NOTE! Close the bottom valve before working on the
cooling system.
R efrig erant
The refrigerant has the twin purpose of protecting the
cooling system from freezing and preventing corrosion.
Antifreeze
Use a mixture of 50 % Volvo Penta antifreeze (glycol) and
50
% pure water (as neutral as possible). This mixture
prevents freezing down to approx. -40°C (-40°F) and
should be used all year round.
Fig. 105. Draining of the refrigerant
Note: At least 40 % antifreeze should be used in the sys-
tem to ensure satisfactory corrosion protection.
Mix the antifreeze with water in a separate vessel before
filling the cooling system.
For replenishment of the refrigerant see the instruction on
page 64.
The sea water system
Watch out for the penetration of water in the boat!
WARNING! Antifreeze is hazardous to health
(dangerous to consume).
1. Close the bottom cock or the cock on the S-
drive. Release the cover on the sea water pump
and let the water run out.

In the event that antifreeze is not necessary it is appropri-
ate to add Volvo Penta anti-corrosion agent 1141526-2.
2. Release the hose from the sea water pump and
sea water filter at the reverse gear and tilt down so
that the water runs out.
3.
Check if there are additional cocks/plugs at low
points on the refrigerant and exhaust pipes.
Check carefully that all the water runs out.

Pump out the boat and check that there is no
leakage.
1.
Unscrew the filler cap. Turn the cap to the first stop
and wait a moment before lifting off the cap.
WARNING! Open the filler cap very carefully if
the engine is hot. Steam or hot liquid may spit
0
out.
2.
Connect a hose to the drain cock. Open the cock
and drain out the refrigerant in a vessel.
Hand in the mixture to a recovery station if it is
not to be used again. Never pollute the water.
