Note:
• HD4X Hybrid OAT coolant, as
supplied by Triumph, is premixed
and does not need to be diluted
prior to filling or topping off the
cooling system.
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.
Coolant Level Inspection
Note:
• The coolant level should be checked
when the engine is cold (at room or
ambient temperature).

To inspect the coolant level:
• Position the motorcycle on level
ground and in an upright position
(not on the center stand). The
expansion tank can be viewed from
the left hand side of the
motorcycle.
• Check the coolant level in the
expansion tank. The coolant level
must be between the MAX and MIN
marks. If the coolant is below the
minimum level, the coolant level
must be adjusted.
Coolant Level Adjustment
Warning
Do not remove the expansion tank cap
when the engine is hot.
When the engine is hot, the coolant
inside the radiator will be hot and also
under pressure.
Contact with this hot, pressurized
coolant will cause scalds and skin
damage.
