Recommended compartment warm-up procedure must be followed. Refer to the machine Operation and Maintenance Manual. Also refer to the relevant “Lubricant Viscosities for Ambient Temperatures” tables footnotes in this Special Publication and to the “Warm-up Procedures for Machines that are used in Cold Weather - (Generic)” topic in this Special Publication.
Excessive engine idling time can contribute to excessive water in the crankcase oil, causing corrosion, sludge, and other problems. Excessive engine idling time can also lead to injector fouling, piston and combustion chamber deposits, corrosive damage, and increased oil consumption.
For proper selection of oil type and/or specification, refer to this Special Publication, "Engine Oil" section. Also, refer to the relevant “Lubricant Viscosities for Ambient Temperatures” tables in this Special Publication.For the proper selection of oil viscosity grade, refer to the relevant “Lubricant Viscosities for Ambient Temperatures” table in this Special Publication. Also, refer to this Special Publication, "Lubricant Viscosities" article.
Not following the recommendations found in the “Lubricant Viscosities for Ambient Temperatures” tables and associated footnotes can lead to reduced performance and engine failure.
Do NOT use only the oil viscosities when determining the recommended oil for an engine compartment. The oil type (performance requirements) MUST also be used.
For easier cold weather starting, make sure that all the components of the engine electrical system are properly maintained. All electrical wiring and connections should be free of the following: fraying, damaged insulation, and corrosion. Batteries should be kept fully charged and warm. The batteries and the battery cables need to be the proper size for the application.Various starting aids are available to assist with cold engine starts in low temperature conditions. Follow the recommendations that are provided by the manufacturer of the starting aid. Refer to the “Aftermarket Products and Warranty” article in the " Warranty Information" section of this special publication.Additional information on cold-weather operation is available in Special Publication, SEBU5898, "Cold Weather Recommendations For All Caterpillar Equipment". This publication is available from your Cat dealer.Additionally, for more information on cold-weather operation, refer to this Special Publication, "Fuel Specifications" section. Also refer to this Special Publication, "Cooling System Specifications" (Maintenance Section).Before attempting to start the engine, make sure that the oil in the engine is fluid enough to flow. Check the oil by removing the dipstick. If the oil will drip from the dipstick, then the oil should be fluid enough to allow the engine to start. Do not use oil that has been diluted with kerosene. Kerosene will evaporate in the engine. Evaporation will cause the oil to thicken. Kerosene will cause swelling and softening of the silicone seals. Kerosene will dilute the oil additives. Dilution of the oil additives will reduce the oil performance, and reduce the engine protection that the additives provide. If your machine is equipped with a gasoline starting engine (earlier machine), make sure that the oil is fluid enough to flow.If the viscosity of the oil is changed for colder weather, also change the filter element. If the filter is not changed, the
