Cooling system, draining

NOTE! Remove the expansion tank filler cap and close the hull fitting before draining the cooling system.

WARNING! Open the pressure cap very carefully if the engine is hot. Steam or hot coolant can spray out and cause burns.

1. Connect drain pipes. Open all drain points.

2. Check that all water drains out.

Check whether the installation has any further taps or plugs at the lowest points of the cooling water pipes and exhaust pipe.

3. Close the taps.

4. Pump the bilges out as necessary. Check that no leakage occurs.
