AS00.00-Z-0005-01A

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.

Flush without a cleaner

1

Start engine and bring to operating temperature

Coolant temperature approx. 80 °C.

2

Switch off engine and allow to cool off for approx. 30 min

So that any oil present settles in the expansion reservoir.

3

Check whether there is oil is in the coolant expansion reservoir

If there is oil in the coolant expansion reservoir.

Suction off coolant/oil mixture from coolant expansion reservoir and dispose of in an environmentally compatible manner.

4

Drain off coolant completely

AR20.00-G-1142H

5

Remove coolant expansion reservoir

6

Disconnect feed hose and return hose of the heater

Only for engine with heating system.

7

Flush heater with fresh water

Only for engine with heating system.

If possible use hot or warm water.
Dispose of rinsing water in an environmentally friendly way.

8

Attach feed hose and return hose of the heater again

Only for engine with heating system.

9

Separate coolant hoses at interfaces between engine and cooler

10

Flush out engine and cooler with fresh water

If possible use hot or warm water. Dispose of rinsing water in an environmentally friendly way.

11

Attach coolant hoses to interfaces between engine and radiator

Remove oil

12

Install opened coolant thermostat

AR20.10-G-2460H

Open coolant thermostat for oil removal

WF58.50-G-2003-01H

Both cooling circuits are flushed via installation of opened coolant thermostat.

13

Mix a 3% cleaning solution of the mild-alkali cleaner and fresh water


The cleaning solution must be mixed outside both cooling circuits.
Filling in cleaner directly damages parts of engine cooling system.

Mixing ratio: 30 ml cleaner to 1 l fresh water.
Dispose of cleaning solution in an environmentally acceptable manner.

14

Flush out coolant expansion reservoir with the 3­percent cleaning solution

15

Install coolant expansion reservoir

16

Fill engine cooling system with 3-percent cleaning solution

17

Set heater to maximum heat output

Only for engine with heating system.

18

Start the engine and allow to warm up a 60 °C coolant temperature; hold at this coolant temperature for about 5 min

If necessary, cover radiator to achieve coolant temperature of 60 °C.

19

Switch off engine and allow cooling system to cool down to about 50 °C

20

Drain cleaning solution completely from the engine cooling system


Flush engine cooling system at least 2 times with fresh water immediately after de-oiling.
Residual quantities of cleaning solution damage parts of engine cooling system.

Dispose of cleaning solution in an environmentally acceptable manner.

Flush after deoiling

21

Flush engine, radiator and if necessary the heating with fresh water

To flush with fresh water, perform operation steps 6 to 11.
Dispose of rinsing water in an environmentally friendly way.

22

Fill and flush engine cooling system with fresh water at least 2 times


Fill engine cooling system with coolant immediately after last flushing process.
Water in the engine cooling system leads to corrosion.

Allow engine to run for approx. 5 min during each flushing process.

23

Check flushing water of last flushing process for oil drag-in

If oil is still present in flushing water, repeat de-oiling.

Perform work from operation step 16.

24

Check flushing water of last flushing process for acid content with a test strip

Test strips show the pH value.

If flushing water of last flushing process does not have neutral pH.

Repeat engine cooling system flushing with fresh water once.


Fill engine cooling system with coolant immediately after last flushing process.
Residual quantities of flushing water lead to corrosion on parts of engine cooling system.

25

Replace an opened coolant thermostat by the previously removed coolant thermostat

AR20.10-G-2460H

Clean coolant thermostat before installation.
