Maintenance and Adjustment
Corrosion Inhibitors
To protect the cooling system from corrosion,
the use of corrosion inhibitor chemicals in the
coolant is essential.
If coolant containing a corrosion inhibitor is
not used, the cooling system will accumulate
rust and scale in the water jacket and radiator.
This will block the coolant passages, and
considerably reduce the efficiency of the
cooling system.
Note:
• HD4X Hybrid OAT coolant, as
supplied by Triumph, is pre-mixed
and does not need to be diluted
prior to filling or topping up the
cooling system.
Coolant Level Inspection
1. Final drive belt cover
2. Expansion tank
3. MAX mark
4. MIN mark
Position the motorcycle on level ground and
in an upright position.
The coolant level within the expansion tank
can be inspected without removing any
covers. The expansion tank can be viewed
from the right hand side of the motorcycle,
through a window in the rear of the final
drive belt cover.
Check the coolant level in the expansion
tank. The coolant level must be between the
MAX (upper line) and MIN (lower line)
marks. If the coolant is below the minimum
level, the coolant level must be adjusted.
Warning
HD4X Hybrid OAT coolant contains
corrosion inhibitors and anti-freeze suitable
for aluminium engines and radiators.
Always use the coolant in accordance with
the instructions of the manufacturer.
Coolant that contains anti-freeze and
corrosion inhibitors contains toxic
chemicals that are harmful to the human
body. Never swallow anti-freeze or any of
the motorcycle coolant.
