    To reduce the operating temperature of my Ferrari 360 Spider F1 hydraulic pump I have installed an aluminum radiator. The attached pictures demonstrate the pump with and without the radiator.

    I made this radiator myself from a tubular radiator that I cut with a band-saw into 3 sections 60* each. Two sections (120*) of this tubular radiator applied over the electrical motor of this pump fit perfectly and don't interfere with the frame to which the F1 hydraulic pump is bolted on. It took me 1 minute to install this radiator using a stainless steel hose clamp, and I did not even have to unscrew or detach the F1 pump from it's frame!

    Using an infrared digital thermometer, I have determined a significant drop (34%) in operating temperature of the pump. Namely, I measured temperature before starting the engine in the morning and after driving about 20 miles first day without and the next day with the radiator installed.

    I dont know yet how this will affect the "longevity" of this pump, but theoretically reducing the operating temperature should extend it.

    Your comments are welcome.

    Only one word. Awesome!

    It is always great to see that owners discover Ferrari's short coming in many aspects of their car design and make improvement and coming up with fixes for what Ferrari should have done in the first place!

    Juri,

    That looks pretty neat. Where did you get the "raidiator" or heatsink from?

    It would also be interesting to know how hot the F1 fluid actually gets. It is right by the muffler and there is a little heatshield on the metal panel by the muffler. I don't think there is any raidiator to cool the fluid either.

    I'm wondering if the fluid gets too hot if that would cause problelms as well.

    Jim,

    The radiator heat sink is used in aerospace industry and in custom tubro applications as a pre-intercooler pipe. The inner diameter is 2.5" which matches the outer diameter of electric motor of the F1 pump. To further improve the cooling effect, I am planning to add an electric ventilator at the end of the radiator, which will blow air from the end of the radiator over the fins towards the pump head.

    Forgot to mention, that I had covered the inside surface of each radiator with a thermocoupling paste to improve the thermal conductivity.

    You are right about the fluid heating up. To reduce heating from engine and, especially from the muffler, Ferrari engineers used a woven fiberglass sleeve to insulate a bunch of hydraulic lines going from hydraulic power unit to the gear actuator. Hot hydraulic fluid certainly adds to the heat of the F1 pump, which propagates from the pump head to the electric motor. Consequently, the ferromagnetic stators inside the electric motor expand and start brushing against the rotor, which generates a lot of "shavings" that cause shortage of the electric motor contacts inside. I had described this before:

    Juri, I have a f430 and want to know where I can purchase the radiator for the Hydraulic F1 Pump you created. I am having a common problem with my car not going into reverse after having driven the car for about 30 minutes or so. After the car cools for about 10 minutes or so it goes into reverse just fine. Please advise.....and thank you very much!

    IIRC Ricambi used to sell one of these but Daniel said they discontinued them as they proved not to be effective.

    Your issue may be related to something other than temperature of the fluid otherwise every other 430 would have the same issue. Perhaps a sensor that when heated loses a good connection?

    I have been told this F1 pump is exactly the same as the one Alfa Romeo uses on their Selespeed gearboxes.
    The main difference is price tag...3 times more if you buy from Ferrari dealer instead from Alfa Romeo.

    The heat sink wont help with your issue. I suspect the clutch is dragging on the flywheel when it heats up - the TCU wont engage reverse if the input shaft is moving. You'll need a shop with the proper diagnostic equipment to resolve this.

    Thanks for the reply guys. I have had the car diagnosed and Ferrari cannot find anything out of sorts. It only seems to happen when the car is driven a while once it reaches operating temp. Based on some of the posts regarding this issue I assumed it was the F1 Hydraulic pump heating up. I will have it replaced to see if that corrects the issue. Thanks for the posts. I really appreciate it.

    I have a occasionally the same issue, Ferrari have told me exactly the same. All OK and nothing wrong!
    Can be very frustrating and embarrassing at times.
    I would greatly appreciate your feed back on how you rectify the problem if you wouldn't mind PMing me. If I beat you too it then naturally ill let you know.

    All the best and good luck.

    Seriously. I believe Voicey's comment is on the money.

    As a temporary work around, you may be about to get where you want to go by first selecting 1st and then select R.

    If it was being caused by the pump it would have insufficient pressure and if you had insufficient pressure you would have a warning light. In any event your problem is not a symptom of low pressure.

    If buying needless parts gives you a thrill knock yourself out.

    I m finally and gradually getting the f1 system monitoring install. I will share that in a bit. But start off, on this thread, yes that is a nice add on heat sink to disepate the heat from the pump. But the bigger question is why is the pump running hotter then normal???
    I have heard alot and common is "I can't duplicate the issue, or there is nothing wrong"...Well, as we all know and need to take a few small aspect which we tend to over look and put it in a bigger picture: 1 as time goes by, pump worn out, intern this will cause high resistance in the pump and will produce heat. 2 Heat inside the engine compartment penetrate the pump will cause pump to heat up. 3 pump runs more then normal, do to failure of relay or air in the system will also cause pump to heat up. So far we have 3 most common cause make the pump to run hotter then normal.
    So, as you can see and self explain "why do we have gear shifting issue when car gets hot?" I am sure there are lots more reason and area, but so far the leading point is still remain that your pressure is depleting and the pump is not able to keep it up...
    Please feel free to common and add to my thought..

    Engine comp is always hot, That is a constant between cars. If there is air in the system it will malfunction just like your brakes and unless the car was subject of poor, improper service procedures it is pretty unlikely. It would have to be a severe case of air to cause a pump problem and again warning light time. It almost never happens so I really discount both. Again any time the pump is not doing its job and preventing proper operation you will be getting a warning light for insufficient pressure. If that is not happening you don't have a pump problem.

    A bad relay is why pumps overheat and die. Sometimes old age.

    Brian- Most people seem to think the F1 pump runs all the time. As you know, it does not and should have time to cool between cycles, except it lives in a very hot environment. If it does run continuously, usually from a bad 30 amp pump relay, it burns out.

    Yes, Brian. I totally agree with you as a stand point if the system is obvious complete fail or no fail that can easily identify. In some cases, it would be intermitten and or just barely begin to fail. Cutting in and out, more so on the NOT failing side then failing side. Or not entirely failed. That is why when technician trouble shoot, it can be easily overlook because of "flat rate" shop. (sorry, not trying to point finger and anyone). Most of the time, I notice, we tend to overlook things that are just right under our nose.
    Base on theory of operation, we all may think that "how could air get into the system, when there was no air before? my car was running find for the last 40-60k miles and all of the certain air got in? make no sense!" Well, at our factory we have found diaphram from the accumulator goes bad, nitrogen gas then seep thru and get into the fluid. Nitrogen suppose to absorb in the fluid, but guess what? one of the clue for that is your fluid level certainly raise....You may ask yourself, why is my fluid overflow when I never add any fluid in it?
    I some time work with product engineer and have seen some bizzard cause effect that its hard to explain, and even when you try to make sense of it. It sounds crazy...lol
    In anycase, I that I should share that. Give me sometime to finalize my "bell and whistle" from the f1 system. I thought its pretty cool...
    I will post new thread "f1 system monitoring"
    talk to you guys soon.

    Yes, worked for me when this happened to me. Have pis setting checked if it continues.
    Mine stopped doing it after a few weeks. So far so good.
    Shop that worked on my car drove my car, when I got it home it would not go into
    reverse, never had that problem before.

    That's because they set the PIS too low and the clutch was dragging.
