I am seroius about an all new A/C system for my 308...
 
any suggestions? Is there an aftermarket upgrade worthwhile? My car has service records showing the previous owner spent much on refurbishing the factory system, which is still WAY too weak, it's so hot in my black berlinetta that I can hardly stand it!! I'm willing to replace everything with something that actually cools the cabin, but WHAT???? I know some of you great people here can give me good advice, so let's hear it!! Ciao! Dennis

I think it would be easier to change your interior to white :) . OK, OK, according to the parts book, European cars use what looks like a Sanden compressor, which is much more efficient than the prehistoric USA York compressor. Maybe our European friends can comment. Of course, all the mounting brackets would have to be changed, but at least those parts exist. It's a pretty tight squeeze in there between the engine and the gas tank. -Steve

Okay, looking over the receipts from the previous owner I see that the A/C has been converted to the r134a refridgerant, but it does not blow cold, so if I have it checked for leaks, repair the leaks and recharge the refridgerant, will it be cold? From what I hear, they just never were any good, even new! Is this true? Today was 30C in full sun, and I have a black berlinetta!!! I was baking in there, still loved cruisin' though, heehee. Man I really want it to be comfortably cool inside, I don't want a sound system, just air conditioning!!! So does anyone have a 308 with great air conditioning? Should I have the system checked and recharged, or is that more or less a waste of time and money when the result will still be the perverbial mouse blowing through a straw???? Please help me keep my cool!! Dennis

The AC in my Euro 1975 308 GTB now works very well. Had it serviced earlier this year and the gas recharged. Works much better than the system in had in the old 512 BB.

Key was getting the gas recharged.

You live in Canada man! How can it be too hot?? :) The A/C in my 308 doesn't work, didn't work when I bought it and I never bothered fixing it. Of course I have a GTS so I just take the roof off. That helps. :)

The R134 is not as good of a refridgerant as the old R12. It will seep through the hoses. Go ahead and get the system completely evacuated, checked for leaks and recharged. When they recharge it, have them put in some AC system sealer. Give that a try before we go ripping everything out.

I usually have to throw one can or R134 in my truck every year. I've had it in the shop and no one has been able to find the leak. I've already spent a few hundred bucks and they've told me what they think it is. I've finally stopped spending money trying to figure out where the refridgerant is going and every year I just add another can when it stops blowing cold.

I remember the AC in my old '77 Mercury Grand Marquis. That was an R12 system and on the hottest day of the year you could put it on high and blow snow out the vents!

I was just about to post a reply, but Capt. Pete beat me to it. (Pete, why are you up at 2am?). Anyway, I was going to say the same thing. Get it recharged and see if that makes you happy. It's a cheap try. -Steve

I was varnishing the cabinets for my wife's home office. I had fallen asleep on the couch and woke up around 11:00, worked on the office stuff for 3 hours then checked the forum before heading to bed.

That is one of the great things about my 3 week on - 3 week off schedule. When I am home for 3 weeks I really don't need a clock. I sleep when I am tired, I eat when I am hungry and I work when I feel like it. :) I woke back up and got out of bed around 9:30 this morning. Went outside and built a stone firepit (60 pink granite blocks with a red clay brick base, it came out pretty nice).

Ferrari328GT 05-10-2007 11:57 AM

Good excuse, Pete. Since it is now 100 degrees here in the afternoon, I, too, get up early and do what I can outside before it gets too toasty. Yesterday, I was inspecting some cactus I planted, and noticed something about two feet from my right foot - a three foot long snake. It took maybe three seconds of heart-pounding time before it registered in my brain that it was not a rattlesnake, just a beneficial king snake. Does wake you up in a hurry, though. -Steve

Pete, It sounds like the same schedule you had your 1st year on this planet. :D

Yes, I enjoyed it then and I enjoy it now. :) Of course now I still have to clean myself. Maybe in another 40 years I'll have someone to do that for me. :)

Well, they say we are born in diapers and die in diapers. So make the most of the period in between.

and that is why I have a Ferrari.

Me too. :)

Agree with all of the above - re-charge (& dye) see how you go.

I was working on the a/c of a vehicle of far-eastern origin today (make to embarrasing to admit to :o ) and found 3 leaks - interestingly they were all dodgy seals. But what was annoying was that this vehicle had obviously been in to some place before for the same thing and there was weak dye all over the place - I spent ages cleaning the [email protected] off the pipes before I could actually see my dye coming through. I hate messy work!

GeoMetry 09-30-2007 04:16 PM

OK this is my first post here. I searched before posting and I found this thread which is pretty much the exact question I have. I had a 308 and I will soon have one again. The A/C never really could keep the car cool (especially in traffic) so I am willing to compromise the originality of the car in order to get nice cold A/C so that I can drive it and enjoy it more. So isn't there a nice universal after market system that I could have installed that would actually work?

Ferrari328GT 10-01-2007 10:06 PM

Well, GeoMetry, I'm afraid you'll have to make up your own replacement system. First, I suggest a Sanden compressor, as I mentioned in a previous reply. Then, remove the condenser and see if you can find a "serpentine" substitute with the same dimensions. The stock one is a "tube and fin" design. Newer "serpentine" style condensers are much more efficient - they have flat, wide tubes instead of round ones, and offer more surface area with less air flow restriction. I have never taken an evaporator out of a Ferrari, but I assume it is a major job, so I'd probably leave it alone, and see if the other two changes make the system acceptable. Good luck. -Steve

I have a black berlinetta as well and the AC worked very well this summer, it had been recharged by a specialist in june, and he put an additive to see if there's no leak... Of course it's not a lexus one but very fresh either on highway or city traffic jam. I have a euro version and I didn't change the compressor which is an autobhan (?), there's at least one piece I didn't change on my car...

Boxer 10-02-2007 10:50 AM

Mine is still working quite well 8 months after it was recharged. It kept the car reasonable in 40C heat a few weeks ago.

Dino246gt 10-02-2007 08:10 PM

Thanks everyone, I had my system checked and it is recommended that a fresh charge will make it work well, so I'll do that next Spring............BUT...........I did add the power window accelerators, so I rode around all summer with open windows, something that I couldn't do when I first got the car. Well, the windows sort of worked, but needed manual assist! Opening windows, old school air conditioning, ha ha!!
