replacing aircon compressor
- Thread starter Moet32
- Start date
Hopefully aymen will comment soon as i know he replaced his when i found it to be faulty. Its advisable to replace the drier when ever a refrigeration system is broken in to, iv never replaced an automotive drier so not sure how easy they are to change or if its part of the condenser.
Moet, what engine do you have?
It is true, I replaced mine recently however I have the VE (110hp) diesel and my AC pump is located at the bottom of the engine so I could access mine from under the car very easily.
For mine, I did the following:
1 - Remove engine tray
2 - Remove the Auxillary Drive Belt (alternator belt)
3 - Remove the two pipes on the back of the pump (BE CAREFUL HERE, although kwikfit emptied my system there was still a little bit left and the pipe exploded off the pump, luckily my face was not near as it would have really hurt. Just make sure you keep body parts away and wear gloves)
4 - Remove the two 16mm bolts from the AC pump and extract them.
5 - Use the leverage of a screwdriver to assist in removing the pump.
REFITTING is the opposite however Firstly, you need to look at the new pump. Where the bolts go, there is a nut located in the pump already, it is round. You need to re-seat that nut. I did this by inserting the bolt most of the way, then stand the pump on its end and put a socket over the nut (slightly bigger as you are just supporting the pump with this. Next, use a hammer to hit the head of the bolt so that the nut is pressed into the housing. This explaination is a little confusing, if you need more help let me know.
It is not that difficult, just be careful as it can be dangerous especially when taking off the AUX belt and taking off the AC pipes.

As for the drier, it is easy to replace once the system is open.
You can buy it from EuroCarParts or CarParts4Less or similar. It is located behind the front right headlamp and is a vertical cylinder with a pipe going in the top and out the bottom.
The clamp around it is the most irritating thing.
You might also need new O-Rings, you can get these from SEAT directly for about 50p each, they are purple O-Rings which could be something to do with the R-134A Gas.

To make sure the ac system is empty you can stick a little flat blade in the service valve a depress it slightly, even when you recover the refrigerant there will be sone still in the oil which will boil off and represurise the system.
Isn't a very big fine if you get caught releasing the gas into atmosphere?

Yes there is but as I took it to kwikfit and asked them to empty the system professionally I believe I am not in the wrong if any remaining gas enters the atmosphere. It was only a tiny amount as well but I still see your point. I think it is pretty hard to evacuate the entire system but I'm no expert.

I agree with you. Chances of getting caught are im but I was just enquiring.
