Central cooling system

The principle for connecting engines to a central
cooling system is the same as for a keel cooled en-
gine. See chapter

Function diagrams

.

The parameters given for Volvo Penta marine engines
under the heading

External cooling

also apply when

the engine is connected to a central cooling system.

Depending on the design of the central cooling sys-
tem, high static and dynamic pressures may occur.

Pressure limits for central cooling system
Pressure before coolant circulation pump
Pmax = 00 kPa (4.5 psi)
NOTE!

•

Max pressure before circulation pump is 00 kPa

(4.5 psi).

•

Min pressure before circulation pump when en-

gine is cold = 0 kPa (0 psi).

•

Min pressure before circulation pump when en-

gine is warm = 30 kPa (4.4 psi).
See

Expansion tank, function diagram

.

•

Pressure before seawater pump

P max = 00 kPa (4.5 psi)

•

In cases where seawater pump is excluded, max.

permitted pressure before charge air cooler = 250
kPa (36.3 psi)

•

In cases where the maximum coolant pressure of

the engine is exceeded, a heat exchanger capable
of handling the higher pressure must be connect-
ed in between the engine and the central cooling
system.

An extra expansion tank for the engine must also be
connected to the system. For further details see un-
der chapter

Extra expansion tank

.

Depending on system temperatures in the central
cooling system it may be possible to use the seawa-
ter-cooled version of an engine. However, the instal-
lation parameters laid down for Volvo Penta seawater
cooled engines must be observed.

In central cooling systems with several engines, each
engine must be fitted with coolant inlet and outlet
valves for service reasons.

IMPORTANT! When an engine is connected

to a central cooling system, the composition of
the coolant and its pH are extremely important.
See chapter

Coolant

.

NOTE! Always use Volvo Penta anti-freeze or anti-
rust agent. Both are available in concentrated form.
Mixing with other makes of coolants can give im-
paired corrosion protection, which may damage the
engine or block the cooling system.
