F1 - COOLING LIQUID
MT 1030 S Turbo Série 5-E3
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 I.C. engine stopped and cold.
DRAINING THE LIQUID
- Open the I.C. engine bonnet.
- Lift the battery cover. (according to model)
- Place a container under hose 1 (fig. F1/1) on the radiator and drain plug 2 (fig. F1/2) of the
engine block. Remove the hose and loosen the drain plug.
- Remove filling plug 3 (fig. F1/3) of the radiator.
- 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
- Refit and tighten the hose 1 (fig. F1/1) and drain plug 2 (fig. F1/2) (tightening torque 40 N.m).
- Slowly fill up the circuit with cooling liquid (see: 3 - MAINTENANCE: LUBRICANTS AND FUEL) to
the middle of gauge 4 (fig. F1/3) through filler port 5 (fig. F1/3).
- Put back filling plug 3 (fig. F1/3).
- Run the I.C. engine at idle for a few minutes.
- Check for any possible leaks.
- Check the level and refill if necessary.
The I.C. 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.

NOTE: When opening the evaporator unit, remember to replace the cover seal.
CAUTION: DO NOT ATTEMPT TO REPAIR ANY PROBLEMS YOURSELF. ALWAYS REFER TO YOUR DEALER WHEN
REFILLING CIRCUITS, AS THEY HOLD THE CORRECT SPARE PARTS, AS WELL AS HAVING THE NECESSARY
TECHNICAL KNOWLEDGE AND TOOLS.
- Do not open the circuit under any circumstances as this would cause the coolant to be lost.
- The cooling circuit contains a gas which can be dangerous under certain conditions. This gas, coolant R 134a, is colourless, odourless and
heavier than air.
• If this gas is inhaled, take the victim into fresh air, give oxygen or artificial respiration if necessary and call a doctor.
• If the gas is in contact with the skin, wash it immediately under running water and remove any contaminated garments.
• If the gas is in contact with the eyes, rinse them in clear water for 15 minutes and call a doctor.
- The compressor has an oil level gauge (fig. F2). Never unscrew this gauge because it would depressurizes the installation. The oil level is
only checked when changing the oil in the circuit.
