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 engine oil
Use a normal engine oil that meets the require-
ments in the
section.
Preservative oil for combustion
chambers
Suitable preservative oils are supplied by most
oil companies. Use a preservative oil based on
mineral oil and propellant which must be com-
pletely ventilated away.
The oil should have as few other additives as
possible and must not contain PTFE or silicone.
An example of a good product to use is CRC Mo-
tor Protect.
Preservative coolant
Use coolant containing 50% by volume of gly-
col. Example: BASF MPG Glysacorr P113 and
Valvoline Zerex P113 FP.
WARNING!
Ethylene glycol can be fatal if ingested and can
cause skin irritation and eye damage.
Preparations for storage
Environment
Use a suitable container. Used oil and coolant
must be disposed of as specified in national and
international laws and regulations.
1.
Remove plugs and tape from the coolant
connections, air intake and exhaust pipe.
2.
Drain the oil.
3.
Renew the oil filter and fuel filter in the gas
supply installation.
4.
Clean the centrifugal oil cleaner.
5.
Fill with engine oil to the minimum level on
the oil dipstick.
6.
Drain and flush the cooling system of any old
coolant.
7.
Top up with preservative coolant.
