61 31 382 Replacing Level Switch For Coolant

Warning! Danger of scalding! Only perform this work after engine has cooled down.

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

Unscrew nuts (1). Pull coolant expansion tank (2) in direction of arrow out of grommet (3) underneath. Installation: Make sure coolant expansion tank (2) is correctly seated in grommet.
