Now then folks.
Im contemplating removing my AC from my 968, Less weight + more speed...[:D][:D]. The AC compressor + rad etc weight a fair bit...
BUT.
Do i have to remove the AC gas before i undo the AC rad or assosiated pipework..???

As + when i do this, the AC system will be for sale, and i am removing it sympathetically + hoping not to damage any of the fittings...Anyone interested.??? It works perfectly....
 
You should get the gas professionally removed and disposed of. Unless you're taking out the dash to remove the evapourator it won;t be complete, you'll struggle to get the lines out with the engine in place (it might very well not be possible), the condenser will probably look half dead and the receiver/drier is disposable if it's left open to atmosphere for any time.

Basically the compressor will come out and has a resale value, but the rest of it will either stay in or be junk in my experience. I got the lines out of mine only because the engine was out and my evapourator is still in the car.

It would probably fit a 1986 Lux, but it would be an engine and dash out job to fit it and it's possible the 968 system is slightly different to the 944 one.
 
the previous owner of my S2 removed the airconn and since I bought it the heater never works properly. The cabin fills up with condensation as soon as the outside temp drops ,all the glass is misted constantly and I'm constantly driving with the heater full on and the roof and one window open. [:mad:][:mad:][:mad:] what was the idiot thinking of . well I know i think he was intending to use it for trackdays.

You'll need a replacement alternator bracket & belts too
 
Ok chaps.
The system thats in the car is a retro fit system, in that when it was bought new[the car] it came without AC, but the first owner had the AC fitted [At the OPC where he bought the car from],about a week after buying the care,, Go figure.!!!!!. So its a Porsche AC system but there is more flexi pipework than the "factory fit" stuff. Ive checked this back to back [side buy side],,with a "factory fit" car. + The Factory fit has more hard / metal pipework than mine..
So im hoping itl come out easier.
Yes i realise ill need a different alternator braket + belt, + have one ready for the swap.
I was contemplating leaving the dash mounted "evaporator" in place, but i think itl have to be changed for a normal heater element type...
A good m8 of mine has recently had to replace his heater element + is now a dab hand at remving the dash.. He also tells me that he can remove the element with the dash still in place...He has done it... Hopefully making it a "slightly "easier job...!!!!!....
The system thats in now has been serviced ,Ive got a thick file of reciepts amounting to £££££ for the work,,,.. Oh + it has the correct NEW type gas in it.. It works great, its just heavy....+ it also blocks the flow of cold air to the water radiator making the car run warmer than it should, not good for a track car....
 
You're ahead of me on the evaporator and if the pipes went in with the engine in situ then they will come out OK.

I believe the evaporator sits in the intake air flow in the scuttle and chills the cold air that the rest of the heater system blends with warm air coming through the heater matrix. Aside the cold air intake having a chiller in it the rest is identical as far as I am aware. The evaporator is half inside the car though and I was advised the dash needs to come out to release it.

The above being the case (and I've seen the evaporator in my car and that there isn't anything there in my non-air con S2 cab, so I'm pretty happy I'm right) I can't see how the demisting would be compromised, and it certainly isn't im my car. I'd suggest you might have a water leak into the cold air intake in the scuttle, Nick. Take the plastic cover off and lift the lid on the blower bow to check the seals.
 
Nick. Its funny you should mention, that the car mists up quickly. + demists slowly with the AC installed but not switched on...
I have 3 cars,[ in the family] all with AC, + they all do exactly the same thing. The only way to demist the car successfuly is to turn the AC on....Must be something to do with air flow or something....?????

I haven't really looked too closely at what he did in removing the A/C but judging by the fact he used gaffa tape to repair the cassette hinge and the carpet around the rear hatch switch I don't think he is likely to have done a very good job.
I think you are probably right about blocked drains in the scuttle. The car is parked under firs all year and I have to remove a shedload of leaves and needles.(fir tree) [:D]
If its nice tomorrow I'll clean the lot out thoroughly. No water inside the car as far as I can make out though. I've always assumed it is a recirculatory problem due to a bodge
