Cleaning the Radiator

Coolant (Isuzu Antifreeze/Summer Coolant/Water)

Isuzu recommends Isuzu Antifreeze/Summer Coolant for use in their engines, which can be purchased in concentrate (and mixed with 50% demineralized water) or pre-diluted. See the Isuzu Engine Owner's Manual for further details.

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.

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.

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 10 for engine, radiator, and recovery tank coolant capacities. Make sure the coolant level in the recovery tank is always between the "H" and the "L" markings.

Table 10. Coolant Capacity

Engine and Radiator	1.74 Gal. (6.6 liters)

Reserve Tank	2 Quarts (1.9 liters)

Air Cleaner

Periodic cleaning/replacement is necessary. Inspect it in accordance with the Isuzu 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 Isuzu

Engine Owner's Manual.

The fan belt tension is proper if the fan belt bends 10 to 15

mm(Figure 37) when depressed with the thumb as shown below.

Operation FreezingWeather

When operating in freezing weather, be certain the proper amount of antifreeze (Table 11) has been added.
