Pour in coolant and bleed cooling system

 Warning

Risk of injury to skin and eyes suffering scalding from contact with hot coolantspray. Risk of poisoning from swallowing coolant.

Do not open cooling system unless coolant temperature is below 90 °C. Open cap slowly and release the pressure. Do not pour coolant into beverage containers.
Wear protective gloves, protective clothing and safety glasses.

1

Remove cap at coolant expansion reservoir (1).

2

 Tighten tester cap (4) (124 589 00 91 00) or  tester cap (4) (169 589 00 91 00) at coolant expansion reservoir (1).

 Engine 646 in model 909
with code MS9 (Engine version Euro 4) Use tester cap (4) (124 589 00 91 00).

 Engine 646 in model 909
with code MP5 (Engine version Euro 5) Use tester cap (4) (169 589 00 91 00).

3

 Fit vacuum-type cooling system filler (5) onto  tester cap (4) (124 589 00 91 00) or  tester cap (4) (169 589 00 91 00).

4

Fit venturi nozzle (5.5) onto  vacuum-type cooling system filler (5).

5

Close drain valve (5.1) and feed valve (5.2).

6

Prepare indicated   coolant volume in the specified composition and fill into coolant reservoir of  vacuum-type cooling system filler (5).

 To prevent air from being drawn in, ensure that the coolant reservoir contains more coolant than the maximum filling capacity of the engine cooling circuit.

7

Fit feed hose (5.3) to coolant reservoir of the  vacuum-type cooling system filler (5).

8

Attach waste air hose (7) in an empty, suitable container.

9

Connect compressed air hose (6) to the Venturi nozzle (5.5) and apply compressed air.

10

Open drain valve (5.1).

 A vacuum is created in the engine cooling system.

11

Open feed valve (5.2) until feed hose (5.3) has filled with coolant.

12

Close drain valve (5.1) when the vacuum display (5.4) is in the green range.

13

Disconnect compressed-air hose (6) from Venturi nozzle (5.5) and check whether vacuum remains stable for 30 s.

If vacuum does not remain stable,



check hoses and connections, eliminate leaks and again generate a vacuum.

14

Open feed valve (5.2).

 The engine cooling system is filled.

15

Open drain valve (5.1) when no more coolant is drawn in from the coolant reservoir of the  vacuum-type cooling system filler (5).

16

 Remove vacuum-type cooling system filler (5) with all connections and  tester caps (4) (124 589 00 91 00) or  tester cap (4) (169 589 00 91 00).

17

Correct coolant level in coolant expansion reservoir (1).

18

Tighten cap on coolant expansion reservoir (1).
