So I have just had my first service since buying my MY12 Series 2 Calais sportswagon, the car came with books and had been going to Holden for it's for the first 100k of it's life, it had it's 105k service done by Holden at 99k it now has 110k so have decided to go in for an oil change and tune up and a once over, everything is fine with the car but I've been told my AC compressor is leaking oil and will eventually seize if I don't do anything about it, there is no noticeable change in AC performance or any strange noises so I was quite surprised. Has anyone had a similar issue and how did you go about fixing it? Is it worth replacing the seals or should I think about replacing the whole compressor, car is less than 3 years old.
A bit of research tells me compressors are around the $700 mark for most cars so I'm keeping my fingers crossed I don't need to replace the whole thing, I've noticed a couple of threads from VT/VX owners that have replaced gaskets themselves and just had the thing re gassed, not sure how easy it would be to do on a VE, I don't even know where the compressor is.
Hi. Definatly don't do this yourself its illegal as the escaping a/c gas will be dangerous for you if breathed in and very bad for the ozone. It will need to be evacuated from the system correctly. The oring seals will then be replaced and an a/c qualified person will regas the system to the correct pressure. A failing a/c system will still work and could work for another year or two before you notice any real signs ie not cooling well however by this stage you would have stuffed the compressor and will likely be up for $1100 + to fix whereas if you do it now will prolly cost less than $250. Its common for the seals to crack/perish and leak although 2 years is a bit of a joke. Best thing to do would be locate the a/c compressor google it and then look at the pipes that enter into the compressor generally if they have been leaking you will see the steel stained with a dry oil mark near the gasket. Check for this and maybe post a photo as the dealer might be having a lend of you for easy money although would be unlikely but not impossible. Best thing to do when you do have it all fixed up is in winter run the a/c for 5-10 minutes once a week this will prevent the seal breaking down when the weather changes back to hot extending the life of the seals in the a/c system.
I always run my A/C during winter once a week or so, because I am aware that the seals can dry up if it isn't run. But can excessive use of the A/C lead to premature failure? Bazztek's car isn't very old but it has done a huge amount of kilometres in that time. A lot of people seem to leave their A/C on constantly these days as well. Could 110k km's of constant A/C use lead to failure? Actually, maybe that isn't a valid point, his car would have climate control so the A/C wouldn't be on all the time. Okay, I'm out of ideas and just rambling basically. :whistling
Cheers for the replies guys, I'm also thinking its one of 2 things constant AC use for 100k or I'm not sure how long the car sat idle in the car yard... I do however run it at least weekly and always have with all my cars, I have owned a van from new for 10 years which had dealer fitted air con and never had an issue never even needed gas. Anyhow about the kays going by the favorites stored in the gps it looks like the previous owner went to the country a fair bit.
Most Dealers do not have Air Conditioning Specialist on their payroll. If you want an unbiased and factual assessment of the air conditioning, take the vehicle to an Air Conditioning Specialist. Will likely save you money - in the long run. Good luck.
Yep I did have taking it to a specialist in mind too, for the record I didn't take it to a dealership for a service I took it to my local mechanic workshop but obviously they don't specialize in AC either when he said he would have to remove the compressor and have it sent away I thought I may as well cut out the middle man and go to a specialist. Can anyone suggest one on the west side of Melbourne?
a new compressor for the v8 from HOLMART is only $439 may be worth ringing them to see what a v6 is worth, that's if yours go's bung, but take it to an a/c specialist for a test/inspection and then go from there, mine stays on most of the year round and I've got 150KLM on mine with no problems (not climate control)
I had the same problem on my VY. The AC was leeking oil but you wouldn't know it not to see it. It ran fine for about 6 months then it just stopped working. Cost me about $800 bucks for a new one installed.
Air conditioning pipes will eventually leak gas over time caused by the engines heat, vibration and rubbing, they can also go in the joins. Its just luck really; if you have a good run with a car's a/c system where it lasts for ages or a bad one; a couple of years. I've seen a 3 year old audi suffer from a leak and my old barina leaked after 12 years of faithful service. As has been said you should run your air conditioning sometimes each week to lubricate the main seal at the front of the compressor. If your air con is leaking you can just wait for it to stop completely (which might be quite a while) and then fix the problem properly or re-gass it and it'll eventually leak out again between the next 6-12 months. An air con guy can use a leak detector and pin point where the leak is, if its not the compressor.
Turns out after running dye in the system for a week there was no evidence of leaks and everything continues to operate as per usual, I won't be going back to that mechanic at least, sounds as though they were trying to rip me off. The air con guy did say to me most regular mechanics don't have much of a clue when it comes to aircon.
