5 Drain the coolant after 1-2 days of operation.
Remove the filler cap and possibly the lower radia-
tor hose to increase the speed of emptying.
To prevent suspended material from settling back
in the system, emptying should be done rapidly,
within the space of 10 minutes, when the engine
has not been standing still for a long time.
6 Flush the system immediately and thoroughly with
clean hot water to prevent dirt from settling in the
inner areas. Flush until the water that runs out is
completely clean. Make sure that any heater con-
trols are set to full heating during emptying.
7 If contamination should still be left after a long
period of flushing, you can do a cleanout with Volvo
Penta radiator cleaner, followed by finishing-off with
Volvo Penta neutralizer. Carefully follow the
instructions on the package. Otherwise, continue
as in item 8 below.
8 When the cooling system is completely free from
contamination, close the drain taps and plugs.
9 Fill up with Volvo Penta recommended coolant, fol-
lowing the instructions in the chapters entitled
.
