Coolant (Ethylane Glycol [Green] / Water — 50/50 mix)
Use only drinkable tap water. If hard water or water with many
impurities is used, the inside of the engine and radiator may
become coated with deposits and cooling efficiency will be
reduced.
An anticorrosion additive added to the water will help prevent
deposits and corrosion in the cooling system. See the engine
manual for further details.
If adding coolant/antifreeze mix to the
radiator, DO NOT remove the radiator cap
until the unit has completely cooled. The
possibility of hot! coolant exists which can
cause severe burns.
Day-to-day addition of coolant is done from the recovery tank.
When adding coolant to the radiator, DO NOT remove the radiator
cap until the unit has completely cooled. See Table 7 for engine
and radiator, coolant capacities. Make sure the coolant level in
the recovery tank is always between the "H" and the "L" markings.
Operation Freezing Weather
When operating in freezing weather, be certain the proper amount
of antifreeze (Table 8) has been added.
Cleaning the Radiator
The engine may overheat if the radiator fins become overloaded
with dust or debris. Periodically clean the radiator fins with
compressed air. Cleaning inside the machine is dangerous, so
clean only with the engine turned off and the
negative
battery
terminal disconnected.
Air Cleaner
Periodic cleaning/replacement is necessary. Inspect it in
accordance with the Perkins, Lombardini or Deutz Engine
Owner's Manuals.
Fan Belt Tension
A slack fan belt may contribute to overheating, or to insufficient
charging of the battery. Inspect the fan belt for damage and wear
and adjust it in accordance with the Perkins, Lombardini or
Deutz Engine Owner's Manuals.
The fan belt tension is proper if the fan belt bends 10 to 15 mm
(Figure 14) when depressed with the thumb as shown below.
Figure 14. Fan Belt Tension
When the antifreeze is mixed with
water, the antifreeze mixing ratio
must be
less than 50%.
NOTE
NEVER
place hands near the belts or fan while the engine is
running.
