Maintenance: Freshwater system

Checking the coolant level
WARNING! Stop the engine and allow it to cool
before opening the filler cap. Steam or hot cool-
ant may spurt out. Hot coolant and hot surfaces
can cause burns.
1. Turn the filler cap slowly counter clockwise and let
any pressure escape from the system before re-
moving the cap.
2. The coolant level should be between the MAX and
MIN marking on the expansion tank, when the en-
gine is cold.
3. Top up coolant if necessary. Reinstall the filler cap.
Draining the freshwater system
1. Remove the filler cap on the expansion tank (to al-
low the coolant to drain off faster).
2. Connect a hose to the draining nipple and open the
tap, let the water pour out into a suitable receptacle.
NOTE! Leave the old coolant to a facility for destruction.
