Cold Weather Hints
* If the engine is started for any reason, operate the engine until a minimum operating temperature of 71°C (160°F) is achieved. This will help to prevent the valves from sticking due to unburned fuel.* The cooling system and the lubrication system of the engine do not lose heat immediately upon shutdown of the engine. This means that an engine can be shut down for a few hours and still start readily. If the engine is shut down for at least eight hours, the engine should be considered cooled to the outside temperature.* Utilize the correct lubricant or fluid for each engine compartment before cold weather begins.* Inspect all of the rubber parts (hoses, fan belts, etc) weekly.* Inspect all of the electrical wiring and connections for any frays or damaged insulation. Keep all of the batteries fully charged and warm. * To prevent condensation on exposed fuel tank walls, fill the fuel tank when the engine will be shut off for eight hours or more. Keep the fuel tank as full as possible.* Inspect the air cleaners and the air inlet daily, or as necessary, when working in snow.
Do not store alcohol or starting fluids in the operator's compartment. They are highly flammable and toxic.
DO NOT USE ETHER (starting fluids) unless specifically instructed to do so. This diesel engine is equipped with an electric air inlet heater system to aid cold weather starting and reduce white smoke. Do not spray ether into the air inlet. It will contact the heater elements. Use starting fluid ONLY if the vehicle is equipped with the optional automatic ether injection system or immediate engine damage and personal injury may result.
* Inject starting fluid only when the engine is cranking.* Air system dryers may be effective in reducing condensation and ice formation in air systems.* Alcohol injection may prevent moisture from freezing the air compressor regulator and other components of the air system.* For jump starting with cables in cold weather, refer to the topic in this manual.Fuel Recommendations for Cold Weather
The three types of diesel fuel available for your vehicle engine are typically grades No. 1, No.2 or a blend of No. 1 and No.2.There are three major differences between No. 1 and No.2 diesel fu fuel. No. 1 diesel fuel has a lower cloud point, a lower pour point and has a lower kJ (Btu) (heat content) rating than No.2 diesel fuel. The kJ (Btu) rating indicates power, therefore No. 1 grade fuel will provide less power and fuel economy, but is less likely to plug the fuel filters and flows better through the fuel system. Keep in mind that No. 1 grade fuel or fuel blends will not provide as much power as No.2 grade fuel. A difference may be noticed.Be aware of these fuel grades when purchasing your diesel fuel. Plan fuel purchases for cases of driving from warm climates into cold climates. Vehicles that are fueled in one climate may not operate satisfactorily when driven to another climate. Before troubleshooting for low power or poor performance in winter months, check the type of fuel or blend of fuel that is being used.No.2 diesel may be blended with No. 1 or kerosene in the following proportions to achieve lower temperature flow capabilities.

Fuel Heaters
When the use of unblended No.2 diesel in the winter cannot be avoided, a thermostatically controlled or self regulating fuel heater can be installed. Fuel heaters are not effective for cold starts unless they are powered by an external source (i.e. AC current). Select a fuel heater that is mechanically simple, yet adequate for the application. Choose a fuel heater with as large a heating surface as practical. Small fuel heaters can be too hot for their limited surface area. Heat exchanger type fuel heaters should have a bypass provision to prevent excessive heating of the fuel in warm weather operation. The excessive heating of the fuel will cause a loss of engine power. Consult your Caterpillar dealer for information on the fuel heaters that are available for your engine.Disconnect or deactivate the fuel heater in warm weather in order to prevent excessive heating of fuel and possible engine power loss. A gradual loss of engine power occurs as the temperature of the fuel increases. Electronic engines will correct for higher fuel temperatures to a limit. Consult your Caterpillar engine dealer for information.Fuel Filters
A primary fuel filter and/or water separator is installed between the fuel tank and the engine mounted fuel filter. The location of the primary fuel filter is important in cold weather operation. The primary fuel filter and the fuel supply line are commonly affected by cold fuel. The best location for the primary fuel filter is in the engine compartment, where the primary fuel filter will benefit from the radiant heat of the engine. A primary fuel filter that is mounted outside the frame rails, or in any location that is exposed to wind, can be a persistent problem in cold weather.Engine Lubrication Oil Viscosity
Proper engine oil viscosity is essential to ensure engine starting at cold ambient temperatures. Refer to the Lubricant Viscosity chart for recommended oil viscosities to use at various operating temperature ranges.Oil Pan Heater
Oil pan heaters are useful devices to assist in reducing the cranking amperage that is needed to start the engine. Oil pan heaters improve the flow of oil at start-up and reduce the time that is needed to warm the engine up. Oil pan heaters also increase the service life of bearings. Oil pan heaters can reduce the normal minimum ambient temperatures -20°C (-5°F) at which multi-grade API CG-4 oil can be used. Consult your vehicle dealer for more information.Coolant Recommendations
Engine coolant should offer the correct mixture of glycol and water for the lowest minimum ambient temperature expected. Refer to the Coolant Specifications.Check the coolant frequently in cold weather for glycol concentration in order to ensure adequate freeze protection.Jacket Water Heater
A jacket water heater can improve the startability and reduce warm up
