1 Corrosion protection
The various parts of the engine (except the
engine block) have been treated with an
anti-corrosion protective medium. In order
to prevent corrosion, the engine should
be rinsed off to remove any salt residues.
If there is any corrosion, the paint should
be touched up. Engine parts that become
hot must be touched up with heat-resistant
paint.
2 Zinc anode
There is a zinc anode in the heat exchang-
er to protect engine parts that come into
contact with the external water from gal-
vanic corrosion.
The speed at which the zinc anodes are
sacrificed depends on many external fac-
tors.
Check the zinc anodes; a new zinc an-
•
ode is 13 mm (
1
/
2
”) in length; if a zinc an-
ode is shorter than 6 mm (
1
/
4
”)it should
be replaced.
