    My heat exchanger died on my 360 6 speed Spider and filled the gearbox with coolant. It’s been suggested to me that perhaps I should delete the cooler altogether. Other suggestion is to replace it with an air to oil cooler like on an automatic transmission. I’m concerned that might over cool the oil which I fear will make the shift notchey and tight. I’m chasing thoughts on this asap.

    This style of heat exchanger also serves as a warmer for the gearbox fluid, cleanup is a PIA, but why change from stock? It works.

    Thank you very much. I’m going to delete it. Relative to the use it will receive, I’m confident it’s not a huge loss.

    I have had requests to delete them, and have done so. I install new lines modified to work with an external cooler which I mount in the opening behined the rear wheel. The wheel well cover needs to be cut open to allow the air flow and a screen installed. Mounting brackets need to be made up for the cooler, the lines modified to fit the cooler..etc.

    That said..its cheaper to replace the stock unit.

    Just changed mine, as PM sinceI had the intake off. Original lasted for 55k, with proper maintenance, my new one should last past 100k. under $500 to replace. No need to get cute.

    I’m told on a Spider that the entire roof assembly has to come off in order to replace it.

    You have been told a lie. Intake does not need to be removed either..

    That’s very interesting. I’m told beyond any doubt that the roof AND the intake has to come off. Im not doubting you, but can others please chime in to confirm this?

    Here’s a pic from my spider moments before I pulled the exchanger. Just go through the belt access cover and pull the water pump first.

    Roof does not have to come off. I have seen a heat exchanger replacement and a bypass done without removing the water pump or the intake!!

    How is the bypass done? What components are used? Just curious.

    Mine was replaced with the upgraded one from Daytona (made with a different material) and the roof did not have to be taken off.
    Now that I am personally taking care of the cooling system (changing the fluid every 2 years) I will no longer worry about this item failing (fingers crossed)

    However, at any hint of degradation of this HX I will eliminate it.

    The only materials used was a good quality coolant hose. He just took his time and got the clamps off, slid the heat exchanger out and replaced it with the hose and new clamps. It was magic to watch!!!

    Can folks who have deleted the cooler altogether share their post-install feedback?

    I am thinking (1) this is a heater more than a cooler as the gear oil takes longer to warm up than does the water and perhaps Ferrari was addressing its notorious difficulty of shifting into second gear until the gearbox was warmed up?

    (2) is this really a cooler that is needed? Does the gearbox in the F355 really run that hot that it needs an external cooler?

    For those who have bypassed, any cold shifting issues? Any overheating gearbox issues?

    Without personal experience (which I will soon have, as I've got a leak too) I'm guessing that "it depends" and Ferrari has done it for a reason, to address various conditions.

    So for someone racing and overheating gearbox, or driving in a polar bear country and needing gearbox warmed up - a new heat exchanger is needed.

    With reasonable street driving in a climate like Florida I think we can live without it. Unless originality is important.

    You can live without it. Do the loop bypass and you will be just fine. As stated it is not really a cooler..it's more of a heater then anything. If you are really concerned, you could add a remote cooler rather easily.

    Mine failed and I replaced it with an OEM unit. It was an absolute PIA. However, Ferrari did the R&D and put one in for a reason. The Challenge cars have a cooler that is external to the V, which is nice.
