I am contemplating replacing all of the O rings on my air conditioning system.

Is it possible to do whilst the unit etc is still on the car?

I guess there will be issues with access.

 

How many out of ten in terms of difficulty would this likely to be?

Are you losing pressure, is that why you are changing them?

Yes mate.

The last time I had it re charged it seemed to last all summer, but over time it looks as though it has gradually lost the refrigerant.

Can't see any visible leaks though, so I though I would start with the seals.

The place where you get your refrigerant done should be able to add special color to it and you can see with special glasses all them leaks

I have one at work, u put a dye in, use glasses and a special light.

most garages should be able to do it.

I have had a couple of places look at it, they both said it should be fine and took my money!

I just think that they were not capable of fully repairing the system due to the complexity so I am a bit reluctant to let anyone else do it.

Would like to solve it myself to be honest once and for all!

I reckon the ones that go through the bulkhead would be a bitch to get anything on to turn them mate. I would definitely want to try to source the specific one/ones that were leaking before getting involved in that

So you've already had dye in the system but they couldn't find anything? I'd hate for you to change all the o rings only to find it still does it, and there's a leak in the condenser or something!

I know what you mean Eggs, I was thinking of renewing all o rings from the bulkhead onwards. I have managed to undo the two at the bulkhead itself, just want to understand how to access the rest. Would just like to know how to go about it and how much work will be involved.

There are a couple by the condenser which will be difficult as well, You might get in through the nose panel or from underneath, I can't tell without looking at the car.

 

Do you know where they all are or would it help if I took some pictures of mine tomorrow as the engine is out but AC is back in?

Hi Baz, that's right mate.

Both said that the system was free of leaks. I thought of the o rings out of desperation as I do not know where the most likely places might be to be honest.

Hi Eggs,

I have had a good read of the manual and have gained a basic idea of where they seem to be, but if you would put some pictures up when you have time that would be a great help mate.

It could also be the schrader valve where the gas is filled, they can often leak

Cheers Baz.

 

I hope to have a good poke around at the week end.

Do you think it is possible to remove everything pertaining to the air conditioning apart from the compressor without a major strip down?

If I do manage to strip everything off, will it be OK to leave the compressor in place and disconnected from the pipework for a while?

Or will I run the risk of damage to the compressor itself?

Bumpty bump

 

ps

Eggs, is the offer of some pictures still on mate? no worries if not. I can imagine folk having better things to do in this glorious Zed wheather.
