Hi everyone......it appears I have a small coolant leak on my 1200S PP that I picked up last week. It has done this same thing after the last 2 rides. Just a small amount but with the current craziness my shop is closed and the shop manual I ordered may take longer than normal to get here. Wondering if this is common. Figure replacing the gasket will be simple but have no idea what is behind the water pump cover. Anyway.....any advice would be appreciated. This is what it looked like after an hour and change ride.....very comfortable bike BTW !!!

Had the same leak on my '12. The only thing behind the water pump cover is the water pump impeller, and a bunch of antifreeze. You might as well go ahead and put on one of the aftermarket pump guards while you have things apart. Might save a ride one day.

Different engines I know, but I had a similar leak on my Monster. The dealer used a Ducati liquid sealant which solved the problem. The bike needed to be completely cool and the sealant needed 24 hours to completely dry before refilling the fluids and starting the engine - bleeding the air etc... The factory is shut down until the end of the month make sure you have all the parts and coolant before you start. Good luck

You can get the shop manual free on-line, here:

It's for a 2010 but will be fine for yours. Its the better version of the manual anyway. Others are all bootleg and chopped to hell and back.

Hope that helps.
Thanks !! That link is awesome!.. The one I ordered is on a disk and is from the same place I got my hyper manual. Looks exactly like this!! Hope the one I ordered is the same!!! It was actually really good once you figure out how to use it z!!

I like Hylomar Blue. It is a non-setting compound good for -50 to +250 degrees C. I use it on gaskets of my older bike, just a very thin film. It makes a great seal, helps hold the gaskets in place while assembling and helps separate casings when disassembling. ThreeBond 1215, the Ducati stuff is the right stuff to use on engine casings and the engine oil strainer plate but is really sticky and messy to clean up. 2017 engine cover bolt torques:

Have you seen large swings in temp recently? I had a similar very small (coin's worth or less) leak similar on my 2012 multi PP when the temp would have big swings. I can't remember the technical explanation but the service tech at my dealership told me it was likely related to the expansion/contraction of some part of the system. Said to check the coolant level and not worry unless it continued into the riding season.

Mine has been rock steady on temps. This does not leak enough to leave coolant on the floor. Just a tiny runner as pictured.

There is no gasket. You need the Ducati sealant which is Three Bond 1215. This stuff is what is used on all mating surfaces on Ducati where a gasket would otherwise go. Search on the web and you should be able to find it. The second best thing would be Yamabond available at Yamaha shops.

Be sure to use the proper coolant. Since there are dissimilar metals the wrong coolant will cause galvanic corrosion. The pink motorcycle coolant is what you need. I use Eni Agip Permanent Spezial. The bolts on the impeller cover are torqued to 10Nm I believe. The drain should be 12Nm. The book says 15 but that doesn’t feel right. Wants to strip.

Look carefully. The leak could be coming from the hose or drain plug and look like it’s the cover. Either one could be a bit loose. Good luck.

The drain plug strips very easily. I followed instructions and with my cheapy torque wrench out of wack an Ooops occurred. Really no need for the drain plug one could seal it up and ride the bike forever using the hose opening... A tempoary fix unless it works...
