I just took possession of a c63s and am wondering about the level of the turbo coolant.
This seems low to me, I added (about 100ml to reach the level of the jar), as soon as the engine is running, what I have just added "disappears" and it is again "empty"
I know he has a second jar (which I don't see) which must be full, I imagine because there is no warning on the dashboard.
Search 'coolant reservoir.' There's a lot of information to your question. It should maintain a level of coolant at half full. It's the secondary reservoir that helps cool the transmission oil cooler.
and yea, that is NOT turbo coolant.. do not fill with engine running, its a closed system, so let the car sit, unscrew the cap alittle to let air out, and let it settle, then fill it up.
If it keeps going down or empty, then you possiblty have a leak in the system.
Do you mean the both reservoirs can communicate together ? or is it 2 differents circuit ?
Front corner passenger side is the main, make sure that is full , other wise it will take for ever to keep trying to fill it via the secondary
if its full and you still get secondary coming up empty, then either a clog, and or leak
Ok i undesrtood now, the coolant i put into the "small" go into the large reservoir while rnning, that why level is low...could some one show me what is the correct level of the main reservoir, it not clear in the doc. 1,5cm over, but over what ?

well the First question is, is the main empty ? There are multiple things that go on with the coolant system, and your not being vary clear if you are having an issue, overheating, getting a coolant level indicator etc etc..
In general you dont want to overfill, since this system is under pressure.. so as long as its above the SENSOR in the reservoir you are fine.. you could stick a tape measure in, and measure it to be perfect, but I am not sticking a tape measure in my car..
that something i cant explain...trying to put the correct level of both reservoir...but impossible
It seems that all the fluide goes in the large one (passanger side) and the small become empty when a start engine.
(i havent drive) only in my garage. Should the 2 reservoirs will egalized level when driving ?
It's because the top reservoir that's visible is actually an overflow reservoir. If you're empty or below min, you need to fill. You may want to check for leaks.
And to be clear, this is coolant for the intercoolers and the transmission. Not engine coolant.
If you look inside the main large coolant reservoir there is a plastic piece running top to bottom. It changes from white to black where two plastics are joined. At this junction is where you maintain the coolant level. My SA told me the two reservoirs are for independent systems with two separate pumps, but they are somewhat linked in a manner that the small reservoir will serve as a runoff should the main reservoir be overfilled.

Alex is correct. They are 2 completely isolated systems. The LH side wheel radiator (in direction of car travel) and the front center large radiator are cooling the intercoolers and the transmission (although the transmission heat exchanger is a POS).. It is highly possible you have a slow leak from a stone strike on these radiators. Have you noticed any leaks? Go for a good drive, then come home and park up on some concrete. When the system is hot and pressurized it will force coolant through any holes.

sorry to intrude, but I had the same similar problem and realized that it was the “ Heat Exchanger” leaking. Now, another thing that I’ve notice is that once’s my car is up on temperature, the fan kicks on and it’s loud!!! The fan turns off when I turn the car off and let it cool down. Is it normal??
