How to drain the coolant circuit
Warnings!
• Discard the used coolant in a safe place and in
accordance with local regulations.
• Do not drain the coolant while the engine is still
hot and the system is under pressure because
dangerous hot coolant can be discharged.
1.
Remove the coolant filler cap (figure 2 item 1).
2.
Remove the drain plug (figure 3 item 1) from the
heat exchanger.
3. After the system has been drained, fit the filler cap
and the drain plug.
4. Fasten a label in a suitable place to indicate that
the coolant system has been drained.
Caution: The closed circuit system cannot be drained
completely. If the coolant is drained for engine
preservation purposes or for protection from frost, the
coolant system must be filled again with an approved
antifreeze mixture.
Engines fitted with keel coolers
The coolant capacity and the method used to drain
the coolant circuit of an engine connected to a keel
cooler will vary in different applications.
Use the instructions given by the keel cooler
manufacturer to drain and renew the engine coolant if
a keel cooler is fitted.
