Green coolant in the compressor and worse still green a/c gas?

Yep, your idea seems to be the best thing to try. But if the compressor is fried, then there is no point in trying to get that to work as that will only damage the other components in the system, so proceed with care and insist to the MASS that NO WORK is carried out on your car when you are not present.

The attempt to restart the compressor after filling oil has failed and now compressor has to be replaced. For the time being I have asked them to convert the vehicle into non-A/c and give the vehicle back. I will decide the future course after ensuring the work is executed in capable hands.

Need guidance regarding expert A/c shops where I could get the work undertaken if possible. I am losing trust in MASS as the ones which are good are out to fleece with unneccessary replacements being done and those who are more transparent do not have the technical knowhow. In a dialemma really. Came across a good link which is informative from Sanden :

I cannot see how can coolant get into the compressor. Also. modern R34 is quite unhappy with any moisture in the compressor and becomes corrosive.

Either it is oil or serious trouble. Normally the A$$ for the ACs do a far better job. try one of these. Even if it is water you should be able to get a compressor overhaul far cheaper than 28k!

MASS guys have now said the compressor alone would be replaced. So I expect costs to be around 12000 + labour costs around 2000. I have already paid 10K advance and they have booked the compressor. It takes 3-4 days as now Maruti allows only zonal single point dealers to supply spares to MASS outlets. So M/s Automotive from Navi Mumbai has to supply the part.
I never said coolant has gone into the compressor. The oil which leaked from the compressor was green in color (must be using a dye). In all probability the compressor was heating up from the day my problems started and finally it got fried when the oil seal leaked and let out the oil.

Finally I got the compressor replaced today. Observations follow below :

a) The compressor had to be ordered from Maruti Gurgaon. It took 5 days for the consignment to be delivered along with regular spare shipments by road.
b) The compressor which went faulty was Matsushita and new one had a Panasonic label.
c) MASS flushed the whole A/c piping with air & nitrogen before pumping in refrigerant gas.
d) A/c specialist said that though Maruti uses Sanden for lower brands, Swift etc are getting Delsey brand A/c. Popular brand is Subros.
e) Cooling checked in idling condition with thermometer indicated cooling down to 5.5 degrees centigrade.
f) Total cost Rs. 1600 inclusive of labour and VAT. Compressor cost me around Rs. 12000.
g) They dont expect any issues now except that in rare cases sometimes there is a gas discharge issue with new compressors in which case refill will solve it.

Generally happy with the work of MASS.

Hello everyone,

Firstly sorry Emkay for hijacking your thread but since I have a similar problem I didn't want to open a separate thread for it.

I have a 2005 Swift Vxi which has done 62k kms till date. I have absolutely no issues with the car until recently. My car happened to be towed away by the traffic police as I happened park the car in a no parking zone. However, before driving away, I ensured I checked the entire car for damages caused by the towing process. After confirming that nothing was amiss, I drove off only to hear a minor but audible humming sound from the airconditioning. There is no issue with the cooling.

The sound appears only when the AC is on and when the compressor is operating. Once the compressor cuts off, the sound vanishes which means that the compressor is the culprit. After having the AC serviced and examined by my local mechanic, it was confirmed that the compressor is the culprit. He however told me that this is a common problem with a Swift once it crossed 55k kms and has told me not to bother about it as it is not affecting the cooling in any way. He also warned that there is a possibility of the compressor failing anytime or it could continue to work for years and hence to just live with it till (God forbid) something goes wrong and then have the unit changed. That would cost me a cool 15k!!!

What do you guys advise I do? Is this caused by the towing in some way? My mechanic says that the towing is not the cause of this problem but it has just by coincidence that it has occurred after that.

What type of hum? is it a high pitch yeeee or a low pitch ennnnnn?

If its the latter & if it is pulsating, the pistons are on their way out. In this case, the compressor will slowly lose its compression capability & will ultimately stop cooling.

If its the former, check the comp clutch & its bearings. The compressor is probably allrite.
