OPERATING INSTRUCTIONS 6015 / RH40E Inspection and servicing
The drain valve for coolant is accessible under the engine compartment (arrow, Fig. 3-23:). Drain off the coolant with the drain hose attached to the drain valve. (arrow, Fig. 3-23:). The use of the cooling liquid draining hose is described in the " Hose line for oil and cooling liquid changes " chapter. Remove the drain hose from the valve after the oil / coolant has drained off; the valve closes automatically. Fill the required amount of cooling agent CAT ELC, Bucyrus HEX P/N 2482777, which is specially adapted to these engines, into the system by pouring it into the expansion reservoir (2, Fig. 3-21:). (see: "Refilling quantities Other" table.).
Testing the cooling liquid composition The „Engine operating instructions“ contain a detailed description of how to prepare and test the cooling liquid composition. In case of imminent frost check that the factory-adjusted anti-freeze concentration is sufficient for the expected temperatures. Check the cooling liquid in the cooling system regularly to ensure that the mixture is sufficiently concentrated to prevent corrosion under the corresponding operating conditions.
Check the filling level at indidicator (3, Fig. 3-22:). After topping up with coolant run the engine for a short time to remove air inclusions before filling the system with coolant up to the mark on indicator (3). For more information see also: "Operating and servicing instructions for the engine".
