Marine diesel engines. Operator’s manual
Coolant specifications
It is recommended use SOLÉ DIESEL 50% coolant or another coolant with similar
specifications. On the other hand, distilled water with an anti-freezing agent is also suitable. The anti-
freezing agent concentration according to operating conditions is specified in anti-freezing agent
package labels. It is advisable select the anti-freezing agent concentration based on a temperature
approx. 5ºC under the actual atmospheric temperature.
Other engine coolants may affect warranty coverage, cause an internal build-up of rust and
scale and/or shorten engine life.
Never mix different types of coolants. This may adversely affect the properties of the engine coolant.
Maintenance task. Coolant check
Allow the engine to cool. Release pressure from the cooling system before removing the
pressure cap. To release pressure, cover the pressure cap with a thick cloth and then slowly turn the
cap counterclockwise. Remove the cap after pressure has been completely released and the engine
has cooled. Check the coolant level at the tank, the level must be approximately 3/4 full.
Maintenance task. Coolant fill/change
1.
Drain off all the coolant by opening the two drain plugs, one in the heat exchanger and the
other in the cylinder block.
2.
Close the drain plugs.
3.
Remove bleeding bolt of thermostat holder.
4.
Refill to the hole in the tank cap with coolant
Maintenance task. Seawater filter inspection
Seawater pump impeller is neoprene and cannot rotate dried. If operated without water, the
impeller can be broken. It is important therefore that a spare impeller is always available. Impeller
inspection and replacement procedure:
1.
Close the seawater cock.
2.
Remove the seawater pump cover plate.
3.
Remove the impeller from the shaft.
4.
Clean the housing.
5.
Inspect the impeller for damaged, cranked, broken,
missing or flattened vanes. The impeller vanes should be
straight and flexible.
6.
If it is damaged replace with a new one.
7.
Lubricate the impeller with soapy water before installation.
8.
Install the impeller. During installation push and rotate the impeller in the same direction as
the genset rotation until it is thoroughly seated in the impeller housing.
