Preserving Engine - Volkswagen Marine SDI Series Operating Manual

Preserving engine

Preparing engine for winter
Depending on the operating conditions,
Volkswagen Marine boat engines must
be protected against possible corrosion
damage.
It is not necessary to use special corrosion
protection oils (see engine oil specifications
on page 32).
Changing engine oil and oil
filter element
For units you shut for longer periods
- e.g. after the end of the season - please
carry out preservation in the specified
order:
1 - Thoroughly clean all parts to be
preserved.
2 - Allow the engine to warm up.
3 - After switching off the engine, renew
the oil filter element and pump off the
engine oil - see page 36 and 34.
4 - Add 6.0 litres of engine oil and run the
engine for approximately 30 seconds at
increased idling speed.
5 - Switch the engine off.
INSPECTION
6 - Plug all openings (e.g. exhaust pipe, air
filter) to prevent the penetration of dirt
or moist air.
7 - Spray the engine with an anti-corrosion
agent from the outside.
A corresponding anti-corrosion agent is
available from VW Marine Service
Partners.
Note
On engines that run at least 20 minutes
under load every two weeks, no corrosion
protection is required. However, the engine
oil must be changed at the intervals speci-
fied in the service schedule.
