G3500 Engines 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 air starting motors, a larger volume of starting air and/or a higher air pressure may be necessary to start the engine at colder temperatures.

For electric starting, extra battery capacity may be necessary.

Consult your Cat dealer for more information on the starting aids that are available for cold weather starting.
