430 Need Your Help - Coolant System Just Blew Up!

Hello All - I am seeking your expertise & guidance regarding diagnosing a coolant system leak that happened today with my 07 F430.
Let me preface by saying that the car has run flawless with Zero leaks of any kind. I pretty consistently drive the car once, maybe twice a week going to the gym or over to a friends house, totally about 20 miles per week. I always inspect engine bay to look for leaks any kind after each drive and I don't hot-rod the car or push it to the red-line. I never shift beyond 7500rpm - admittedly, I "granny" drive most of the time. In addition, I put it up on the rack 2x per year to look for any fluid leaks.

With that said, on the way back from the gym this morning, I pull away from the light, at about 3/4 throttle I shift from 2nd into 3rd at 6krpm, a second or two later, I hear a "whistle" like pitch, almost like a sucking noise-type pitch, looking to the rear-view mirror and I see a light stream (not just a steam/spray) but a consistent stream of coolant shoot up from the engine bay and hitting the deck-hatch glass. I'm like WTF!??? First thought is a hose from the coolant tank came loose. Pull over, pop the hatch, I see steam/coolant spraying up from somewhere under the three reservoirs tanks. Nurse the car home. Note - no warning or check engine light came on!.Let it cool. From up on top, all hoses are connected. I can't get down into the engine bay enough to check to see if any hose connected to the engine have come loose. Given the way this just all of a suddenly happened, I am guessing a hose and/or clamp has come loose. I am praying not a head gasket issue.

Seeking everyone's input for possible diagnosis. I did go out to Ricambi to look at the coolant system diagrams, however, their web-site has changed and I can't find a diagram that shows where the coolant hose(s) connect to the engine. Most likely will have to flat-bed the car into my dealer for fix.
Your input is most appreciated

All - I want to thank everyone for your replies and how to go about finding the leak. The diagram posted was exactly what I was searching for on the Ricambi site. Agreed, based on where I saw the spray/leak coming from, #18 hose leading to the manifold may very well be the culprit. And good advise, I might as well change out old hoses for new.
Very much appreciated to all!

 

All - posting this info as an FYI to help others where applicable regarding repair cost. I decided to take the 430 to my Indy repair shop. As expected is was the primary coolant hose going into the manifold. All told, cost $2900 to fix (parts (fluids/gaskets/clamps) & labor). Parts were only $660, remaining cost was labor. Indy repair shop explained that the labor was 11-12hrs as they had to pull the manifold to replace the hose. Labor seems a little excessive...but OK, not gonna lose sleep over it. Care runs like a champ and glad to have my "Prancing Pony" back in the garage. Of course, my wife is not happy that she has to park in the driveway again as both my F430 and Shelby GT500 have garage priority.
As mentioned above by "ditpixs", YES!, this was the most expensive hose replacement I've ever experienced.
