Day-to-day addition of coolant is done from the
Day-to-day addition of coolant is done from the reserve tank.
When adding coolant to the radiator, DO NOT remove the
radiator cap until the unit has completely cooled. See Table
12 for engine, radiator, and reserve tank coolant capacities.
Make sure the coolant level in the reserve tank is always
between the "H" and the "L" markings.
CAUTION :
When adding coolant or antifreeze to the
radiator, do not remove the radiator cap
until the unit has completely cooled.
Operation in Freezing Weather
When operating in freezing weather, be certain the proper
amount of antifreeze (Table 13) has been added.

CAUTION
:
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
battery disconnected.
Air Cleaner
Periodic cleaning/replacement is necessary. See
maintenance section for instruction to cleaning/replacing air
cleaner.
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. See maintenance section on replacing
belts. To adjust tension:
1. Insert a bar between alternator and the cylinder block to
fix alternator in position. When fixing the alternator in
position, insert a wooden block between the bar and
alternator to prevent damage to the alternator.
2. Loosen bolts and nuts located on the alternator.
3. Move alternator with the bar so the deflection of the belt
is approx. 8mm.
4. Tighten the bolt and nuts to fix the alternator back to
position.
The fan belt tension is proper if the fan belt bends 7 to 10
mm (Figure 40) when depressed with the thumb as shown
below.
Figure 40. Fan Belt Tension
Never place hands near the belts or fan
while the generator set is running.
