F1 reservoir overflowing????

When you open the car door the fluid should go down as it primes the pump.
If it was filled with the door open it will inevitably be 'over filled' once everything is primed and the fluids level off.

 

Until you figured out exactly what's going on, I would if I were you. Also mop up the mess the best you can. Even though the pump is behind a side panel, you don't want any stray fluid landing on a hot cat and cause a fire.

 

That is normal when the F1 reserboir is overfilled. As she heats up, the fluid expands and is puked over the side. Except for being messy, will not cause any problems like overfilling the engine oil will.

 

Yap Taz is right this is overfill, do not follow the owner manual on F1 fluid. I know there a thread about this on how much to check and fill the F1 fluid

 

As said -- do not be a dipstick and use the dipstick. The correct level is 5mm above the screen in the bottom of the reservoir. Not sure if that is when the fluid is cold or warm -- someone chime in.

The dipstick is wrong:

Correct -- not sure you need the fancy pump -- a turkey baster with a plastic tube on the end would do. Still doesn't say check hot or cold though.

When pressure inside the F1 system drop, fluid are push back to the Reservoir. Once the F1 system run/in-use/pressurize, then the fluid should drop.
In my opinion that's overfilled, a bit too much(better then under filled, right?)....But yeah, clean up that mess, engine bay are hot and not a good combination any fluid leak that can ignite in flame.
Good luck...

 

I fill mine to the line around the center of the canister. This also corresponds with the tip of the dip stick approx. At that level, all is well. A factory tech told me to fill to the first line from the tip of the dip stick. No need to regret the F1, just fill to the level I described and you're good.

 

+1 on that. Don't regret the F1...It is an awsome!!!(little bit unreliable thoug) system design and works the way you would not able to do with a "stick", if you have it on the track. Ferrari are race cars design and that's what the F1 system is for. Driving around town and with alot of up/down grade/hill, it will be a nightmare. Ferrari cars does not like stop and go traffic, it likes constant moving fast speed. Bring it out to the track or open road, do triple digits, with setting on "sport". Shift that sucker and you will appreciate the F1 system...You have to experience it to know what I am talking about. The feel and the way it function, you can't do it with a "stick", unless you are a professional racer that eat, sleep, and **** out at the track most of the day in the year. LOL.
I didn't like the F1 system much when I first got it, but after getting to know the system and how it function, it's kinda cool...People still make fun of me when they check out my car, "why would you drive an automatic Ferrari" they say, I smile and walk away. I looked around and notice I was the only one driving a Ferrari with a crowd checking out the car...So how many of these people really know about Ferrari??? Too bad, I was the only one who gets to own one, drive one, and know one in that crowd...Hahahaha.

 

Oh, by the way...Does isn't Ferrari stop making stick after 04 or 05?
I thought all 430 and whatever after that are F1?

 

Mike- Nope, there were F430s, 612s, 599s, and even a few Californias with three pedals. Quite a few F430s, in fact, although I do not have any hard numbers.

There is a ledge in the F1 tank and that is the fill line the technical bulletin is designed to reach. On many F1 cars, Ferrari techs have broken off the old dipsticks because they are misleading. And no, overfilling slightly is not a good idea, as ccalo discovered. No harm caused, but ATF fluid, which is basically what F1 fluid is, makes a pretty good mess.

 

When checking the fluid level:
Hot vs. cold?
If cold, then system pressurized or depressurized?
If cold and depressurized, then how long for the system to depressurize after opening a door (overnight)?

 

The Temp has very little to do with "pressurize and or depressurize"...How well the system hold pressure, how long the system can hold pressure, and how long does the pump runs when the pressure is depleted....its all depend on how well the system hold/maintain the pressure. This is when the Accumulator unit and the Pump unit comes in play.
I didn't answere to clearly on the fluid level part in effect with temp...But hopefully that would answere "how long system pressurize/depressurize" vs temp.

Actually the opposite effect:

To summarize, the correct procedure is a cold car, open the door and turn on the key to prime the pump. When the pump has pressurized, then adjust the fluid level to 5 mm +/- 1 mm above the screen. Don't use the dipstick.

If you do this with the door closed, key off, and the pump not primed, then you will overfill.

 

Only on the F1 F355 is it necessary to use the key to pressurize the system with the F1 pump. On the rest, just opening the door will do it. The pump shuts off as soon as the system is happy with pressure.

 

Uhmm... If you open the door, as you said the pump pressurises. However, if you then turn the key immediately after the pump will pressurise some more (at least in mine it does!) which makes me think that the door-opening triggers a priming but not a full pressurising maybe?

 

Beats me. Whenever the pump actuates, by whatever means, she pumps up to operating pressure and does not cycle again until pressure drops below a threshhold around 800 psi. I would not expect the pump to cycle again when the igntion turns on unless there had been a considerable delay between opening the door and starting the engine.
