General
A new tool 9814122 for flushing the
cooling system has been introduced.
The tool uses water and compressed
air.
After flushing, the thermostat, all
rubber radiator hoses and the
expansion tank with cover must be
replaced.

Note! The thermostat must be
removed from the thermostat housing
and the thermostat housing reinstalled
for flushing to be effective.
These instructions do not apply to
D4164Tx, D4204Tx and
D5244T10/14/16/19 because the
thermostat cannot be removed from
the thermostat housing.

IMG-333178

3.
The hose that is connected to the
thermostat housing during flushing
must reach outside the engine
compartment.
Tip! Use radiator hoses 30776224 and
30761633 as tools. These are suitable
for the different diameters on the
outgoing connector on the thermostat
housings.

cases, the thermostat must be
removed from the thermostat housing
The following steps show how to do
this.

Flushing cooling system
Connect the cleaning gun to hose (1).
Connect the water hose and
compressed air to the cleaning gun.
Connect a long hose (2) to the
thermostat housing, which extends
outside the engine compartment.
Suggestion: radiator hose 30776224
and 30761633.
Use hot water.
Note! When flushing, the first 20 litres
must be flushed out into a container
because the fluid contains coolant that
must not be flushed out into the
drainage network. Flushing can then
occur over a flush plate with oil
separation.
Flush the cooling system for at least
10 minutes if hot water is used.
If hot water is not available, extend the
time to 20 minutes.

12.
After flushing, the thermostat, all
rubber radiator hoses and the
expansion tank with cover must be
replaced.
For thermostat replacement, see:

coolant, replacement
To replace radiator hoses and
expansion tank, see the spare parts
catalogue for the relevant model and
engine.
There is no method to be followed for
the replacement of radiator hoses and
expansion tank.
