Servicing the Engine Cooling
System
Remove debris from the oil cooler and radiator daily. Clean
them more frequently in dirty conditions.
This machine is equipped with a hydraulically driven fan drive
system that automatically (or manually) reverses to reduce
radiator and screen debris build-up. While this feature can
help reduce the time required to clean radiators and coolers,
it does not eliminate the need for routine cleaning. Periodic
cleaning and inspection of the radiator is still required.
1. Turn the engine off and raise the hood. Clean the
engine area thoroughly of all debris.
2. Remove the knobs (Figure 67) securing the oil cooler
to the frame.

3. Pivot the oil cooler rearward. Clean both sides of the
oil cooler and radiator area (Figure 68) thoroughly with
compressed air. Start from the front and blow the
debris out towards the back. Then clean from the back
side and blow towards the front. Repeat procedure
several times until all chaff and debris is removed
Important: Cleaning the radiator or oil cooler
with water can promote premature corrosion and
damage to components.
