These operations are to be carried out if necessary or every two years at the beginning of winter.
Place the lift truck on level ground with the engine stopped and cold.
DRAINING THE LIQUID
- Raise the engine cover (see: 2 - DESCRIPTION: INSTRUMENTS AND CONTROLS).
- Open radiator drain valve 1 (fig. F1/1).
- Undo engine block drain plug 2 (fig. F1/2).
- Remove expansion tank filling plug 3 (fig. F1/3) and empty the tank.
- Remove radiator filler cap 4 (fig. F1/4).
- Let the cooling circuit drain entirely while ensuring that the ports do not get clogged.
- Check the condition of the hoses as well as the fastening devices and change the hoses if
necessary.
- Rinse the circuit with clean water and use a cleaning agent if necessary.
FILLING THE LIQUID
- Close radiator drain valve 1 (fig. F1/1).
- Retighten engine block drain plug 2 (fig. F1/2).
- Remove bleeder screw 5 (fig.F1/5).
- Slowly fill the circuit with the cooling fluid (see: 3 - MAINTENANCE: LUBRICANTS AND FUEL)
through the filler port 6 (fig. F1/4).
- Replace bleeder screw 5 (fig.F1/5) when the liquid comes out of this hole.
- Refit radiator filler plug 4 (fig. F1/4).
- Fill the expansion tank to the maximum level through the filler port 7 (fig. F1/3).
- Run the engine at idle for a few minutes.
- Check for any possible leaks.
- Check the level and refill if necessary.
- Refit expansion tank filler plug 3 (fig. F1/3).
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.
