COOLANT
WATER & ANTI-FREEZE:
Please refer to the Fluids section for complete information.
WATER BOILER:
A water boiler can be connected to the engine coolant
circuit. If the boiler is located above the engine, an
additional recovery tank must be installed above the
boiler.
Ducts to the boiler must be in accordance with high
temperature and high pressure. Do not use flexible hoses
supplied from a general hardware store.
A specific boiler kit is available from Nanni Industries.
Please contact your nearest Nanni representative for
more information.
The amount of coolant must be adapted depending
the model of water boiler to completely fill the coolant
system.
COOLANT EXPANSION:
When the engine is running, the internal temperature is
high ; as a result, the coolant liquid expands its volume.
The heat exchanger is designed to accomodate this
normal and physical expansion.
Make sure not to overfill the heat exchanger when filling
with coolant.
COOLANT LEVEL
DANGER !
Never open the coolant filling cap or any plug of the
cooling system when the engine is operating or still
warm. Steam or hot fluid can spray out. Prevent potential
injuries !
Check the coolant level before starting the engine.
1. Stop the engine and remove the key from the panel.
2.
Unscrew the filler cap (
A
) on the exchanger tank on
picture below.
3. You may top-up with clean water only, if amount to
fill is very remote. Use glycol mix if tank is almost
empty.
4.
Stop filling when level is at bottom lip of the cap filler.
NOTE !
This Max level in the tank is representing the effective
level of coolant only when the engine is cold.
