4.4 Checking Coolant Level
Do not open the coolant filler cap when the
engine is hot, except in emergencies, as
this could cause serious personal injury.
Steam or hot fluid could spray out.
IMPORTANT:
Only use coolant recommended by Volvo
Penta. Top up with the same type of
coolant as already used in the system.
Different types of coolant must not be
mixed.
NOTICE! Only fill coolant with the engine
stopped. Fill slowly, to allow air to flow out.
Check coolant level daily before starting.
Coolant Level, Checking and Topping

Filling a completely empty system
NOTICE! Mix the correct amount of coolant in
advance, to ensure the cooling system is completely
filled. Refer to Technical Data, page 89 for the correct
coolant volume.
NOTICE! Do not start the engine until the system is
vented and completely filled.
1 Open the caps to both the expansion tank (1 and 2)
and radiator (3).
2 Fill coolant into the expansion tank until it is
completely full, to the MAX mark on the sight glass.
3 Fill the radiator. If nipples are fitted to the
connections at the bottom of the radiator (4) these
can also be used to fill the radiator.
