The jacket water heater is used for starting in temperatures as low as -18 °C (0 °F). The heated water will help to keep the oil in the engine block warm enough to flow when the engine is started.Maintain the proper level of electrolyte in the batteries. Keep the batteries fully charged.To maximize the battery power, heat the battery compartment or store the batteries in a warm location. Typically, batteries only have 50 percent of the capability at −10 °C (14 °F) versus 27 °C (80 °F).Extra battery capacity may be necessary for very cold temperatures.Consult your Caterpillar dealer for more information on the starting aids that are available for cold weather starting.
