Loosing coolant on my 612

Anyone experienced this? After parking the car I find some coolant under the engine on the floor. I have checked the circle when cold with one bar pressure, bur no leak. Also when driving all is well. Only when the engine gets cold it looses some fluid. Any ideas?

 

44000km.

If it was the waterpump, it would fail also whilst driving I asume, isnt it?

 

The leakage seems to be more in the back of the engine from seeing where it drops when the car is at a standstill. I assume its not leaking when driving, because when the engine is warm the car does not loose any coolant, only when its cooling down (from warm to cold).

 

Thanks for the advice, the car drops indeed in the back, close to the clutch housing.

I also think its one of the hoses, a loose clamp or a sealing. B.t.w., Ferrari did pressure test the system with a cold engine but didnt didnt find any leakage. They said it might be some of the sealings which is where the coolant gets into the engine. Since it takes a hell of a lot time to remove everything to find out, incl. removing the air intake manifolds they recommend to wait until the next belt change and check then. In the meantime I should frequently check the level of the coolant. Anyway, its anoying to have a sort of incontinent car.

 

Finally a hose had burst, coolant all over the place. Mechanics are removing the manifold to see which one is damaged but will most probably replace all of them.
Costly repiar due to a lot of labor.

 

Thanks Jason, lets hope I have piece for next decade.
