Preservative oil
Suitable preservative oil can be supplied by most oil companies.
E.g. Dinitrol 40 or the equivalent.
Preparations for storage
- Drain and flush the cooling system. Fill with preservative coolant.
- Run the engine until warm with ordinary fuel. Stop the engine and drain
the oil.
- Change fuel filter and turbo filter.
- Fill the engine with preservative oil to the minimum level on the
dipstick.
- Mix the preservative fuel in a can. Detach the fuel pipe at the feed pump
suction line and connect a hose from the can.
- Detach the fuel pipe at the overflow valve and connect a return hose to
the can.
- Start the engine and run it at about 1000 rpm for 20 - 25 minutes.
- Stop the engine, remove the hoses and connect the normal fuel lines.
- Oil the valve mechanism with plenty of preservative oil.
- Remove the injectors and spray preservative oil into each cylinder
max. 30 cm
3
(ml).
Crank the engine several revolutions using the starter motor. Spray a
small amount into each cylinder.
The engine must not then be cranked. Refit the injectors.
- Drain the preservative oil from the engine. New engine oil can be filled
directly or when taken out of preservative.
- Drain the coolant if the engine is not to be stored with a full cooling sys-
tem. Plug and tape over all coolant connections (if the cooling system is
not completely assembled).
- Air cleaner: Clean and change the filter insert.
- Cover air intakes and exhaust pipes.
- Alternator and starter motor:
- Spray with water-repellent anti-corrosive oil, CRC 226, LPS1 or the
equivalent.
- Spray the outside of shiny engine parts, first using penetrating preserva-
tive oil such as Dinitrol 25B and then using Dinitrol 112 or the
equivalent.
Always use suitable containers
to avoid spillage when
draining oil and coolant.
Dispose of used oil and coolant
through an authorized waste
disposal contractor.
