Filling with coolant
NOTE! Coolant should be filled with the engine
stopped and cold.
NOTE! For filling D2D-B MP with coolant, see
Op-
erator's Manual
.
External systems: When external systems are con-
nected to the engine’s cooling system, the valves to
the systems should be opened and the units vented
during filling.
NOTE! Adjust coolant level in accordance with the
pressure in the system. Measure pressure in the ex-
pansion tank and
below coolant level. Test outlet ()
alternative test point (2).
Cold engine: 0 kPa (0 psi)
Warm engine: Approx. 0 kPa (.5 psi) below
release pressure of the pressure
cap (3).
D5/D7/D9/D11/D16: The cooling system has no vent-
ing nipples. It is automatically vented.
Fill until the system is completely filled up, including
the expansion tank.
Start the engine and let it run without load at 000–
500 rpm for 5–20 minutes. Check coolant level.
D12: Open all venting nipples when filling. Fill at the
rate of approximately 0 – 5 l/min (2.5 – 4.0 US
gal/min).
Close the venting nipple(s) as no bubbles can be
seen in the coolant.
Fill until the system is completely filled up, including
the expansion tank.
Start the engine and let it run without load at 000–
500 rpm for 5–20 minutes. Check coolant level.
D9/D11/D12/D16: The coolant level should reach the
lower edge of the filler pipe. All D9/D and D6 en-
gines are equipped with low coolant level alarm.
IMPORTANT! The engine must not be started
until the system has been vented and com-
pletely filled.
WARNING! Do not open the pressure cap or
the venting nipples on a hot engine. Steam or
hot water can spray out and the pressure thus
lost.

D5/D7: The coolant level should reach the lower
edge of the filler pipe. The level must be visible from
top of the compensationtank.
