4.9. Engine Preservation Points for a Long Time

Preserved engine for a long time should be prevented from corrosion or entering faulty matters.

Especially the external and internal major components of the engine are likely to corrode.

Please take care of the engine to maintain its good performance as follows.

•

Drain the engine coolant completely and fill flesh water into the engine. Then run it sufficiently

until washing out the engine coolant line.

Finally drain the water, and refill new coolant (flesh water with 35 ~ 40% anti-freeze).

•

Run the engine until the temperature of engine coolant is reached to normal condition (71 ~

85 °C), after then stop the engine.

•

Drain engine oil by removing the drain plug of the oil pan or using the oil drain pump. Then

refill new engine oil up to “MAX” mark line and change oil filter cartridge to new one.

Prior to changing the oil, run the engine for 10 minutes. Drain engine oil while the engine is

still hot. It is helpful to drain the faulty matters attached in the bottom of the oil pan.

•

Close the valve or the cock of the fuel tank securely. Then detach the fuel filter and the water

separator to clean them or replace with a new one.

•

Run the engine about 5 minutes in order to circulate the new fuel through the all fuel lines

completely.

•

Disassemble the air filter to clean. If the element is fouled or worn severely, replace it with a

new one.

•

Drain the reduction gear oil completely, then clean the strainer that is assembled in the

reduction gear.

Refill the specified oil (SAE #30, above API CC grade) up to the “MAX” level.

•

While the engine is running at idle rpm for 5 minutes, shift the control lever position of the

reduction gear in turn (eg. “Neutral” - “Forward”- “Neutral” - “Reverse”) to circulate the oil

completely.

•

Put the engine throttle lever at the idle position then reduction gear and FPTO lever at “switch

off” position (Neutral & OFF).

•

Drain the engine coolant completely and let the drain plugs removed.

•

Close the kingston valve of the sea water line tightly. To avoid damage cause of freezing,

drain the water of the heat exchanger, inter cooler, reduction gear oil cooler completely and

keep the plugs opened.

Finally don’t forget to detach the sea water pump impeller and preserve it at a dark place.

•

First of all, disconnect the battery wire (negative pole), then detach the other cables.

Clean battery and all cables. After that replenish the distilled water for battery. (for refill type)

DAEWOO battery is maintenance free type, so there is no need to refill the water.

To protect corrosion, apply the grease on the wire terminals of the battery.

•

Loosen the V-belt(s) to release the pulley bearing from loaded tension and insert some pieces

of paper between V-belt(s) and the pulley grooves.

•

At least run the engine at idle rpm or a little more for 10 minutes once 10 days in order to

lubricate all lubrication system and charge the batteries of the engine.

•

The engine not used for a long time should be checked the condition regularly.

Apply the grease on the engine parts to keep from rust.
