BUCKET & ADJUSTER GP 3476852 - Caterpillar

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.
1. Release the pressure in the cooling system by slowly loosening the fill cap on the radiator. Drain the coolant from the cooling system by placing a drain hose through the hole in the back of the bumper, attaching the hose to the drain valve fitting and opening the drain valve. Drain the coolant from the engine and cooling system in a suitable container for storage or disposal. Refer to the "Operation & Maintenance Manual" for cooling system capacities. Drain the engine coolant to a level below the top hose. 2. Loosen the two hose clamps and remove top coolant hose (1).3. Disconnect two fuel hose assemblies (2). Plug the hose fittings in order to prevent dirt and debris to enter the fuel system.4. Shut off the main fuel valve and disconnect hose assembly (4).5. Disconnect wire connector (6).6. Remove bolts (3) from pump and filter assembly (5). Remove pump and filter assembly (5) from the side of the fuel tank.7. Remove bolt (7) and the clip. 8.
