Air conditioning refresh

Card Drama Nonce · Jun 24, 2024

Right, my aircon hasn't worked since I bought the car and seeing as we get proper summers here in Poland I really would like it to work.

My only clue is that it's missing? some seals or something, which a mechanic noticed when he pulled my engine out to do the belts and a clutch.

Something happens when I press the A/C button in the car so I presume something is engaging.

I've got myself what I think are all the correct seals to replace everything, and also some oil which is apparently required. Obviously I'll take it somewhere to have it pressure tested and re-gassed afterwards.

Explain to me like I'm an idiot (which shouldn't be hard) which pipes need taking off, how I remove them, is removing the bumper enough to access them all, how I check the oil level, and where do I fill up the oil?

Be prepared for a fucked condenser

As above id get a condenser for it as they are cheap.

You have 2 lines coming from the bulkhead to the compressor and condenser and then one pipe linking the 2.

There are various size oring seals on each joint (I just use universal kits with loads of seals in a box)

Id replace the condenser and the onrings on those pipes, then just leak test the rest as very rarely have I seen one leak, it's always holes in condensers.

A garage will then leak test it using nitrogen by pressuring the system and spraying soapy water over all the joins looking for bubbles, if good they will then vacuum and recharge the system

I've reinstalled the whole airconditioning system again myself on my Clio and it's pretty easy.

As above make sure to have a seal kit handy and some pag 46 oil. Clean connections, oil seals and put everything together as it came out. Don't over torque the bolts that hold pipes together.

Replace condenser and dryer at the same time which does require bumper to be off.

I believe a new pump comes prefilled with 150ml of oil and part replacements come with specific oil amounts (30 for condensor and 15ml for dryer rings a bell). I think I just dropped 200 ml in and bolted it all up.

Reinstating air con

My 182 had its air con / climate control removed by its previous owner. I’ve been told that the compressor etc are still all there and it just needs the rad and pipe work connecting back up (which I’ll need to source). Is it as straightforward as that? Never worked on air con before so any...

My last post in there has some additional info.

Oil is automatically added during gassing.

Hopefully you’re not still cooking and you’ve now fitted this?

Took this bolt out but the thing won't budge 🤔
I've tried hitting it with my handbag to no avail

Should just pull out once the bolt is out. Get a bit of heat on it

JamesBryan · Tuesday at 2:51 PM

Get something in there to break the seal, flat head screwdriver or similar.

Card Drama Nonce · Tuesday at 3:04 PM

Success! Tempted to just take it to a garage now 🤣

JamesBryan · Tuesday at 3:06 PM

Have you got new o rings for the pipes?

Card Drama Nonce · Tuesday at 3:07 PM

What seals go where then? I've got these ready.

There don't appear to be any seals to replace on the pipes I just disconnected 🤔

JamesBryan · Tuesday at 3:10 PM

The top packet are ones from the AC compressor i think.

The others are for the various pipes.

Those pipe have got seals on, they just look like metal 😂

Have a dig at them and they'll come off.

I was expecting crumbly rubber, I assumed they were bits of the pipe or something 🤣

Hmm, that one definitely looks like metal now you've scraped away at it

JamesBryan · Tuesday at 3:28 PM

Mine looked like that but a seal came off eventually.

Is there a seal stuck inside the rad?

Card Drama Nonce · Tuesday at 3:28 PM

Yeah, apparently pliers aren't a substitution for mole grips 🤣

No, nothing at all. I'm starting to think these were the missing seals mentioned earlier lol

Suprised that held any gas at all with no seals 😂

JamesBryan · Tuesday at 3:40 PM

Apologies, it does have that metal lip which the seal then sits against.

Was convinced mine never, but i must be wrong.

Louis · Tuesday at 3:47 PM

Isn't that the oring?

Well the good news is it's all back together. I filed away the evidence of me trying to remove the metal ring with rusty pliers and stuck some o-rings on there, coated in a bit of PAG46 oil. Also replaced the compressor seals while I was there, which were actually still attached which made a nice change. All lubed up and reinstalled.

The only casualty was this bolt which fell out when I was loosening one of the bottom brackets, as the radiator had turned to dust at that point. Ah well, 3 bolts is better than none 🤷🏻

Also found what I think is the cause of my oil leak, or at least one of my oil leaks 🙃 (what is this by the way?)

Bit annoyed that my phone died before I finished, so you'll just have to trust me that I put everything back together and didn't just throw everything in the boot and go back upstairs 🤣

JamesBryan · Tuesday at 4:45 PM

That bit leaking is the power steering pressure switch/sensor.

If you clean it all off, you should be able to tell where it's leaking from.

Does that mean I've got a power steering fluid leak as well 🤣

Pretty common tbh

Card Drama Nonce · Thursday at 10:49 AM

Am I right in thinking the compressor won't engage on an empty system?

Brigsy · Thursday at 10:50 AM

Yep compressor wont cut in unless pressured up.

Card Drama Nonce · Thursday at 10:55 AM

Right, fingers crossed then 🤞🏻

Card Drama Nonce · Thursday at 11:12 AM

Pissflaps. Still leaking from somewhere.
What other seals are there? I did the ones in the compressor and the condenser. What did I miss?
