Preservative oil
Suitable preservative oil can be supplied by most petroleum companies.
E.g. Dinitrol 40 or the equivalent.
Preparations for storage
- Drain and flush the cooling system. Top up with preservative coolant.
- Warm up the engine on regular fuel. Stop the engine and drain the oil.
- Change the fuel filter and turbo filter.
- Fill the engine with preservative oil up to the minimum level on the
dipstick.
- Mix 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 (not single-speed engines)
for 20-25 minutes.
- Stop the engine, remove the hoses and connect the regular fuel lines.
- Oil the valve mechanism generously with preservative oil.
- Remove the injectors and spray preservative oil into each cylinder,
max 30 cm
3
(ml).
Turn the engine over a few times using the starter motor. Spray a small
amount of oil additionally into each cylinder.
After this the engine must not be cranked. Refit the injectors.
- Drain the preservative oil from the engine. Fresh engine oil can be filled
directly or when the engine is taken out of storage.
- Drain the coolant if the engine is not to be stored with a full cooling
system. Plug and tape over all coolant connections (if the cooling system
is not completely assembled).
- Air cleaner: Clean or change the filter element.
- 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 bright engine parts, first with penetrating
preservative oil such as Dinitrol 25B and then with Dinitrol 112 or the
equivalent.
Use a container to avoid spillage
when draining the oil and
coolant.
Dispose of used oil and coolant
through an authorised waste
disposal contractor.
