Genset Cold Weather Operation - Vanguard CPW 125-4-S Series Operation And Maintenance Manual

Genset Cold Weather Operation

It is possible to operate the genset-engine in extremely cold environments, if properly prepared and maintained. Satisfactory
performance of the genset-engine in low ambient temperature conditions requires modification of the engine, the
surrounding equipment, operating practices, and maintenance procedures.
The correct engine coolant lubricating oil and fuels must be used for the cold weather range in which the engine is being
operated. Refer to Cummins® Operation and Maintenance Manual QSB4.5 and QSB6.7 Engine (Bulletin 4021531), Cold
Weather section for recommendations for critical engine fluids; see the appendices at the end of the Weld-Deck Operation
and Maintenance Manual, Weld-Deck welding package CPW 125-4-S2-4.
A 750W/120VAC coolant heater (1), and a 150W/120VAC oil heater (2) are fitted to the standard engine. Both plug into an
external 120VAC power source. Contact Vanguard equipment for optional heaters.

Other provisions for operating cold weather must also be taken into account, such as but not limited to: battery heaters, fuel
heater, etc. Refer to CUMMINS® Operation and Maintenance Manual QSB4.5 and QSB6.7 Engine (Bulletin 4021531) Cold
Weather section in the appendices at the end of this manual for complete details.
Note: To reduce the possibility of damage to the lubricating oil pan, due to the composite materials used in the manufacture
of the lubricating oil pan, under no circumstances should an external heat source be applied directly or indirectly to the
lubricating oil pan.
