4. Open supply and return hoses at radiators. Do this by pulling off the spring clips for the two Henn couplings -1- and pulling the hoses away from
the coolant pipes -2-. Collect coolant in a clean container. Insert the clips in the correct position in the connectors and connect the hoses. The
connection should audibly snap into place. Check correct positioning once again by pulling on the hoses.
5. Remove heating hoses on underside of car. Secure the pipes with hose clips and then open the spring band clamps. Remove both hoses and slowly
open hose clamps. Allow coolant to drain into a clean container. Clean hoses, stick them back and attach the clips. Check that the hoses are firmly
in place.
Filling with coolant
Filling coolant (includes bleeding)
Note: The process of filling and bleeding the cooling system continues to be performed using the special tool Radiator filling device 9696.
Note:
^
If a vacuum does not build up, there is a leaking valve in the coolant circuit.
^
Deformation of the rubber hoses of the cooling system is normal.
^
When the pressure gauge pointer is in the green area of the display scale, a sufficient vacuum has been built up.
^
After both shutoff valves on the vacuum pressure gauge have been closed and the compressed air supply has been disconnected, the vacuum must
not drop. If the vacuum drops within approx. 30 seconds, there is a leak in the coolant circuit.
