Air Con Condenser rad for Gen 7 needed


Recommended Posts

When I've had it done on the gen6 I've always used a local mobile air con guy and he's been brilliant. Can test system, carries spare o rings and caps etc, will also replace parts of the system or pipework if needed.

 

There are a lot set up to do aircon but lots of them just do regassing. If you find one that does the mechanical side of it to they're really useful.

 

The guy I use covers west Yorkshire area so if anyone is around here let me know and I'll give you his details 

 

From what I've read Valeo and Nissens are OEM or equivalent and are what I'd use.

The driers are full of beads or small pellets of what are called molecular sieve and these filter out water vapour from the system. Water gets in because it can diffuse in through the rubber hoses, then it can start and corrode from the inside out. Except for the Gen7, the cars I've had all had a sealed unit drier with the sieve inside, but the 7 must use some kind of re-fill pack?

 

An AC system in good condition needs a regas about every 4 years and I take the view that I'm happy to use a good professional, usually charging ~£50(?) to do it. A pro will take 30-45 minutes to do the job (anything less is worrying).  Be sure to check that you get leak-indicating dye added.

How much mobile gasser charge?

 

On mine he tested all the electronic components individually, did a leak test to identify some seals had gone, replaced 4 seals I think it was, then another leak test and re gas. 100 quid Inc vat and worth it in my book, especially driving round recently in 30 degree heat with leather seats but ice cold air con

Odd iv had the gen7 for 8 years and when i first got it it waa 13 years old and ac did work but was never mega cold unless driving on motorway. Over time it lost its kick.

Iv got various cars over 10 years old that have never been regassed and are still cold.

 

Mums 2004 astra was regassed but didnt last a few months so has to be leaking. And leaks are usually from the condenser.

Also that dryer thing may be like a silica gel packet you get in boxes that ship out electronic goods to absorb any moisture.

 

Gonna get condenser sorted first before i go for a gas job. Dunno if they oil the system before or if i need to oil it up when condenser is fitted.

Job looks easy like changing coolant rad. Probably easier since no bleeding etc needed.

Bumper off job though.

 

As mentioned above if nissens and valeo is oem then im gonna try and stick with them for a replacement.

Yea on my gen 6 the air con has never worked while ive had it so well worth it to get it fixed.

 

The leak on mine was the seals where the pipework connects to the rad or condenser. I bought a spare rad just in case but the existing one turned out to be fine.

 

Think the common leak places are the seals I mentioned above, the rad itself or the compressor shats itself.

 

The oil gets put in with the gas when they regas it, all done together

Ahh thats the other thing i was gonna ask.

If changing the condenser do i just get seals that go on the condenser? Should i not touch the seals on the compressor side unless im opening up the pipes to the compressor?

From the sounds of it i should change all the seals compressor and condenser side to be on the safe side.

Also from reading around it seems nissens is oem for volvo. However if you go main dealer for nissens condenser you will get nissens made in Sweden. Aftermarket nissens is made in china depending which car its for.

So dunno...

seals on the gen7 are generally ok, main thing is putting a film of oil on them before putting the pipes back in - usually use the old compressor oil that comes out

In theory, they are legally obliged to show that the system does not leak before they refill it. That is because the gas is a powerful green house gas and there are tight restrictions on allowing it to get in to the atmosphere. So they put on a vacuum pump, pull out anything that's left in there and wait to see if they get a good vacuum showing no leaks. But quite how sensitive the test is to very small leaks is hard to say.

 

The oil gets injected in to the system as the new gas goes in.  In the past, AC specialists had a variety of kit, but increasingly they all seem to be using pretty much the same highly-automated units, but I'd still much rather have a specialist do the job than some bloke at one of the chains.

Just been googling about these cancelled purchases, and came across this:

 

"Another increasingly common tactic is for foreign "sellers" to use eBay to collect personal information. You buy from a fake listing, pay, then seller cancels the order with a lame excuse. Once they have your paypal user name, then they can narrow down the amount of tries to hack it, needing only a password, not both data.

 

I even had this occur with the same "seller" twice in a row.

 

I reported it, but like many other problems, eBay employees are too busy tooting their own horn to care."

Might be worth increasing the strength of your paypal pw just for safety...? :shrug:

 

A lot of sellers are middlemen. So they will create 1000s of listings of items that they dont personally have in stock but there suppliers have, when an item sells they then ship directly from manufacturer/supplier. This is why you might find the same item for sale by 10 - 20 different sellers but when you buy it, they are all out of stock - this happens with UK sellers as well. A member on here had it with ta22 shocks a few years ago. 

 

ebay doesnt give out email address's anymore to sellers, you get a forwarding email address instead.

This maybe why my condenser purchase seems to have been accepted okay 6 days ago, but there is no notice of it being posted yet...

Although these days of bonkers Brexit mess it could be delayed by import red tape (?)

 

Just as well it's not urgent :mellow:

I think we've gone from "just in time delivery" to "just too late". Lots of people stopped working it the height of Covid, and are now reluctant to return. Then there are all the pinged people in self lock down. I've had grocery deliveries for 12 years from Ocado... but not this week, or next week, or maybe even the next week :blowup:
