Preparing the engine for storage
Preparing the engine for
storage
If the engine is not being used for an extended
period its cooling system, fuel system and com-
bustion chamber and outside must be protected
against rust.
The engine can normally stand idle for up to
6 months without needing preparation. For
longer periods of than 6 months, however, the
measures in the following sections must be tak-
en. These measures provide protection for ap-
proximately 3 years, then the preparing
procedure must be repeated. An alternative to
preparing the engine for long-term storage is to
start the engine and warm it up every 6 months.
Preparation means that the following measures
are taken:
• The engine is cleaned thoroughly.
• Run the engine for a specific period using
special preservative fuel, oil and coolant.
• Otherwise prepare the engine for storage (fil-
ter renewal, lubrication, etc.).
Preservative products
Preservative oil
Use a normal engine oil that meets the require-
ments in the Oil grade
section.
Preservative coolant
Use coolant containing 50% by volume of gly-
col. Example: BASF MPG Glysacorr P113 and
Valvoline Zerex P113 FP.
Ethylene glycol can be fatal if ingested and can
cause skin irritation and eye damage.
Preservative fuel
Preservative fuel must not contain biodiesel.
Even small amounts of 5-10% biodiesel can have
adverse effects on the engine when in long-term
storage.
Long-term storage of diesel, where the diesel
comes into contact with water, may lead to the
growth of micro organisms (bacteria and fun-
gus).
In order to minimise the growth of micro-organ-
isms, preservative fuel should contain the fol-
lowing additives. The additives should be
selected and added by the fuel supplier.
Preservative fuel should comply with the follow-
ing requirements:
• 0% biodiesel.
• Max. sulphur content 50 ppm.
• Max. water content 200 ppm.
• The fuel must contain additives to stop the
growth of micro-organisms.
