Oil pan immersion heaters are not recommended for heating the lube oil. To ensure the compatibility of the components, only use equipment that is recommended by Caterpillar.A jacket water heater is required for starting when the temperature is less than 16 °C (60 °F). The jacket water heater can maintain the water temperature at approximately 32 °C (90 °F). The heated water will help to keep the oil in the engine block warm enough to flow when the engine is started. For engines with Multitorch spark plugs, the jacket water coolant temperature must be 42 °C (108 °F) or greater for starting.For air starting motors, a larger volume of starting air and/or a higher air pressure may be necessary in order to start the engine at colder temperatures.For electric starting, extra battery capacity may be necessary.Consult your Caterpillar dealer for more information on the starting aids that are available for cold weather starting.
