                     The cooling system is under pressure. Hot coolant and steam can escape.

        1.
        | 
       
        Switch the engine off and let the engine cool down.

        2.
        | 
       
        Remove the expansion tank cap.

       | 
        3.
        | 
       
        Use 32 025 077 Fluid tester and check the coolant's freezing point. Adjust if necessary, use 40 - 93 170 402 Coolant. (The coolant is mixed with water, equal parts of each.)

       | 
        4.
        | 
       
        Check coolant level and correct the coolant to "COLD" mark if necessary (black arrows).

       | 
        5.
        | 
       
        Fit the expansion tank cap.

        2.
        | 
       
        Remove the expansion tank cap.

       | 
        4.
        | 
       
        Check coolant level and correct if necessary. Correct level for cold, vented system (filling level) is the mark for "cold" (1).
