Ducati Diavel Service Manual: Changing the coolant
Warning
This operation must only be carried out when the engine is cold.

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.
