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.
WARNING - BURN HAZARDS
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.

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 Volvo Engine Owner's Manual.
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 Volvo
Engine Owner's Manual.
The fan belt tension is proper if the fan belt bends 10 to 15
mm(Figure 38) when depressed with the thumb as shown below.

CAUTION - ROTATING PARTS
NEVER place hands near the belts or fan while the generator set is running.
