Seized a/c compressor

Featured Replies

Hi guys just signed up so forgive me for mistakes. My ac compressor seized so I've bypassed it. Got a crazy quote from skoda of close to €1000 euro for one fitted by them. Is it a big job to get one in a breakers and fit it yourself. Again guys sorry if Im putting this up in the wrong place. Im sure someone will let me know. Cheers guys from Ireland.

I fitted a breakers yard one to my MK1 (cost £30 delivered) and it was dead easy.

 

I have problems with the one on my MK2, I have already unbolted and pulled it away from the engine block to replace the alloy mounting bracket, maybe it was that which caused mine to fail, anyway it was just as easy to remove although I did not remove the pipes so as to keep the gas in the system but they look just as easy to remove so the job should be very simple for you.

 

I looked at S/H pumps but they were all expensive compared to a new one from China for £122 delivered, many were a lot more money.

 

When my old one comes apart I may find that it has seized but the shear plates are intact, I ran my MK1 for a decade with the compressor bypassed and the pulley just running free without a clutch before having the means to replace it, it sure was nice to get the A/C back after all that time.

It doesn't sound like an awful job to do, as long as the compressor you get in the breakers works.

 

In order to be legal, you should probably get your local aircon place to take the gas out the system before you do the job as it's quite likely illegal to release the gas in your aircon system into the atmosphere, as well as not being good for the environment. Hopefully they won't charge you to do it as you're going to be going back there when the job is done to get the system leak tested and regassed

I got one of these. Fitted and works perfectly. Quite easy to fit.

As mentioned above, I got the local tyre fitter type place to remove the gas (FOC) and went back when the new one was on and it was about £50 to fill it.

The place that recharged mine offered that to me when I replace it, trouble is they are 30 miles away, the pump turns permanantly and I am concerned about lack of lubrication, not on the old pump for the return journey but after I have fitted the new one, I dont want it to wear or seize before getting it back to them for recharge.

 

Did your new pump have lubricant in it?

 

Anyone else doe the same?

 

Aside from the environmental concerns R134 gas is hugely expensive something like £50 a kg so recovering 525 grammes from my system is in their interests.

Just wondering is it a simple unbolt everything and bolt on the new one.

Yes, 3 bolts, one electrical connector and 2 hose couplings.

So is it ok to remove it and drive without it till you find a replacement.

Oh and do you need any special tools 

I dont think you can remove it as its pulley is needed for the auxiliary drive belt which also drives the alternator.

 

I wont be removing mine till I have its replacement.

 

If I have the above wrong someone please correct me.

 

No special tools needed to my knowledge although I have not yet removed the hoses, just pulled it away from the engine to replace the casting it is mounted on.

You should only really remove once you are ready to fit the new one, you don't want to get any foreign material in there and you also don't want any moisture. If the system is ever open to atmosphere you really need to change the dryer unit as well or your air con won't work as well.

You may be able to remove it if you got an auxiliary belt that was shorter for cars without aircon. Not 100% sure though.

You got me thinking so I checked for our '07 tdi motors, and you're right!
This diagram show the two alternatives and includes the part numbers.

 

I'd change the air conditioning solenoid control valve whilst you have the system de-gassed. Common fail point but cheap to buy.

Already done that with high hopes that came to nothing, valve cheap, regas expensive.

 

Sorry, though the reply was to my aircon thread.

 

If the OP's compressor is seized then changing the control valve aint gonna do a lot for him.

Edited by J.R.

AND you need to have the system flushed too, to will be full of swarf and debris no doubt, oh and change the condenser if it's got the plastic nut, otherwise it's just the drier.

 

Hope this helps,

Fitted my cheap Chinese compressor, had gas and oil sucked out beforehand and refiiled/recharged afterwards for £20, aircon and climate control working perfectly, checked all parameters with VCDS the next day and all is good.

 

Olc compressor in bits on my bench, seems in perfect condition, very uncomplicated, if the gallerys going to the solenoid valve are not blocked then the failure must have been the original and the replacement solenoid valve, there is nothing else that it could be, it looks as good as new after 122K miles.

 

Original problem was G65 pressure sensor, I think the inactivity caused the solenoid valve to become sticky and the new one despite clicking and moving does not work unless they are both the wrong type or the passage is blocked, will check both later.

 

Good news is that it was all so clean I have no worries about particles and debris in the condensor and drier, pipes were only disconnected for 5 minutes so no moisture ingress.

Moisture isn't a major issue, but off course its better not to expose the pipes and all circuits to normal air.

Dirt and dust can be a bigger issue.

 

If there is moisture in the system (which there is, since the humidity is never 0): That's why you need to evacuate the system with a vacuum pump

 

When a system has been open for a long time, I highly would recommend a double (or even triple) evacuation, Run the vacuumpump for 15-30min, recharge with nitrogen and repeat.

 

A vacuum pump lowers the pressure in the system, so the boiling point of water decreases. All moisture will than be gas (instead of liquid) and the vacuum pump will remove it.

 

My system was exposed to air for over an hour. (I had to replace the condensor). I did cover the AC lines off course, but still, it won't be 100% close 

 

As for the dryer, on my O2 it was fixed to the condensor, so it couln't be replaced seperately. But in my case it had to go anyway, since it was leaking on the plastic nut (which is a common issue)

 

If you want it completely done, replace as mentioned the valve as well, and while working on the front, you might want to add some cover to the grill as well to prevent debris/stones hitting your condensor (There is a partno somewhere on this forum for some mesh)

Below is a link to the mesh that many people have used (including myself) to protect the condensor. I was advised to fasten it to the outer grill with small black tie wraps. You have to look very hard to see them once fitted. I was amazed too how much crud, including bits of concrete, had hit the consensor and fallen down in front.

So many people have used this insect fish net for condensor protection that they now have car grill pictures on their site.

Thats mesh is a great idea. I've noticed little chinks or broken fins on my condenser . Will be getting the mesh or something very similar. Top advice thanks.

Hi guys .Sorry for the long delay in my reply . I got a compressor from a breaker after a long search for €80 and got my mechanic to put it in . It was €60 euro to  re gas. My old compressor had seized so while waiting for the new on I bypassed the ac pully by using a shorter belt. Cheers guys for all the replies
