Leaking coolant from the back of engine

Back of my engine is leaking a bit of coolant. This is what it looks like after 20 minutes riding. The zzzzz stops after 5 minutes parking though. Do you guys think this will be expensive to fix?

first step: take off the side fairings and check all water hose clamps, they tend to loose themself.
second step: clean your bike, take a ride (I do it w/o the fairings) and visually try to locate a leak afterwards.

I saw the leak. It's right there on that area. There are bubbles coming out for about 5 minutes after ride.

Out from the engine (I mean from between the the engine block's sealing surfaces)?

I've had a leak there before but it was weeping quite a bit of oil from the seal. My bike had maybe 4 or 5k miles I don't recall. Ducati informed my mechanic he had to tear the engine apart, clean everything up and re-seal. It was a HUGE job and I didn't have the bike for a few weeks.

Shoot.... Ah Well it just has to be done i guess

Having the same problem.

thermostat housing - i've replaced 2

if however the coolant is leaking from the tiny weep hole seen from left side of motorcycle above the generator, and under the thermostat housing, then it would be a water pump problem

I know this is a really old thread but I am having the same problem where coolant is leaking from the engine casing in the rear, same spot Marmoot showed in this pic! Anyone else have this problem and any recommendations on how to fix?

I would recommend inspection

Determine what is leaking and THEN research the best fix : )

Thanks Don and this is why I responding to this specific thread hoping others like marmoot would let me know how they resolved there issue. I've been doing a bunch of research and mines in the exact same spot (rear engine right where the casing comes together in the back). I have cleaned the area and then started and you can see that area right in the back fill up with coolant. It's seeping right out at the seam but just in that one tiny spot. It sounds like a few others had similar issues and was hoping to hear how others have resolved that specific issues?

Seth, I’m curious what year and model Ducati you have. Thank you.

Superquatro can only leak coolant from 2 places back there. Head gasket or the parting line for the cases. What year is the bike? How many miles are on it? How often did the coolant get drained and refilled?

If it is the V head gasket it’s still a huge job, but if the cases have to be split because acidity or ph ate the silicone man oh man. Bummer

Don and JDJ thank you both as I really appreciate any input and guidance...I am kinda freaking out. I just got the bike unfortunately and am coming from long time Japan bikes (Suzuki and Kawasaki) so this is my first experience with Ducati. It's a 2012 1199-panigale with 16,000. I ran the VIN so it's clear and I'm the 3rd owner. I researched before I bought it and thought everything was good, the seller even should me he had all the Desmo 15k maintenance done and the bike runs good but I can't tell you how frequently it was serviced. For coolant it's got engine ice that is blue and it's clean. After my first ride I noticed coolant gathering in that area in the rear right under the rear exhasut port (exact same spot as the 1st pic in this thread). I was originally thinking head gasket but clean the area and tested it and you can see it gathering right at the casing seam and the head gasket is still dry. I've got a video of it and could email it to someone if helpful. I also noticed there is what looks like a small crack line in the casing in right by the seam but it looks like the coolant is coming from the seam. Hope this helps and let me know if I can any other helpful info or if you have advice on what to do next?

Shoot it

Okay, just sent via email!

There is the same amount of coolant visible at the the beginning of the vid and 45 seconds later at the end. Can you take a rag and wipe it off and some brake clean and spray it and wipe it off again and make another video?

Also if you double tap the area you want it to focus on it will improve focus : )

By the looks of that video, that’s coming from the case. That’s like an IRS audit followed by divorce court followed by a root canal followed by a head on collision on the way home.

Here are photos of both case halves where the leak is coming from. There are no water passages where the leak is coming from. That area is where the gearbox is and that’s oil so if that’s coolant, it’s coming from somewhere else. It just happens to be exiting at that spot. Case needs to come apart.

That’s what I told him in email

His crack:



That is a boss for a case bolt

Nothing is gonna leak outta there cept a m8 bolt : )
