NOTE:

The vehicles, which are using the type D cooling fluid, have a label stacked on the

expansion vessel as follows:

ATTENTION !

Use only cooling fluid type DACIA GLACEOL RX type D.

The D-type antifreeze has a yellow colour.
For the engines variants (with type C antifreeze) it is forbidden the use of type D antifreeze

because the type D antifreeze is damaging the cooper gaskets from the cylinders jackets
lower part and compromising the sealing.

It is forbidden the use of type C antifreeze for the engines with cooling fluid type D.

FILLING AND AERATION OF THE COOLING SYSTEM

Check :

- the tightness of the rings;
- the tightness of the draining plugs from the engine block and from the radiator.

Dismount the radiator plug and mount in its place the MOT 401 filling device.
Completely open the air conditioning radiator tap.
Open the water pump and the air conditioning radiator hose purges.
Fill the expansion vessel 30 mm over the maximum level mark.

Lock the radiator - expansion vessel hose by means of the MOT 453 device.
Pour fluid in the device and fill the radiator and the circuit.
Start the engine ,accelerate it up to about 1500 rpm.
Continue the filling of the circuit till the fluid flows in a continuous jet without air

bubbles, through the aeration purges.
   In this situation,close the two purges.

Dismount the device,fill the radiator and mount the plug.
Dismount the MOT 453 device.
Check the fluid level in the expansion vessel.

COOLING - EXHAUST - FUEL TANK

19 - 3

The cooling circuit is filled with a fluid which ensures the protection against frost,up to

- 40º C.
   The fluid is made up of a mixture of distilled or de mineralised water and antifreeze
fluid as follows:

- for a protection up to - 21º = 35 % concentrate antifreeze fluid + 65 % distilled

water.

- for a protection up to - 40º = 50 % concentrate antifreeze fluid  + 50 % distilled

water.

The protection temperature of the fluid is decreasing in case antifreeze fluid rate is

over 60%.

Remove the radiator plug and take out a certain quantity of the liquid.
Read on densimeter or refractometer scale,the protection temperature of the liquid.
Depending the liquid temperature,perform the necessary corrections as per bellow table:
