IMPORTANT: Do not damage connected water hoses. Reposition expansion tank as far as possible until coolant level switch (2) forms the highest point. This will prevent coolant from escaping on opening. If necessary, catch escaping coolant and feed back in later.

Disconnect plug connection (1).

Turn coolant level switch (2) approx. 90° in direction of arrow and pull out.
