I've drained the coolant via the drain screw on the water pump housing, and I'm about to replenish the system with fresh coolant. The owners handbook says that the cooling circuit capacity is 3.3 liters -- is that correct?

Thanks,

The handbook says 3.3 litres.
Really, I didn't manage to put all those 3.3 litres of coolant into the circuit.
No matter, you have to fill the circuit until the reservoir is full.
But, you need to unscrew the reservoir screws and keep the reservoir so it becomes higher than the rest of the circuit.
Later, you have to drain the circuit by the screw on the water pump, so that all the air bubbles go out.

francesco mean to say that some air bubble can happen so remain inside the water pump.
You should loose a bit the bleeding screw on the pump aluminium body to let the air flow away

Thanks -- that's easy -- will do --

Don't worry.
You have kept most of the air out.
If you still have some air in the circuit you will only see that the coolant will lower a bit into the reservoir after the engine have run.
In fact, when the coolant is replaced, it needs to run the engine to be sure having the air out.

Thanks -- I feel better now!

It could take a couple of heat up and cool down cycles to get all the air out,don't worry just keep an eye on the coolant bottle.

Thanks. This Ducati is making a mechanic out of me, fer sure. I thought I was one already, but this is a whole 'nother world.

We'll have balmy weather again by Monday (after a deep freeze tomorrow), so I'll start 'er up again then. Would go for a ride, but the rear shock is at the suspension specialist. Long story. For another post ... .
