INSPECTION

Reactive anode

Checking reactive anode of
coolant system and renewing
if necessary
Important
Observe the safety precautions
beginning on page 17 before
performing out any work on the
engine or
compartment.
The reactive anode in the cooling system
must be checked in accordance with the
specifications in the service schedule and
renewed if necessary.
Check the reactive anode, as it protects the
engine from galvanic corrosion.
A new reactive anode has a length
of dimension A = 20 millimetres -
see illustration.
The anode must be replaced with a new one
when more than 50 % (10 millimetres) of it
has been used.
Use only genuine Volkswagen Marine parts,
as an incorrect composition of the anode
can result in serious corrosion damage in
the engine.
