Removing and installing parts of cooling system
  Caution
When doing any repair work, especially in the engine compartment, pay attention to the following due to the cramped conditions:
t  Route all the various lines (e.g. for fuel, hydraulics, activated charcoal filter system, coolant and refrigerant, brake fluid and vacuum) and electrical wiring in their original positions.
t  Ensure that there is sufficient clearance to all moving or hot components.
  WARNING
Steam may escape when expansion tank is opened. Wear eye protection and protective clothing to avoid eye injuries and scalding. Cover cap with cloth and open carefully.
  Note
t  When the engine is warm, the cooling system is under pressure. If necessary, release pressure before beginning repair work.
t  Hoses are secured with spring-type clips. In case of repair, only use spring-type clips.
   
t  Spring-type clip pliers -VAS 6340- or spring-type clip pliers -VAS 5024A- are recommended for installation of spring-type clips.
t  When installing coolant hoses, position them so they are free of tension and do not come into contact with other components.
t  The arrows on the coolant pipes and on the ends of the hoses must be aligned with each other.
t  Renew gaskets and seals.
Test for leaks in cooling system using cooling system tester -V.A.G 1274- and adapters -V.A.G 1274/8- and - V.A.G 1274/9-.
