At operating temperature, the engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot water or steam. Any contact can cause severe burns. Look at the sight gauge to check the coolant level. The coolant level should be in the green range. If necessary, remove the fill cap only after the engine has been stopped and the cap is cool enough to remove with your bare hand. Remove the cooling system fill cap slowly to relieve pressure. Cooling system condition contains alkali that can cause personal injury. Avoid contact with the skin and eyes and do not drink. Allow cooling system components to cool before draining.
Put identification on all lines, hoses, wires and tubes for installation purposes. Cap and plug all lines, hoses and tubes to prevent foreign material from entering the system. Drain all fluids in a suitable container for storage or disposal.1. Remove the front bottom guard. Drain the coolant from the radiator in a suitable container. 2. Remove bolts (1) and remove two sections of fan guard (2). 3. Loosen clamp (3) and disconnect upper radiator hose (4) from the radiator. 4. Loosen clamp (7) and disconnect lower radiator hose (6) from the radiator.5. Remove power train oil cooler hose assemblies (5) and (9).6. Disconnect wire harness connector (8). 7. Attach suitable lifting straps to the radiator guard assembly as shown.8. Remove radiator guard assembly mounting bolts (10) from underneath the machine.9. Remove the radiator and the radiator guard assembly from the machine. The weight of the radiator is 281 kg (620 lb). Install in the reverse order.10. Install the front bottom guard.End By:a. install hood Refer to the Operation & Maintenance Manual for all fluid capacities and the proper filling procedures.Disassemble & Assemble Radiator
