NUT-TRACK 5162635 - Caterpillar

Never add coolant to an overheated engine; allow the engine to cool first.Check the specific gravity of the coolant solution frequently in cold weather to ensure adequate protection.If the machine is to be stored in, or shipped to, an area with freezing temperatures the cooling system must be protected to the lowest expected outside temperature.All water is corrosive at engine operating temperature. The cooling system should be protected with a 3% to 6% concentration of cooling system conditioner at all times, regardless of the concentration of antifreeze.Excessive coolant conditioner (greater than the recommended 6% initial fill) together with concentrations of antifreeze greater than 65%, cause a mud-like deposit to form. This may result in radiator tube blockage and overheating.Do not use liquid Caterpillar cooling system conditioner with Dowtherm 209 Full-Fill coolant. Follow recommendations provided with Dowtherm 209 Full-Fill coolant.
Coolant should be drained and replaced every 2000 service hours or 1 year. However, when adding liquid Caterpillar cooling system conditioner, or equivalent, every 250 service hours as recommended, the drain period can be extended to 4000 service hours or 2 years.Clean the cooling system if it is contaminated, if the engine overheats or if foaming is observed in the radiator.Premix coolant solution to provide protection to the lowest expected outside temperature. Pure undiluted antifreeze will freeze at -23°C (-10°F).Use clean water that is low in scale forming mineral. Do not use softened water.Filling at over 20 liters (5 U.S. gallons) per minute can cause air pockets in the cooling system.After draining and refilling the cooling system, always operate the engine with the radiator cap removed until the coolant level stabilizes. Recheck the coolant level and add coolant as necessary to fill the system.The engine cooling system is protected to -28°C (-20°F) with a permanent-type antifreeze, when shipped from the factory.Operate with a thermostat in the cooling system year-round. Overheating will occur without a thermostat.Cooling System Conditioner Liquid
A 3% to 6% concentration of liquid Caterpillar cooling system conditioner, or equivalent, can be maintained by adding conditioner every 250 service hours of operation.Fuel System
Fill the fuel tank the end of each day of operation to drive out moist air and to prevent condensation.Do not fill the tank to the top. Fuel expands as it gets warm and may overflow.Do not fill the fuel filters with fuel before installing them. Contaminated fuel will cause accelerated wear to the fuel system parts.
Check the fuel level on the sight gauge.After changing the fuel filters, always prime the fuel system to remove air bubbles from the system.Drain water and sediment from any fuel storage tank weekly, and before the tank is refilled. This will prevent water or sediment being pumped from the storage tank into the machine fuel tank.Use only fuel as recommended in the "Coolant Fuel and Lubrication Specifications" section of this guide.Hydraulic System
Make-up oil added to the hydraulic tank must mix with the oil already in the system. Use only petroleum products unless the system is equipped for use with special products.If the
