OPERATION 60
CHANGE ENGINE COOLANT AND
FILTER/CONDITIONER
The rust and corrosion inhibitors in the antifreeze and
the filter/conditioner deteriorate with use and require
replacement on a regular basis.
The tractor is equipped with a water filter with coolant
conditioner. The water filter/conditioner removes
foreign material from the cooling system, controls
rust, and conditions the coolant to prevent erosion
and cavitation in the cooling system.
See “Operation 56” for additional information on the
filter/conditioner.
WARNING
The coolant system operates under pressure
which is controlled by the radiator pressure cap.
It is dangerous to remove the pressure cap while
the system is hot. When the system has cooled,
use a thick cloth and turn the cap slowly to the
first stop and allow the pressure to escape before
fully removing the cap. Coolant should be kept
off the skin. Adhere to the precautions outlined
on the antifreeze and inhibitor containers, where
used.
CAUTION
Drain the coolant when the engine is cool.
Park the tractor on level ground and engage the park
brake and block the wheels front and rear.
To change coolant and the filter/conditioner:
1. Turn the heater control knob to the maximum
position.
2. Check that the heater shutoff valves, 1, are open.
