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. Expansion tank
2. MAX mark
3. MIN mark
To inspect the coolant level:
Position the motorcycle on level ground
and in an upright position.
Check the coolant level in the expansion
tank by looking up, through the centre
opening of the front fairing.
The coolant level should be between the
MAX and MIN marks.
If the coolant is below the minimum level,
the coolant level must be adjusted.
HD4X Hybrid OAT coolant contains
corrosion inhibitors and antifreeze
suitable for aluminium engines and
radiators. Always use the coolant in
accordance with the instructions of
the manufacturer.
Coolant that contains antifreeze and
corrosion inhibitors also contains toxic
chemicals that are harmful to the
human body. Never swallow antifreeze
or any of the motorcycle coolant.
