Check the oil level using the dipstick

Is the oil level above the 'oo' mark?

Add oil of the same viscosity if needed

CAUTION: The cooling water in the engine reaches extremely high temperatures. You must use extreme caution when working on hot engines to avoid burns. Allow the engine to cool before working on the cooling system. Open the filler cap carefully, using protective clothing when the engine is warm.

Check the coolant level each day before starting the engine.

Remove the pressure cap from the expansion tank and check water level.

Ensure coolant level is about 1 3/4 in. (4-5 cm) below the filler cap sealing surface when the engine is cold.

Open the venting cock on top of the turbocharger when filling with coolant to prevent air pockets.

Check the pressure valve in the filler cap releases at approximately 7 PSI (0.5 bar) using a cap pressure tester.

Ensure all special tools are available

Fit protective caps over the nozzle tips and line connections

Ensure fuel delivery lines are not bent

Hold male union of nozzle line stationary with a backup wrench when loosening fuel pressure lines

Loosen nuts to remove leak-off lines and T-fittings

Remove the cooling water pipes between the heat exchanger and the water pump inlet

Disconnect hose to seawater pump

Unscrew the attaching bolts holding the heat exchanger to the expansion tank

Remove bolts holding heat exchanger cover
