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

        1.
        | 
       
        Fill the cooling system with
        
         40 - 93 170 402 Coolant
        
        to approx. 30 mm above the mark on the expansion tank (coolant is blended - equal parts coolant and water).

       | 
        2.
        | 
       
        Open the air vent cock on the coolant pipe and release the air.
         
         
        
          
        
         
        | 
      
     
    
   
   
    
     
      
       | 
        3.
        | 
       
        Close the air vent cock and fit the coolant reservoir cap.
