Ducati Diavel Service Manual: Checking the coolant level

To the specified intervals in the "scheduled maintenance chart" (sect. 4 - 2) Check the coolant level contained in the expansion reservoir, on the right side of the vehicle.

The coolant level must be between the max. And min marks on the tank.

If the level is low, top up with the recommended coolant.

Remove the filler cap (1) and top up with new coolant to the specified level.

Refit the plug (1).

Checking the coolant level


For optimal operating conditions (coolant mixture starting to freeze at -20 C), the recommended fluid antifreeze should be mixed with water in the following percentages: antifreeze: 35 to 40% of the volume; water: 65 to 60% of the volume.

Important

Very hard water with a high mineral salt content can damage the engine.

Increase the amount of antifreeze to up to 55% volume in the case of very cold climates.

Important

Solutions with less than 30% of antifreeze will not provide sufficient protection against corrosion.

Introduction The engine control system on the diavel uses a sensor that measures air temperature. This sensor has a resistance of ntc type (negative temperature coefficient), that reduces its own value when the temperature increases. The air temperature sensor allows the engine control unit t ...

Changing the engine oil and filter cartridge
Note This operation has to be carried out with hot engine (but turned off) because the oil in these conditions is more fluid and its evacuation is faster and complete. Remove the drain plug (3) with seal (a) from the oil sump and allow the oil to drain off. Warning Dispose of oil and/or fil ...

Cleaning and replacing the spark plugs
Spark plugs are essential to smooth engine running and should be checked at regular intervals. The condition of the spark plugs provides a good indication of how well the engine is running. Have the spark plugs inspected or replaced at a ducati dealer or authorised service centre; they will ...
