Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the machine. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to "Tools And Shop Products Guide", NENG2500 for tools and supplies suitable to collect and contain fluids in Caterpillar machines. Dispose fluids according to local regulations and mandates.
At operating temperature, the engine coolant is hot and under pressure. Steam can cause personal injury. Drain the coolant only after the engine has been stopped and the fill cap is cool enough to touch with your bare hand. Remove the fill cap from the radiator slowly to relieve pressure. Cooling system conditioner contains alkali. Avoid contact with the skin and eyes to avoid personal injury.
1. Position a suitable container under the radiator. Loosen the radiator cap from the tank assembly. Remove the drain plug from the plug adapter, and drain the radiator below the level of the expansion tank assembly. The capacity of the cooling system is 142 L (37 U.S. gal). For more information, refer to the topic "Drain And Refill Radiator" in this manual. 2. Mark and identify two wire harnesses (1) and (3) for installation purposes. Disconnect two wire harness (1) and (3) from relay panel (2). 3. Mark and identify two hoses (7) and (8) for installation purposes. Put a suitable container under two hoses (7) and (8) to contain the coolant for storage or disposal. Loosen two clamps (5) and (6). Disconnect two hoses (7) and (8) from tank assembly (4). 4. Loosen clamp (9) and disconnect hose (10) from tank assembly (4). 5. Remove two bolts (11) and the washers from grate assembly (12). 6. Remove 20 bolts (13) and the washers that holds the front hood assembly to engine enclosure tube assemblies (14). 7. Remove bolt (16) and the washer from front hood assembly (15). 8. Position a suitable lifting device on front hood assembly (15) and grate assembly (12) as shown. Secure the lifting device to a hoist. Remove front hood assembly (15) and grate assembly (12) as a unit, from the engine enclosure. The weight of front hood assembly (12) and grate assembly (15) as a unit, is 204 Kg (450 lb). 9. Remove right hand door assembly (17) from right hand door assembly (18). 10. Remove bolt (20), the washer, and right hand door assembly (19) from the engine enclosure. 11.
