Cooling System
Never add coolant to an overheated engine; allow engine to cool first.Measure specific gravity of antifreeze solution frequently in cold weather to assure adequate protection.When permanent antifreeze and water solutions are used in the cooling system, the solution should be drained and replaced EVERY 2000 SERVICE HOURS OR 1 YEAR.When additions of inhibitor are made EVERY 500 SERVICE HOURS OR 3 MONTHS, cooling system drain and refill periods can be extended to 4000 service hours or 2 years.The cooling system should contain a 3% concentration of inhibitor at all times, regardless of concentration of antifreeze.If machine is to be shipped to, or stored in, an area with below freezing temperatures, the cooling system must either be protected to the lowest expected ambient temperature, or drained completely.
The engine cooling system is protected to -20°F (-29°C), with permanent-type antifreeze, when shipped from the factory. Pure undiluted antifreeze will freeze at -10°F (-23°C).Use clean water that is low in scale forming minerals - not softened water. Add Caterpillar Cooling System Inhibitor, or equivalent. Follow directions on the container.When draining and refilling the cooling system, always measure the coolant level when the engine reaches normal operating temperature.Filling the cooling system at over 5 gpm (19 liters/min) rate can cause air pockets in the cooling system.When measuring the coolant level, inspect the filler cap gasket. Replace the gasket if it is damaged.Premix an antifreeze solution to provide protection to the cooling system to the lowest expected ambient temperature.Operate with a thermostat in the cooling system all year-round. Cooling system problems can arise without a thermostat.Hydraulic System
Make-up hydraulic fluid must mix with fluid in the tank. Use only petroleum products unless machine is equipped for use with special products.Water or air in the hydraulic system will cause pump failure.
If hydraulic oil is cloudy, water or air is entering the system. Purge and refill the system, and tighten hydraulic suction line clamps and flanges.Contact your Caterpillar dealer for correct purging instructions.Fuel System
Fill fuel tanks at the end of each day of operation to drive out moisture laden air and to prevent condensation.Measure fuel level with the dipstick in filler opening.Water and sediment should be drained from the machine's fuel tank at the start of each shift, or after the fuel tank has been filled and allowed to stand for 5 to 10 minutes.Drain moisture and sediment from the machine fuel tanks as often as required by prevailing conditions.Drain water and sediment from the main fuel storage tank weekly, and before the tank is refilled, to help prevent water and sediment from being pumped from the storage tank into the machine fuel tank.If the engine fuel system is equipped with a water separator, drain water from the separator daily before starting engine. Always drain water from the separator before it becomes one-half full. Frequent draining may be necessary in areas of high humidity, or when fuel supply is contaminated with water.After changing fuel filter, always bleed the fuel system to remove air bubbles from the
