Mod. Apollo
- ATTENTION: - Read the SAFETY REGULATIONS (contained in this manual) carefully for the safety of all personnel and your vehicle.
RADIATOR WATER / OIL / INTERCOOLER
- ATTENTION -
These operations must be carried out when
the engine is cold.
Radiator grill cleaning
Radiator grills (fig.24/D Pos.”1”, fig.25 /D Pos.”1”), en-
gine fan (fig.25/D Pos. “2”) and air recirculation networks
(g.26/D Pos.”A-B-C-D”) must be kept as clean as possible
to allow for maximum heat exchange between the radiator
and the circulating air. To remove impurities, use a low pres-
sure air jet directing it from the inside towards the outside.
Then pass the jet of air on the inner parts covered with dirt.
If dirt is particularly compact, soften it with a low pressure
water jet before using the air.
- ATTENTION:
Consult the engine operation and maintenance handbook
before using jets of air or water.
- ATTENTION:
Heat exchange flaps are very delicate. Do not use rags or
brushes to clean them. Jets of water and air must be di-
rected horizontally.
Cooling liquid level check
During normal vehicle use, the water level should be at 3 cm
under the radiator cap (g.24/D Pos.”2”).
Verication of the correct level of cooling liquid must be car-
ried out as follows:
1. Stop the vehicle on a at surface.
2. Switch off the engine and remove the ignition key, hang up
a sign in the cab that reads “maintenance work under way”.
3. Slowly turn the radiator cap (fig.24/D Pos.”2”) counter-
clockwise until reaching the safety pin.
4. Discharge pressure and steam.
5. Remove the cap.
6. Check the coolant level. If necessary, top up using a mix-
ture of water and antifreeze.
7. To reinsert the cap follow these steps in the opposite order.
- ATTENTION:
If frequent top ups are necessary in normal working condi-
tions, verify that there are no cooling system leaks. Contact
a DIECI after-sales centre if problems arise.
- ATTENTION -
Use demineralised water to ll the cooling system. Cal-
careous water may cause incrustations and premature
system ageing.
