Evaporative Canister - under the airbox.
Purge Control Valve - (electronically controlled by the engine ECM) left hand side of the airbox behind the side panel.
- Evaporative canister
- Purge valve
When the engine is stationary, any pressure increase in the fuel tank due to a rise in ambient temperature will cause the fuel vapour to pass down the breather pipe A to a carbon filled evaporative canister that stores the vapour.
Once in the canister, vapour cannot return to the fuel tank because the purge valve is closed.
- Breather pipe A
- Evaporative canister
- Purge valve
When the engine is started, a vacuum is applied to the purge hose from the inlet manifold.
At certain times, the engine ECM opens the purge valve. The vacuum applied to the purge valve now begins to draw stored vapour from the carbon filled evaporative canister and returns it to the inlet manifold for burning in the engine.
In order to control the speed at which vapour is purged from the canister, the engine management system regularly shuttles the purge control valve between open and closed positions.

Check the radiator hoses for cracks or deterioration, and hose clamps for tightness in accordance with scheduled maintenance requirements.
Radiator
CAUTION
Using high pressure water, such as from a pressure-washer, can damage the radiator fins and impair the radiator's efficiency.
Do not obstruct or deflect airflow through the radiator by installing unauthorised accessories in front of the radiator or behind the cooling fan. Interference with the radiator airflow can lead to overheating and consequent engine damage.
1. Check the radiator for stone damage.
2. Check the radiator core for damage to fins or obstructions to air flow.
3. Clean off any obstructions with a stream of low-pressure water.
CAUTION
To avoid overheating and consequent engine damage, replace the radiator if the cores are blocked or if the fins are badly deformed or broken.
4. Rectify any damage.
Cooling Fan
WARNING
The cooling fan is switched on and off by the Engine Control Module in response to a signal received from the coolant temperature sensor. To prevent injury, never place loose clothing, fingers or hands near the cooling fan, until the engine is stopped. Loose clothing, fingers or the hands could become trapped during cooling fan operation and cause crushing injury to the fingers, hands or other parts of the anatomy.
The motorcycle is fitted with a thermostatically controlled electric fan situated behind the radiator. When the fan operates with the motorcycle stationary or at slow speed, cool air is drawn through the radiator from the front of the motorcycle.
1. Check that the cooling fan spins freely and without tight spots.
2. Check the cooling fan blades for signs of heat distortion.
3. Rectify as necessary.
A year-round, Hybrid Organic Acid Technology (known as Hybrid OAT or HOAT) coolant is installed in the cooling system when the motorcycle leaves the factory. It is coloured green, contains a 50% solution of ethylene glycol based antifreeze, and has a freezing point of -35ºC (-31ºF).
Always change the coolant at the intervals specified in the Scheduled Maintenance chart.
WARNING
The standard coolant mixture contains toxic chemicals that are harmful to the human body. Never swallow neat antifreeze or any of the coolant mixture.
CAUTION
The antifreeze incorporated in the coolant mixture contains a corrosion inhibitor that helps prevent damage to the cooling system and engine. Without this inhibitor, the coolant would 'attack' the metals and the resulting corrosion would cause blockages in the cooling system leading to engine overheating and damage.
Always use the antifreeze listed in the Specification section and never use a methanol based antifreeze as this does not contain the required corrosion inhibition properties.
Note
HD4X Hybrid OAT coolant, as supplied by Triumph, is premixed and does not need to be diluted prior to filling or topping up the cooling system.
CAUTION
If hard water is used in the cooling system, it will cause scale accumulation in the engine and radiator and considerably reduce the efficiency of the cooling system.
Reduced cooling system efficiency may cause the engine to overheat and suffer severe damage.
WARNING
Before starting work, ensure the motorcycle is stabilised and adequately supported. This will help prevent it from falling and causing injury to the operator or damage to the motorcycle.
WARNING
Do not remove the coolant pressure cap when the engine is hot. When the engine is hot, the coolant inside the radiator is hot and also under pressure. Contact with hot coolant will cause scalds and skin damage.
Note
- Prior to disassembly of the coolant hoses, note the orientation and position of the hose clamps to help ensure that they are returned to the same positions and orientation on assembly.
- Use T3880207 - Hose Clip Pliers for removal and installation of the hose clamps.
Perform the following operations:
- Seat - Removal
- Battery - Removal
- Fuel Tank - Removal
1. Remove the coolant pressure cap.
- Coolant pressure cap
2. Position a container below the engine and radiator to collect the displaced coolant.
3. Using T3880207 - Hose Clip Pliers, release the hose clamps then release the bottom hose from the radiator and allow the coolant to drain.

4. Disconnect the bottom hose.
WARNING
Before starting work, ensure the motorcycle is stabilised and adequately supported. This will help prevent it from falling and causing injury to the operator or damage to the motorcycle.
WARNING
Do not remove the coolant pressure cap when the engine is hot. When the engine is hot, the coolant inside the radiator is hot and also under pressure. Contact with hot coolant will cause scalds and skin damage.
1. Refit the bottom hose. Ensure the hose is positioned to the alignment mark and the clamp is positioned as noted for removal.

2. With the aid of an assistant, raise the rear wheel until the filler opening is above the radiator's upper coolant tank.
- Filler opening
- Radiator's upper coolant tank
3. Slowly add coolant mixture to the system, through the filler opening, until coolant escapes from the filler opening.
Note
If the system has filled correctly and fully, there should be coolant visible through the filler opening.
Note
During filling, squeezing the bottom hose with both hands will help to pump coolant around the system and remove trapped air.
4. Refit the coolant pressure cap.
5. Lower the motorcycle's rear wheel to the ground.
6. Refit the fuel tank (see Fuel Tank - Installation).
7. Reconnect the battery, positive (red) lead first and tighten the battery terminals to 4.5 Nm.
8. Start the motorcycle and allow the engine to idle. Briefly raise the engine speed several times to allow any air to be expelled from the system.
9. Stop the engine and allow it to cool.
10. With the aid of an assistant, raise the fuel tank to allow access to the coolant pressure cap.
11. Remove the coolant pressure cap.
12. If necessary, top up the system through the filler.
13. Refit the coolant pressure cap.
Perform the following operations:
- Fuel Tank - Installation
- Check the expansion tank level and top up if necessary (see Coolant Level Inspection).
- Seat - Installation
WARNING
Before starting work, ensure the motorcycle is stabilised and adequately supported. This will help prevent it from falling and causing injury to the operator or damage to the motorcycle.
Note
The oil pump and water pump are supplied as an assembly and cannot be separated. For additional information, refer to Oil Pump (see Oil and Water Pump - Removal for removal and Oil and Water Pump - Installation for installation).
1. Check the water pump face and shaft seals for signs of leakage. Renew the pump if leakage is evident.
