in the sealed hydraulic system, filling or removing a predefined volume of the hydraulic fluid from the sealed hydraulic system, recording a pressure in the sealed hydraulic system after the filling or removing, calculating a volume of a total residual air in the hydraulic system depending on the pressures before and after the filling or removal of the predefined volume, calculating a final correction volume depending on the volume and a design-specified air feed of the hydraulic system, and refilling or removing the calculated final correction volume to achieve a final correct filling quantity for the hydraulic system.

A control method for an engine coolant valve includes: monitoring an engine driving condition and an engine driving environment; predicting, by a controller, degradation of an engine coolant based on the engine driving condition and the engine driving environment by a controller; changing, by the controller, an opening of an integrated flow control valve when the engine coolant is predicted to be degraded; and generating, by the controller, a coolant exchange alarm when the engine coolant is predicted to be out of a control range and degraded.

A method for exchanging coolant in a cooling system, which cooling system comprises at least one pump, an inlet conduit, an outlet conduit. The inlet conduit is connected to at least one external coolant source. The method comprises controlling said at least one pump to flow coolant in the cooling system from the at least one coolant source via the inlet conduit, through the cooling system, to the outlet conduit until the coolant in the cooling system has been at least partly exchanged. The disclosure also relates to a control unit configured to control exchange of coolant according to the method, a cooling system comprising the control unit and a vehicle or vessel comprising the cooling system.

The present invention provides a system and method for efficiently replacing the coolant in a vehicle engine and for checking the integrity of the coolant system to identify leaks.

The invention relates to an internal combustion engine comprising a combustion engine (10) and a cooling system, which has a coolant pump (40), a main cooler (38), a heating heat exchanger (36), coolant channels (28, 30) in the combustion engine (10), and a control device (20) having an actuator (26) for the closed-loop distribution of a coolant according to at least one local coolant temperature, characterised in that the control device (20) can be connected to a coolant compensation container (106) via a connection in line and, with an actuation of the actuator (26) in one direction, the control device (20): permits a coolant flow through the coolant channels (28, 30) of the combustion engine (10), and through the heating heat exchanger (36), and prevents same through the main cooler (38), and closes the connection line in a first primary position (80); releases the connection line in a second primary position (96); and also permits a coolant flow though the main cooler (38) in a third primary position (126).
