Hints for Cold-Weather Operation
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. An engine can be shut down for a period and the retained heat within the engine will allow the engine readily start.
Install the correct specification of engine lubricant before the beginning of cold weather. Refer to this Operation and Maintenance Manual, "Fluid Recommendations" for the recommended viscosity of oil.
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 by ensuring that the engine is allowed to operate at normal operating temperature.
Fill the fuel tank at the end of each shift.
Check the air cleaners and the air intake daily. Check the air intake more often when you operate in snow.
If equipped, ensure that the cold weather starting aid is operating correctly
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 lubrication properties and wear protection that the oil provides for the engine. Refer to this Operation and Maintenance Manual, "Fluid Recommendations" for the recommended viscosity of oil.At temperatures below −10° C (14° F) damage to engine components can occur if the engine is allowed to operate at high load and speed immediately after starting.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 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 up time is reduced.An electric block heater can be activated once the engine is stopped. A block heater can be 110 V dc or 240 V dc. Consult your Cat dealer for more information.Idling the Engine
The engine should not be “raced” to speed up the warm-up process.While the engine is idling, the application of a light load (parasitic load) will help in achieving the minimum operating temperature. The minimum operating temperature is 80° C (176° F).Recommendations for Coolant Warm Up
Warm up an engine that has cooled below normal operating temperatures due to inactivity. This warm -up should be performed before the engine is returned to full operation. During operation in cold temperature conditions, damage to engine valve mechanisms can result from engine operation for short intervals. This damage can happen if the engine is started and the engine is stopped many times without being operated to warm-up completely.When the engine is operated below normal operating temperatures, fuel and oil are not burned completely in the combustion chamber. This fuel and oil causes soft carbon deposits to form on the valve stems. Generally, the deposits do not
