Preparing the engine for storage Preservative oil 10. Drain the preservative oil from the engine. Fill with new engine oil immediately or when the engine is to be reused. Suitable preservative oils are supplied by most oil companies. Example: Dinitrol 40 or equiva- lent. 11. Drain the coolant if the engine is not to be stored with coolant in the system. Plug and tape all coolant connections if the engine is to be stored without a cooling system. Preparations for storage 12. Air cleaner: Clean or renew the filter ele- ment. Environment 13. Cover air intakes and exhaust pipes. Use a container to avoid spillage when draining the oil, coolant and reductant.
Dispose of used fluids through an authorised waste disposal con- tractor. 14. Alternator and starter motor: Spray with wa- ter-repellent anti-corrosive oil, CRC 226, LPS1 or the equivalent. 15. Spray the outside of bright engine parts, first with penetrating preservative oil such as Dinitrol 25B and then with Dinitrol 112 or the equivalent. 1. Drain and flush the cooling system. Top up with preservative coolant. 2. Warm up the engine on normal fuel. Stop the engine and drain the oil. Clearly mark the engine with the storage prepa- ration date, and state that the engine must not be started or cranked. 3. Renew the fuel filter. 4.
Fill the engine with preservative oil up to the minimum level on the oil dipstick. If the engine is to stand idle for more than a year: 16. Drain the reductant from the reductant tank. 5. Mix preservative fuel in a can. Detach the fuel pipe at the feed pump suction line and connect a hose from the can. 6. Detach the fuel pipe at the overflow valve and connect a return hose to the can. 7. Start the engine and run it at about 1,000 rpm for 20-25 minutes. 8. Stop the engine, remove the hoses and con- nect the normal fuel pipes. 9. Remove the rocker covers and lubricate the valve mechanisms with plenty of preserva- tive oil. Refit the rocker covers. Note: Do not remove the injectors.
