GAUGE 2G8516 - Caterpillar

Caterpillar Diesel Engines can operate effectively in cold weather. During cold weather, the starting and the operation of the diesel engine is dependent on the following items:
The type of fuel that is used
The viscosity of the engine oil
The operation of the glow plugs
Optional Cold starting aid
Battery conditionRefer to Special Publication, SEBU5898, "Cold Weather Recommendations for Caterpillar Machines".This section will cover the following information:
Potential problems that are caused by cold-weather operation
Suggest steps which can be taken in order to minimize starting problems and operating problems when the ambient air temperature is between “ 0° to −40 °C (32° to -40 °F)”.The operation and maintenance of an engine in freezing temperatures is complex . This complexity is because of the following conditions:
Weather conditions
Engine applicationsRecommendations from your Caterpillar dealer are based on past proven practices. The information that is contained in this section provides guidelines for cold-weather operation.Hints for Cold Weather Operation
If the engine will start, operate the engine until a minimum operating temperature of 80° C (176° F) is achieved. Achieving operating temperature will help prevent the intake valves and exhaust valves from sticking.
The cooling system and the lubrication system for the engine do not lose heat immediately upon shutdown. This means that an engine can be shut down for a period and the engine can still start readily.
Install the correct specification of engine lubricant before the beginning of cold weather.
Check all rubber parts (hoses, fan drive belts) weekly.
Check all electrical wiring and connections for any fraying or damaged insulation.
Keep all batteries fully charged and warm.
Fill the fuel tank at the end of each shift.
Drain the water from the fuel system. Refer to this Operation and Maintenance Manual, "Fuel System Primary Filter/Water Separator - Drain".
Check the air cleaners and the air intake daily. Check the air intake more often when you operate in snow.
Ensure that the glow plugs are in working order. Refer to Troubleshooting , "Glow Plug Starting Aid - Test".
Personal injury or property damage can result from alcohol or starting fluids.Alcohol or starting fluids are highly flammable and toxic and if improperly stored could result in injury or property damage.
Do not use aerosol types of starting aids such as ether. Such use could result in an explosion and personal injury.
For jump starting with cables in cold weather, refer to the Operation and Maintenance Manual, "Starting with Jump Start Cables." for instructions.Viscosity of the Engine Lubrication Oil
Correct engine oil viscosity is essential. Oil viscosity affects the amount of torque that is needed to crank the engine. Refer to this Operation and Maintenance Manual, "Fluid Recommendations" for the recommended viscosity of oil.Recommendations for the Coolant
Provide cooling system protection for the lowest expected outside temperature. Refer to this Operation and Maintenance Manual, "Fluid Recommendations" for the recommended coolant mixture.In cold weather, check the coolant often for the correct glycol concentration in order to ensure adequate freeze protection.Engine Block Heaters
Engine block heaters (if equipped) heat the engine jacket water that surrounds the combustion chambers. This heat provides the following functions:
Startability is improved.
Warm
