OPERATION 56
CHANGE ENGINE COOLANT FILTER/
CONDITIONER
A replaceable coolant filter/conditioner is installed on
the tractor. The filter/conditioner canister contains a
filter element and a conditioner in the form of a paste.
As coolant flows through the filter, the paste
dissolves and mixes with the coolant to provide
optimum engine corrosion protection.
The conditioner in the filter will:
• Increase rust prevention.
• Reduce scale formation.
• Minimize cylinder wall erosion (pitting).
• Reduce foaming of the coolant.
As the conditioner works and protects the system, it
gradually loses its strength and must be replenished.
Replacing the filter at the specified interval ensures
maximum protection.
IMPORTANT: The new filter contains a measured
amount of chemical inhibitor in paste form. The
amount of conditioner and the size of the filter
element are matched to the cooling capacity of the
tractor. It is important that this filter is changed every
1200 hours if total protection of the engine cooling
system is to be maintained. The use of a
non-approved filter may jeopardize this protection.
IMPORTANT: Install a new filter/conditioner in the
event of a large coolant loss such as a failed coolant
hose.
IMPORTANT: Do not replace the filter/conditioner
more frequently than specified unless a large coolant
loss occurs.
IMPORTANT: Anti-leak additives should not be
used. The clogging properties of these additives
could affect the performance of the filter and
conditioner.
IMPORTANT: If it becomes necessary to replace the
filter before the 1,200 hour change interval, or if less
than one-half of the coolant is lost, a filter without a
conditioner should be installed.
IMPORTANT: If replacing with fully formulated
coolant, a coolant filter without the additive should be
used.

CAUTION
Only change the filter when the engine is cool.
To change the filter:
1. Close both shutoff valves, 1.
2. Remove the filter, 2. Dispose of properly.
3. Lubricate the filter seal, 3, on the new filter with
clean oil.
4. Clean the filter manifold sealing surface, 4.
5. Install the new filter until the seal contacts the
manifold. Tighten an additional 1/2 to 3/4 turn.
DO NOT OVERTIGHTEN.
6. Open both shutoff valves.
7. Start the engine and run it for 5 minutes.
8. Check the filter area for leaks.
