Ducati Diavel Service Manual: Changing the coolant
Warning
This operation must only be carried out when the engine is cold.
Attempting to change the coolant with the engine hot
could lead to burns from hot coolant or scalding steam.
Place a container under the engine and place the motorcycle on its side stand.
Remove the expansion reservoir filler cap (1).
Loosen clip (2), disconnect the hose (3) and drain the coolant inside a container.
Loosen the cap (4) of the fluid exhaust hole placed on the pump cover.
Allow the coolant to drain off completely.
Screw plug (4) with a seal again in the fluid drain hole, and recover the new seal (5).
Tighten the plug (4) to a torque of 20 nm (min. 18 Nm - max. 22 Nm) (sect. 3 - 3, Engine torque settings).
Refill the circuit by pouring new coolant into the circuit via the remote filler cap (6).
Connect the pipe (3) by tightening the clamp (2) to a torque of 1 nm +/-10% (sect. 3 - 3, Frame torque settings).
Allow several minutes for the coolant to fill all the internal passages.
Start up the engine and allow the coolant to reach 110 C; run the engine for about 10 minutes.
Stop the engine and allow it to cool down so that all the air is expelled from the cooling circuit.
Warning
Keep your hands, clothing and tools well clear of the radiator fan at all times; this fan starts automatically without warning and could cause serious injury or damage.
Important
Check the cooling circuit for possible leaks.
Top up the coolant through the expansion reservoir filler to bring the level up to the max. Mark.
Tighten the cap (1) of the expansion reservoir.
Checking the coolant level
To the specified intervals in the "scheduled maintenance chart" (sect. 4 - 2)

Specific operating strategies
Idle speed
No electric motor is used for idle speed regulation (bypass is modulated
instead with the throttle valve), as idle speed
control is effected by the ride-by-wire system. Idle speed is maintained by the
control unit when the speed drops below a
specific threshold and when the clutch ...
Overhaul of cylinder head components
Cylinder heads
Remove any carbon deposits from the combustion chamber and its ducts.
Remove any scale from the coolant ducts.
Check for cracking and inspect the sealing surfaces for scoring, ridges or other
damage.
Check that the cylinder barrel mating surfaces of the cylinder head are ...
