Ducati Diavel Service Manual: Refitting the cooling system hoses and unions

Position the pump/radiator sleeve (22) and the radiator/radiator sleeve (23).

Fit sleeve (23) and sleeve (22) to their corresponding fittings (n) and (o), and bring them fully home on collars (p).

Note

Sleeves (23) and (22) must be oriented so that the grooves (q) match the tabs (r) on fittings (n) and (o).

Insert the clip (21) on sleeve (23) and the clip (21) on sleeve (22), bringing them to the position of the white marks (s) on the sleeves.

Orient the clamps (21) as shown and tighten them to a torque of 2.5 Nm +/- 10% (sect. 3 - 3, Frame torque settings).

Tighten the clamps (21) to a torque of 2.5 Nm +/- 10% (sect. 3 - 3, Frame torque settings).

Install one gasket (31) into the seat of the vertical head fitting (33).

Fix the fitting (33) on the vertical head by means of the screws (32) with prescribed threadlocker, and tighten them to a torque of 6 nm (min. 5 Nm - max. 7 Nm) (sect. 3 - 3, Engine torque settings).

Place the breather pipe (27) on the half-casing fitting and tighten the clip (28).

If removed, fit the coolant union (36) on the horizontal cylinder head and tighten it to a torque of 20 nm (min. 18 Nm - max. 22 Nm) (sect. 3 - 3, Frame torque settings).

Assemble the thermostat (38) - thermostat/head sleeve (35) assembly by coupling and tightening them to a torque of 2.5 Nm +/- 10% (sect. 3 - 3, Frame torque settings) - and the thermostat/head sleeve (37) - radiator/thermostat sleeve (40) by tightening the clamps (21) and (34).

Place breather pipe (30) on the vertical head and tighten the clip (28) to a torque of 2.5 Nm +/- 10% (sect. 3 - 3, Frame torque settings).

Fit the clamp (34) on the union (33) matching to dots.

Position the thermostat unit (38) - thermostat/head sleeve (35) - thermostat/head sleeve (37) with the clips (34) and tighten the clips (34) to a torque of 2.5 Nm +/- 10% (sec. 3 - 3, Frame torque settings).

Fix the breather pipe (26) to the radiator/plug sleeve (24) and to the left radiator by tightening the clips (25) and (43) to a torque of 1 +/- 10% (sect. 3 - 3, Frame torque settings).

Position the radiator/thermostat sleeve (40) with the clips (21) and the radiator/plug sleeve (24) on the radiators and tighten the clips to a torque of 2.5 +/- 10% (Sect. 3 - 3, Frame torque settings).
