LIQUID FILLING
FOR MACHINES WITH CABS OR FROM N° 139 125
- Reassemble the lower hose 1 (Fig. E4/1).
- Retighten the drain plug 2 (Fig. E4/2) (tightening torque 8 to 12 N.m).
- Slowly fill the circuit with the cooling liquid (see chapter : LUBRICANTS AND
FUEL in the section : 3 - MAINTENANCE) through the filler port 6 (Fig. E4/5).
- Start up the I.C. engine and run at idle.
- Open the cab heater control 7 (Fig. E4/6).
- Loosen the bleed screw 8 (Fig. E4/7) by two turns.
- During the bleeding process, top up the radiator with water.
- Retighten the screw 8 (Fig. E4/7) when the water drained is free of air
bubbles.
HEATING BLEADING
- Maintain the engine at full speed throughout the duration of the bleeding
process.
- During the bleeding process, top up the radiator with water until no air
remains and the water level is stable at the top of the flange of the radiator.
- Fill the expansion pan to 2/3.
- Lift it in order to fill up the hose between the expansion pan and the radiator.
- Check that the level is correct in the expansion pan.
- Close the radiator cap 5 (Fig. E4/5).
- Close the expansion pan cap and put it back onto its support.
- Fill up the expansion pan to the maximum level.
- Allow the engine to run at idle for a few minutes.
- Check for possible leaks.
- Check the level and top up if necessary.
- Reassemble the cover plate 4 (Fig. E4/4).
Note : Heating bleeding is carried out automatically in machines with cabs
and from n° 139 126
The engine does not contain any corrosion resistor and must be filled during the
whole year with a mixture containing 25 % of ethylene glycol-based antifreeze.
