Fuel, Oils, Coolant - Volvo Penta TAMD63L Instruction Book

Fuel, Oils, Coolant

Diesel fuels
The composition of the fuel is vital for operation of the
engine, its service life, and emissions. To meet the
performance specified and to run your boat cleanly
and quietly, it is vital that you use fuel as recommend-
ed below.
Fuel specification
Fuel must meet national and international standards.
For example:
– EN 590 (with national environmental and cold
weather standards)
– ASTM-D975 No. 1-D, 2-D
– JIS KK 2204
Sulfur content: According to statutory requirements.
Note. Large variations occur in merchant fuel specifi-
cations which have influence on engine power output
and fuel consumption.
Declared power is measured with fuel acc. to ISO
3046 with a lower calorific value of 42.700 kJ/kg and a
density of 840 g/liter at +15
Lubricating oil, engine
A lubricating oil of a quality as shown in the table
below should be used:
Designation Standard
VDS, VDS-2* Volvo Drain Specification
CD, CE API (American Petroleum Institute)
MIL-L-2104D US Government's Military Spec.
* Note. A VDS oil must be used if there is to be a long period
between oil changes. See also the maintenance schedule and
"Technical Data".
We do not advise that you run on an oil of a quality
which does not meet the above requirements. This is
a poor solution with respect to both economy and
operating safety.
For viscosity and capacities, see "Technical Data" on
page 108.
Lubricating oil, reverse gear
For the reverse gear, a single grade oil of quality
CC, CD or CE according to the API system should be
used. Oil according to the MIL-L-2104D standard may
also be used.
For quality and capacities, see "Technical Data" on
pages 110–113.

o C (59 o F).
Oil for servo unit system, hydraulic pump
(accessory)
ATF oil* should be used in the servo unit system.
* ATF = Automatic Transmission Fluid (oil for automatic gear-
boxes).
Coolant
The engine's internal cooling system (freshwater
system) is filled with a mixture of freshwater and
additives. NOTE! Never use freshwater without
additives. The following recommendations should be
followed to prevent frost and corrosion damage to your
engine:
If there is a risk of freezing
Use a mixture of 50% Volvo Penta antifreeze (glycol)
and 50% pure water (as neutral as possible). This
mixture will protect against freezing to a tempera-
ture of approx. – 40°C (– 40°F) and should be used
all year round.
Note. There should be at least 40% antifreeze in the
system for complete protection against corrosion.
NOTE! Glycol is harmful to health (danger-
ous if ingested).
If there is no risk of freezing
When there is no risk of freezing water with added
Volvo Penta anti-corrosion agent* (P/N 1141526-2)
may be used unless an anti-freeze mixture is used all
year round. Mixture ratio = 1:30.
See instructions on page 59 for topping up engine
coolant. Run the engine once the coolant has been
topped up to allow the additives to work.
NOTE! Anti-corrosive agents are harmful to
health (danger if ingested).
* Note. Never mix antifreeze (glycol) and anti-corrosive agents.
The two combined can produce foam and drastically reduce the
coolant's effectiveness.
Replacing the coolant
The coolant should be replaced and the system
flushed at least once a year. See maintenance sche-
dule.
