Antifreeze and anti-corrosion,
cleaning
Close sea cock before working on cooling
system.
To avoid loss of cooling performance caused by scaling
in the coolant system the coolant must be changed at
least once every other year. Another reason for chang-
ing the coolant is the risk of damage from corrosion in
freshwater systems due to corrosion inhibitor additives
losing their effect over time.
The system should be flushed carefully with tapwater
when changing the coolant. Flush until the water which
runs out of the draining holes is clean.
NOTE! Some parts of these engines’ cooling system
are made of aluminum. Chemical agents must not
be used for cleaning the system.
For information on draining the coolant, refer to: “Drain-
ing the coolant” on page 24. For coolant info. see “Cool-
ant” on page 16.
Filling with coolant
Note! Do NOT open the pressure cap or the
venting nipple(s) on a hot engine. Steam or
hot coolant can spray out and the system
pressure will be lost.
Filling should be carried out with the engine
stopped.
Do not fill so quickly that air locks form in the system.
Allow the air to flow out via the filling opening or venting
nipple(s).
1.
Open all venting nipples (L) during filling. The
TAMD162C has only one venting nipple.
2.
Fill with coolant until the system is completely filled
up. Close the venting nipple(s) when no bubbles
can be seen in the water flowing out of the venting
nipple(s).
3.
Run engine at idle speed for approx. two minutes.
4.
Check the coolant level. Top up if required. Install
pressure cap.
5.
Run engine to normal operating temperature at
approx. 1500 rpm. and at low load for at least 1
hour in order to ensure the engine coolant system
has no air in it.
6.
Check coolant level on the engine when COLD.
Top up coolant if required. The level should reach
the lower edge of the filler pipe.
If a heater system is connected to the engine’s cooling
system, the heater control valve should be opened and
the unit vented during filling.
For information on coolants refer to section “Coolant” on
page 16. Top up coolant with the same mixture as used
in the coolant system.
Seawater filter. Checking/cleaning
How often the filter is cleaned is dependent on the oper-
ating conditions. The interval can be decided based on
experience after running the engine for a time. If neces-
sary, clean the filter more often than specified in the
maintenance schedule.
It is vital that the flow of seawater is never restricted
in any way.
Close sea cock before working on cooling
system.
1.
Remove cover (1) and lift up the insert.
2.
Clean the insert and housing (2).
3.
Reinstall the parts as shown below. Check the
O-ring. Replace if required.
4.
Open the sea cock and check for leaks.
