Ducati Diavel Service Manual / Engine / Cooling system / Coolant expansion tank / 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).
