  • Page 47: Cooling System

    The Volvo Penta Genset comes with an internal freshwater system connected to an engine mounted heat ex- changer, a radiator cooler, or prepared for external cooling, e.g. keel cooling or central cooling.

  • Page 48: Engine Mounted Heat Exchanger

    Maintenance: Cooling system general Engine mounted heat exchanger The system includes two circuits. The freshwater system is cooling the charge air, the cylinder liners and the cy- linder heads. An engine driven cooling water pump circulate the coolant through the heat exchanger and through the engine.

  • Page 49: Radiator Cooling

    Maintenance: Cooling system general Radiator cooling The engine cooling water is cooled by a radiator in a one-circuit cooling system. Air is forced through the radiator by an engine driven cooling air fan. The charge air is cooled in an air-to-air charge air cooler mounted in front of the radiator and it make use of the air flow from the engines cooling fan before it enters the radiator.

  • Page 50: Keel Cooled

    Maintenance: Cooling system general Without engine mounted heat exchanger (Keel cooled) The engine cooling water is cooled by, e.g, a box cooler, a grid cooler, or any other external heat exchanger. The same coolant (fresh water) is cooling the complete engine (charge air, cylinders, etc.). 1.

  • Page 51: Freshwater System

    Maintenance: Freshwater system Freshwater system Coolant level check Coolant level can be checked through a level glass on top of the expansion tank. The green float must be vi- sible in the level glass. The coolant level should be about five centimetres (2”) below the pressure cap sealing plane in the ex- pansion tank.

  • Page 52: Coolant Drain

    Maintenance: Freshwater system Coolant drain 1. Remove the filler cap from the expansion tank and open the vent tap by the turbocharger. 2. Connect a suitable hose to each drain point, refer to section ”Drain points”. Open the drains and al- low the coolant to drain off into a suitable vessel.

  • Page 53: Raw Water System

    Maintenance: Raw water system Raw water system The raw water system is the engine’s external cooling system and it is either a seawater system or a central coo- ling system. It cools the internal cooling system in an engine mounted or externally mounted heat exchanger. The system is protected against galvanic corrosion by zinc anodes located in the heat exchanger.
