Heat exchangers

The same cooler is used in both cars. On the F355, it is directly behind the waterpump. See #12 here:

12 is a water/oil exchanger. FerrariDublin did a nice write up a few years ago where he cut one apart to show the cross section. It looks like a coffee can packed with drinking straws.

Both 355 and 360 use the same heat exchanger.the transmission has an oil pump for the oil.

 

I had a 355 with 5k miles the exchanger gave out. Drive your cars and more you dive, the less issues you will have.
I replaced my own. Coolant runs on the inner tiny ports and cools the trans oil that ciculates around the water ports and returns to the trans via the second braided line. If it goes out, water finds its way into the trans since the pressure is higher that the gear oil. Some gear oil also will find its way into the cooling system. Belive me, you will know by the sell in the car while turning the heater on. Does not always mix into the cooling system though. To clean it up, take the whole top of the engine apart between the intake plenums, remove the throthle linkage cable and the heat exchanger. Find a water heater source to hook up to your intake coolant hose and turn the garden or the hoe water heater valve on, open both radiator drain plugs, turn on the heater, connect another garden hose to the return line of the cooling system and start the vehicle for about 30 minutes. When the coolant system is free of oil, put the car back together and hope the new exchanger goes a long way.

IF need to discuss in further detail, feel free to leave a PM and I will gladly call you

Oh boy. Here we go again. Next thing you know it will be, "they all fail; it's just a matter of time." You have the love the BS on this site.

I don't think anyone implies that it all fails. If it fails, the process was described as pretty straight forward. I think that is good. My 355 heat exchanger has not failed, but the banjo bolt ($35 piece of aluminum) did crack and was replaced.

 

Hey Bob. Not aimed at you. It's just that the 355 forum seems to be a dumping ground for any problem anybody has on their car and before you know it, it becomes the next black mark against the 355. Doesn't matter if its a unique problem or one documented to occur on most Ferraris. You know, if you look at the original cost of one of these cars back in 95, around $140k out the door, in today's dollars that's over $300k. So instead of constantly complaining about this or that problem or cheaping out and performing a DIY major because a shop will charge $5-$8k, be thankful you can get your hands on one of these beautiful machines for effectively little more than a loaded Ford Expedition! The place just reminds me of Rosanne Rosannadana, "While answering the questions, she would invariably digress, launching into a lengthy anecdote with no relevance to the topic at hand. Invariably, the story would lead into Roseannadanna's going into disgustingly graphic detail about bodily functions or personal hygiene; with these details, she would use a famous celebrity as an example and say that she would ask these celebrities, "What are ya tryin' to do, make me sick?!"

Eventually, Jane Curtin would interrupt. Curtin would then ask her what her comments had to do with the question. Roseannadanna's response was, "Well, Jane, it just goes to show you, it's always something--if it ain't one thing, it's another." Either the headers on your F355 are cracked or the valve guides are shot, and so on and so on.

Sorry you set me off, but my opinion of this site, from a technical stand point, is pretty low. Seems more like a support group for recovering want to be Ferrariholics. I kind of feel that if you could not have afforded one of these cars new you shouldn't own one now. Maintenance cost don't go down with time. If you think $7k for a major is outrageous now, wait 5 years.

End rant.

 

Somebody needs to take one of their clips and dub in these words and post it on YouTube! I'm laughing just thinking about it.

 

Not mine to allow. They pay me for it. it's theirs.

At least I think they paid me, I don't know I never keep track, I just deposit the checks whenever they show up.

 

Oy Vay have not herd that word since I been in Calafornee

 

I just love these threads compalining about another typical 355 issue. Hey dudes, they are highly strung performance cars, not Hondas. You are going to have things come up from time to time. Interestingly, the more you drive your car, the less likely some of these are to occur. Hmm. So you can be your own preventitive maintainer by simply driving those things! Works for me.

 

Its more of an issue with the 360 because the heat exchanger is not built the same for the 360 as it was for the 355. The early 360s I believe have the same exchanger as the 355 but later years it was built by a different company. The later ones (most 360s) don't have the reinforcement built onto each side where the connection is made. This causes them to crack with the engine vibrations and you can have major engine damage if it goes undetected long enough. The other problem is that they are no longer made and a used one will only cause you more problems down the road. These are going on more cars than you think. Fortunately for us Daytona auto up here in Toronto has had some manufactured strictly for them and they are heavy duty compared to the OEM one. They are capable of handling 400psi compared to the OEMs 300psi. If you call Daytona for one, just ask for Alex and he will ship one to you. BTW they are made of copper and not brass like the OEM. When my next major comes up, I will be updating mine as a precaution.
