Leon Mk1

Filling: only using the cooling system fillerVAS 6096
Filling: only using the cooling system filler -VAS 6096-
l  Cooling system is leak tight
   
–  Fill coolant reservoir of -VAS 6096- with at least 8 litres of pre-mixed coolant in correct mixture ratio:
–  Screw adapter for cooling system tester -V.A.G 1274/8- into coolant expansion tank.
–  Attach cooling system charge unit -VAS 6096- to adapter -V.A.G 1274/8-.
–  Run vent hose -1- into a small container -2-.
  Note
The vented air draws along a small amount of coolant, which should be collected.
–  Close both valves -A- and -B- (turn lever at right angles to direction of flow).
–  Connect hose -3- to compressed air.
l  Pressure: 6 ... 10 bar of pressure

–  Open valve -B- by setting lever in direction of flow.
l  The suction jet pump generates a partial vacuum in the cooling system; the needle on the gauge should move into the green zone.
–  Also briefly open valve -A- (turn lever in direction of flow) so that hose on reservoir of -VAS 6096- can fill with coolant.
–  Close valve -A- again.
–  Leave valve -B- open for another 2 minutes.
l  The suction jet pump continues to generate a partial vacuum in the cooling system; the needle on the gauge should remain in the green zone.
–  Close valve -B-.
l  The needle on the gauge should stop in the green zone. The vacuum level in the cooling system is then sufficient for subsequent filling.
  Note
t  If the needle does not reach the green zone, repeat the process.
t  If the vacuum drops, the cooling system must be checked for possible leakages.
–  Pull out pressure hose.
–  Open valve -A-.
l  The vacuum in the cooling system causes the coolant to be drawn out of the reservoir of -VAS 6096-; the cooling system is then filled.
–  Detach cooling system charge unit -VAS 6096- from coolant expansion tank.

–  Top up coolant to „max“ mark.
–  Close expansion tank.
–  Start the engine. Let the engine run for about 3 minutes at approx. 2000 rpm.
–  Then run engine at idling speed until radiator fan cuts in.
–  Check coolant level and top up any missing coolant, if necessary. When the engine is at normal operating temperature, the coolant level must be at the top mark, and when the engine is cold, in the middle of the shaded area.
