Fuel and the Effect from Cold Weather
The two types of diesel fuel recommended for your engine are grades No. 1 and No. 2. Although No. 2 diesel fuel is the most commonly used fuel, No. 1 diesel fuel or a blend of No. 1 and No. 2, is the fuel that is best suited for cold weather operation.During cold weather operation, it may be necessary for you to use No. 2 diesel fuel since quantities of No. 1 diesel fuel are limited and generally are only available in certain areas.There are three major differences between No. 1 and No. 2 diesel fuel.* No. 1 diesel fuel has a lower cloud point. The cloud point is the temperature at which a cloud or haze of wax crystals will begin to form in the fuel and cause fuel filters to plug.* No. 1 diesel fuel has a lower pour point. The pour point is the temperature which diesel fuel will begin to thicken and be more resistant to flow through fuel pumps and lines.* No. 1 diesel fuel has a lower BTU (kJ) (heat content) rating per unit volume of fuel than the average No. 2 diesel fuel. When using No. 1 diesel fuel, you may notice a drop in power and fuel efficiency, but should not experience any other operating effects. Before troubleshooting for low power or poor performance in winter months, check the type of fuel being used.Be aware of these fuel values when purchasing your diesel fuel and anticipate the average outside (ambient) temperature for the area your engine will be operating. Engines fueled in one climate may not operate satisfactorily if moved to another because of problems that result from cold weather.Attachments are available from your Caterpillar dealer to minimize cold weather starting and operation problems. The use of starting aids, engine oil pan heaters, engine coolant heaters, fuel heaters and fuel line insulation also provide a means of minimizing starting and fuel problems in cold weather when No. 2 diesel fuel is used.For further information on cylinder block (coolant) heaters, contact your Caterpillar dealer. The average No. 1 diesel fuel has a lower kJ (BTU) (heat content) rating per unit volume of fuel than the average No. 2 diesel fuel. When using No. 1 diesel fuel, you may notice a drop in power and fuel efficiency, but should not experience any other operating effects.Fuel Related Components in Cold Weather
Fuel Tanks
Store the fuel outside to allow water (condensation) to freeze after separation from the fuel and to indicate any immediate temperature affect on the fuel. Fuel tanks should contain some provision for draining water and sediment from the bottom of the tanks. Some fuel tanks use supply pipes that allow water and sediment to settle below the end of the fuel supply pipe. This water and sediment should be drained at every oil change.Some fuel tanks use supply lines that take fuel directly from the bottom of the tank. If equipped with this system, regular maintenance of the fuel system filter(s) is important.Fuel Heaters
Only thermostatically controlled or self-regulating fuel heaters should be used with this engine.
Heat exchanger-type fuel heaters should have a bypass provision to prevent excessive heating of the fuel in warm weather operation. This overheating of the fuel will cause a loss of engine power.Fuel heaters prevent plugging of the fuel filters in cold weather due to waxing. Non-thermostatically controlled fuel heaters can heat the fuel in excess of 65°C (150°F). High fuel temperatures reduce engine performance and power availability.A fuel heater should be installed so that the fuel is heated before it enters the first (primary) fuel filter. Select a fuel heater that is mechanically simple, yet adequate for the application. The fuel heater should also prevent overheating of the fuel. Choose a fuel heater with as large a heating surface as practical. Small heaters can be too hot in their limited surface area.Disconnect or deactivate the fuel heater in warm weather. A loss of engine power can occur if the fuel supply temperature exceeds 37°C (100°F).For further information on fuel heaters, contact Caterpillar.Fuel Filters
The use of an auxiliary primary fuel filter and/or water separator is recommended between the fuel tank and the engine mounted fuel filter. The particle size rating (micron) and location of the primary fuel filter are important in cold weather operation. The primary fuel filter and its fuel supply line are the most common components affected by cold fuel.The particle size rating (micron) of the primary fuel filter should only be fine (low) enough to protect the fuel transfer pump. A very fine (low micron rating) primary filter, can be more easily plugged by wax in cold weather. A primary filter, with a particle size rating (micron) as fine as a secondary filter, can cause plugging due to fuel waxing. The best location for the primary fuel filter is in the engine compartment, where it will benefit from the radiant heat of the engine. A filter location exposed to wind can be a persistent problem in cold weather.Refer to the Parts Manual for this engine to determine the part numbers required for the primary fuel filter.Engine Lubrication Oil Viscosity
Proper engine oil viscosity is essential to ensure engine starting at cold ambient temperatures. Refer to the Lubricant Viscosity chart in this Manual for recommended oil viscosities to use at various operating temperature ranges.Engine Coolant Modification
Ensure that the coolant/antifreeze concentration will provide adequate freeze protection. Refer to the Antifreeze Concentration chart in the Cooling System Specifications section in this Manual for proper concentration/protection.Refer to the vessel or OEM Owner Manual for information regarding coolant heater operation and maintenance.Batteries
Install batteries to provide 1500 cold cranking amps (CCA) if engine will not start and operate in conditions below 0°C (32°F).Maintain proper battery electrolyte level. Keep all batteries fully charged (to a corrected specific gravity of 1.250 or above) and warm. Heating of the battery compartment or storage in a warm location will preserve a minimum of 70 percent of the cranking power. The
