7. Run the engine for a short period to distribute
lubricating oil and coolant throughout the engine.
8. Clean out the engine breather pipe (where fitted)
and seal the end of the pipe.
9. Remove the fuel injectors and spray clean engine
lubricating oil into cylinder bores. Divide four ounces
(118,3 ml) of lubricating oil evenly between the four
cylinders.
10. Remove the air filter and any pipe installed between
the air filter and the induction manifold. Seal the
manifold with waterproof tape.
11. Remove the exhaust pipe. Seal the manifold with
waterproof tape.
12. Disconnect the battery and store it safely, in a fully
charged condition. Before the battery is put into
storage, give the battery terminals a protection
against corrosion with a light coating of dielectric
grease or petroleum jelly.
13. Seal the vent pipe of the fuel tank or the fuel filler
cap with waterproof tape.
14. Remove and store the fan drive belt.
Note: Before starting the engine after storage, operate
the starter motor with one of the fuel shut-off solenoid
wires disconnected for 15 seconds or until the dash
panel low oil pressure warning indicator goes out. This
will allow oil to be circulated throughout the engine to
prevent damage to internal components.
