My air con in my GQ has been farked for the last 2 years or so and i have neaver had air con in the air con since i owned it but that's becuase it need regasing and a couple of wires back in the compressor that were pulled out.

Is there any air con experts here and can tell me what the ussally go is when re gasing air con and stuff is there usally a few other things that need to be done etc?

The reason i'm thinking of taking it out is becuase i don't use it but that's becuase it doesn't work and i'm thinking about taking the whole thing out all that radaitior thingo and fan and all the pipes and stuff and then i can fit my new intercooler much easyier and get rid of all that ugly pipe and junk.

Then running a intercooler out front then air con rad and then the engine rad arn't i going to have a few cooling issues??

I'll make a poll and get everones oppion as i don't if i should take it out and neaver have air con again or leave it there and try work around all the pipes and remove that fan etc..


Thanks alot for ya help

Air con adds value to a vehicle.

As for fixing it it ready depends why it has no gas as to what is required for repair.

If you have removed it and just dumped the gas to atmosphere (big NO NO) and pluged the pipes it would need to be put on vac/pressure tested and then regassed probly change the dryer and oil at the same time.

if you have brocken a pipe or have old lines that are leaking or leaking seals its a different story.

When i checked how much gas it had in it becuase i needed to remove a hose i cracked a hose and it psht for about 2 seconds then stoped and that's all that was in it.

So i have had a hose removed off the air con for last 4 months or so..

One hose that will need fixing as it has pershed and brittle and not sure what else needes to be done would u be able to give a rough price to fix everything up to weigh up the idea is it worth it or not..

Did you plug the pipes?

The gas in your AC is a chlouro-fluro-carbon (R12) (CFC = ozone depleting). You can't get it anymore without a special permit. The gas they use now is a hydro-chlouro-fluro-carbon (HCFC = ozone freindly). This means a retro-fit of your system. It will mean new oil, seals etc to accept the new gas. I had a 92 Mav SWB and i think the quote was around 600 big ones. I never got around to changing it over prior to upgrading. If you don't use it and don't want it anymore, spend the money to convert it to an endless air.

WOW $600 i'm not spending that for air con rather go hot and go fast :naughty: :naughty:


Is there anyone on here that services car air con and just give me roughl figure to get everything sorted like new hose from fire wall to front of car and whatever else like new seals etc..

I do Air-conditioning commercialy but do cars and refigeration on the side.

You havnt pluged the lines which means the compressor will need to be striped and cleaned and the lines flushed with the tx removed it'd be cheeper to fit an AC compressor from a later model from a wreaker.

If you have more need for endless air the it would be perfect for conversion.

you would be looking at $600 minimum depending how dirty it all is to re-instate the air conditioning.

you could refirb the compressor for an air set up for far less around $200 for everthing you need ie filter tank pressure switch oiler etc.

for those interesed CFC's like R12 are no longer available however treere are now drop in replacments that are compatable with the old oils and can be use with old systems.

HCFC's like R134 are not ozone freindly they are just less harmfull.

If you know where to go you can still get R12 it will just cost you alot.

Cheers

My 88 (black over grey) gets pretty damn warm in summer and thats Sydney - your 1000 k's+ north so even hotter!

When I brought it in from Japan about 3 years ago the A/C had no gas in it - probably haddn't worked for at least a year or 2. Once I got it regassed it worked really well at first but then after a couple of months started getting weaker, I also noticed a strange hissing sound coming out of the vents so I pretty much knew where the leak was. Pulled out the fan blower and removed the evoporator coil and tx valve from under the dash ordered in new parts from an AC supplier (non genuine) all up about $400 for coil, tx valve, seals, and dryer put it all back together got it regassed and away it went - really well untill I heard a pitched squealling - I haddn't tightened up one of the joins properly and had to pull out the fan again to get the spanners in there!

I'll top it back up before next summer so its full again and hopefully it should be fine (still works but due to the initial gas loss not optimal).

So i'd start by getting it gassed and see if it holds its pressure and go from there (once you replace your hoses - these could have been the problem), otherwise if your lucky it might just be a seal somewhere in the engine bay area there ony 5 bucks each or so. Probaby best to do these and the dryer anyway then get it gassed - just make sure to tighten everything up!

Oh yeah there was heaps of composted leaves and mouldy crap in the AC coil box too, took a bit of cleaning! Probably not the best stuff to be inhaling!

cheers,

Dave
