Hi all, just a small factual post really, may be of some help to members who are wrestling with leaky a/c on their T2's!
I am fortunate enough to be able to do my own a/c work, and so was able to progress at my own pace not under labour cost constraints.
I've had a leak on the pipe that crosses the top of the Condensor at the front of the vehicle under the center rubber sleeve - a common problem as the sleeves suck up moisture, especially road salt which then rots the alloy pipe underneath. The new pipe comes without the center sleeve (hint hint..!)
Anyhow, I got my pipe from the local Ford dealer overnight (part no. 92440-7F410), for £45. It comes with new o-rings, but I ordered some anyhow, as we werent sure it would.
Nissan wanted £75 and there was a 2 week back order. Needless I told them where to go!
I have the parts diagram for anyone else who needs bits.
The battery & grille have to come out to get access to the ends of the pipe, and whilst it was out, I renewed the receiver-drier, and all the o-rings. The alloy fittings can corrode and strip threads when you try to undo them,so plenty of WD40 and praying is needed.
The grille is secured by two clips at the top, one in the middle and two at the bottom. The latter are released by using a flat blade s/driver and turning the square center about 45degrees.
I had suspected I had a small leak in the Condensor (oil patch on the core) so at this point I vac'd the system for an hour then let it sit overnight. Sadly the next morning we were down from 29in Mercury to about 24, so the condensor was indeed guilty. The bonnet catch mounting is bolted at the bottom to the cross member but spot welded at the top where it meets the slam panel! I drilled out the spot welds to 2 accept M8 bolts and was able to get the thing out of the way, catch still on it. The aux-fan (if fitted) needs to come off, and it is very tight for access- you are meant to remove the bumper officially, but with abit of jigglery it will come out.
The large fitting onto the condensor was very stubborn, and stripped the thread on the condensor side, but luckily the nut threads were ok (big relief!) I changed all the o-rings as a matter of course. Patience and plenty of WD40 helps.
This time the system vac'd down nice and held, so 750grams of R134a later we were away!
To finish off I coated all the fittings and pipes in waxoyl to keep out the salt and corrosion.
Just to note- if you replace the drier add 5ml PAG oil, if you change the condensor, add 75ml of oil.
I use Sevac http://www.aircongas.co.uk/ to supply the condensor (part 16-6202 £75) and drier (part 31-7007 £28) who are always very helpful. The condensor was a chinese made part, but the quality & fit seems pretty good, and it came precharged with nitrogen which is a good sign.
Hope this helps! Tim.
