I'm guessing this is the culprit. Its on page 111/148 of the parts manual.

55320121A SQUIRTER UNIT $169.86

I had brought my bike to the dealer when I noticed the leak. They checked it out, said they didn't notice any more leaking and its been dry since then.

Is there a service bulletin or anything on it?

I'm enjoying little puddles of coolant that form a couple hours after a ride. Haven't pinpointed exactly where; it all drips from the front of the bellypan because the bike is always parked on a paddock stand.

I'll have them repair it at the 600 mile service.

Little dribble from one of the threaded dowels below the squirter on mine. 400 miles on the clock. C'mon Ducati, get that cooling system straight please, its been over 4 years of the Panigale and why is my '15 leaking from new? Put a service bulletin out if not already. Leading edge production bike should not be leaking from new.

LOL. I would call it more of a heat augmentation system than a cooling system. Reality is this. The Panigale is comprised of a lot of pieces stuffed into a small space and these bikes are very much "assembly line" products. I would bet that most of the issues with the bikes stem from lack of attention to detail in that environment. This thing is not very forgiving with regard to sloppy procedures. That being said. Here are some design problems.
1 the radiator is too small to effectively and efficiently cool a 190hp motor.
2 the fan kicks in too late to catch up
3 the thermostat manifold is cheap thermoplastic unit with a lot of potentially problematic intersections. Assembly integrity in this area is probably hit or miss depending on the day of the week. There are a lot of hose clamps in the system. Additionally, the O rings on the temp sensor either seal it they don't.
4 the water pump gears are some sort of injection molded delrin. The water pump gear undergoes deformation at 218 degrees.
5 the water pump bearing itself is a cheap POS. It is what it is.

I use the MAC 35 mm water only radiator
I manually switch the fan
I use Sacco hoses and stainless smooth bore clamps
I use Petes O ring lube on all the hose connections
I use an aluminum thermostat manifold. It ships with the kits.
I replaced the temp sensor O rings
I replaced the WP bearing with a real one and Check the mesh integrity and alignment of the plastic gears.

Now the bike has a "cooling system" zero leaks, zero heat or reliability issues.
This issue relates to the "loose fastener" thread. You unfortunately should go over your bikes because the guy who built it didn't really give 2 shits about it.

Update, I traced stain back to the weephole so far. Its tiny leak after ride dribbling down to the threaded dowel screw. Still cant tell though if its coming from squirter above or the weephole to be sure. It will have to get much worse to tell. 440 miles on bike, haha. MV has over 6K miles and no issues whatsoever. Boy this sucks.

Love the bike. After I fixed all of issues. That being said, very un impressed with the Ducati from a mechanical engineering perspective. Less with the assembly. Sure looks nice though.

MAC radiator is $1000.00. For me is was a bolt in fit. For another member here, they had some issues. I use a microswitch toggle switch that i just turn on at stop lights. The small parts are available online just about anywhere. Now the "ah ha" moment. I have a machine shop of sorts and access to aerospace materials and metric aerospace parts. I surmise my point is that some of the procedures that I find common may seem like a difficult task if you don't have the facilities to do things. If anyone needs anything made or modified, feel free to shoot me a message. As others here can attest to, I don t charge for stuff (within reason) Sometimes just a slight mod is enough to make a bad situation insignificant.

Where did you get the aluminum thermostat manifold from? or was it custom made?

The cross connect manifold ships with the radiator. H2O and Febur are similar, im sure. The cross connect manifold does not have a thermostat in it. If you want to run the thermostat, you will need to keep the stock manifold.Unless you live in Siberia, having a thermostat on this bike is like putting Oprah on another diet.
