Corrosion Inhibitors; Coolant Level Inspection - Triumph Thunderbird Commander Handbook

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.
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
chemicals that are harmful to the human
body. Never swallow anti-freeze or any of
the motorcycle coolant.
Note:
• HD4X Hybrid OAT
supplied by Triumph, is pre-mixed
and does not need to be diluted
prior to filling or topping up the
cooling system.

toxic
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
coolant, as
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.
