Removal operations are carried out on a cold engine. Open the heater valve (the crane drive handle is set to the extreme right position). Unscrew the drain plugs of the engine and radiator, remove the plug of the expansion tank and drain the coolant into a container. Disconnect the coolant inlet and outlet hoses from the radiator. Disconnect the electrical wires from the electric fan and its sensor. Unscrew the nuts of the upper radiator mount and remove the bracket, tilt the radiator and remove the expansion tank hose. Take out the radiator assembly with the electric fan and disconnect the radiator casing assembly with the electric fan. If necessary, disconnect the electric fan.
Install the radiator in reverse order. After installation, fill in the coolant and check the tightness of the connections.
