5. Oil Cooler and Cooling Fan
Oil returning from the control valve is circulated through
the oil cooler before being sent to other parts of the
hydraulic system.
An engine cooling fan drives air through the oil cooler
when the rear door is closed. Refer to Figure 4.7E.
The oil cooler should be checked daily for dirt buildup on
the cooling fins. If the air flow is restricted through the
cooling fins, overheating of the hydraulic system may
occur. Clean any dirt buildup with compressed air. Figure
4.7E shows the radiator setup for the loader.
