Cooling System
Coolant
WARNING!
Ethylene Glycol coolant is poisonous to humans and
animals if ingested.
Carefully control all coolant removed from the engine,
quickly clean up all spilled coolant, and dispose of
coolant and absorbent materials according to local
environmental regulations.
WARNING!
Risk of eye injury. Eye protection required.
Coolant is an eye irritant. Always wear eye protection
when working with coolant.
Engines covered by this manual are filled at our factory
with the new, more advanced Volvo
VCS
yellow cool-
ant. If coolant needs to be added or replaced, only use
the
VCS
coolant.
Do not mix coolant types. Do not use other coolant
types such as traditional green ethylene glycol, propy-
lene glycol (pink), OAT or HOAT coolants.
Volvo Penta offers ready-to-use, pre-mixed containers
of the “VCS” coolant. If using full strength antifreeze,
use a 50/50 mix of antifreeze and distilled water. See
Freeze Protection
below.
Freeze protection
NOTICE!
Engine damage is possible during freezing
temperatures if coolant mix is not correct .
If the boat/engine will be stored or used in an area with
freezing temperatures, the coolant mixture must be
checked to insure it has adequate temperature protec-
tion properties. As part of winterization, Volvo Penta
highly recommends that the coolant be checked for
correct freeze protection. Use a coolant test kit (hydro-
meter) to check a sample of the coolant. The temper-
ature indicated by the hydrometer should be at least
10º F (6°C) lower than the lowest expected tempera-
ture for the area where the engine will be stored. Check
the coolant at ambient temperature, do not check hot
coolant (safety and inaccurate reading concerns).
The coolant solution can be strengthened to protect at
lower temperatures by draining half a gallon of coolant
from the engine and replacing with a half gallon of full
strength antifreeze solution. Run engine for 10 minutes
to ensure proper mixing of solution and recheck for
level of protection. Repeat, if necessary, until the indi-
