4.11 Block Heaters

Block heaters are recommended on all standby applications where the generator is subject to temperatures below 60° F (16°C) and are available as installed accessories on all generator sets. The block heater should be connected to a source of power, which is determined by the particular size and type of heater.

Note: BLOCK HEATER DAMAGE! Do not energize block heater until engine block is filled with coolant and the generator set is run to remove trapped air. Otherwise, block heater failure will result. Unplug block heater prior to draining cooling system.

4.12 Recommended Coolant

Antifreeze/coolant protection will be required for most applications. This must be performed prior to startup of generator set and energizing block heater(s).

A solution of 50% ethylene glycol and 50% clean, softened water is recommended to provide freezing protection to --34°F (--37°C) and boiling protection to 256 °F (129 °C). A 50/50 solution will also inhibit rust and corrosion. Follow the engine manufacturer’s recommendations when available.

For most diesel engines, an additional inhibitor additive is required to prevent cavitation erosion. Refer to the engine operation manual for inhibitor section and concentration level recommendations.
