Default Zen AC compressor change (R12 to R134)

Hello everyone,

AC is the main thing while driving in Mumbai, specifically during summer, I own a ZEN which has a 80cc compressor which is inadequate and the cooling is not that good.
My ZEN AC has gone from bad to worse, it was making a lot of noise when switch ON and was heavy on zen engine and add to that , the gas was leaking, I had to top up every month, still no cooling and average was going down, decided to sell the car, but then who will buy a zen with bad compressor. The only option was to change the compressor.
MASS quoted 21K for only compressor, other road side shop quoted 14K for the compressor. To top it all the gas used in zen ( R12 ) is banned and not easily available. Frustrated called my cousin who directed his AC mechanic to visit my house and have a look at zen compressor. He too advice me change the compressor. I made up my mind to spend around 15K just to get the AC working.
I said to the mechanic “ Kitna kharcha hoga” he said “saab -------- hoga“ (I will tell the figure at the end)
My heart skip a beat, I again asked him “ Kitna?????” “ saab------- hoga”, Etna main hoja ye ga?? I asked him. “ Haa saab” I agreed to change the compressor.
After a week he calls me and said that he has the compressor ( second hand ) and in top condition, I asked him to come on Sunday to install it as that I can personally see what he is doing.
He changed the following
Compressor ( 80cc which uses R134 gas ), he purchase the compressor from Kurla, Mumbai where all the cars are scrapped.
R134 gas
Evaporator bottle
A valve inside the dash board
Total bill 5000 K
yes you heard it only 5000K and my AC chills now and is super silent, average has now is 15.5 in city.

I do hope all zen onners are benifitted by my experience.

just 5000... excellent man... the evaporator bottle would have be around 500. the gas another 1300, the valve (btw its called expansion valve) that another 800. the mechanic labour...say 500?? ok so 500+1300+800+500=3100!! 5000-3100=1900.. damn good man. the mechanic dude is surely a nice guy and so is your friend who introduced him to you. so you can chill now in your new AC. lol

cheers

Hello Uday .
Your experiance with changing the ac compressor is really an inviting one to most of the Zen owners in the forum . Because the zen ac was always a pain for most of the owners . Well I am one of them too .

Would like your help in some of the topics mentioned below .
1 - is this new compressor that of zens ?
2- Which years?
3- I also would like to do this change , do you have a contact in Kerala ?
( I know I being too optimistic in this 3rd question ) .

Have fun with ac on :-)

wow just 5k, sweet deal you had! Can you please check the compressor for us and post details like model number and brand of this compressor? Was it a direct fit or required modification in pulley and mountings etc?

sure will PM you the no.

Guys,
Zen is one of the best cars to drive, problem is only with AC, I will let you know my experience

I own 2002 MPFI model LXI, ac compressor is just enough to cool the cabin when the car is new, as the years progress the cooling comes down. the compressor as it ages, starts to be noisey and with due course the noise becomes greated then the engine, and this loads the engine as the compressor starts to seige.
Two things can be done, repair the compressor or change the compressor.
repair is possible if the ac mechenice is very good, in my case I did repair the compressor but then it behave good for one year and then back to the noisey thing.
To replace the compressor it will set you back by 20K, but then who will put that amount in to a car which is discontinued, only fesiable solution is to install a second hand compressor with uses R134 gas ( R 12 is banned and not available).

what my machenic did was to purchase a second hand compressor from Kurla scrap yard. He bought a 80cc zen compressor which uses R 134 gas.
Then he removed my zen compressor, flushed the complete system changed the receiver/dryer bottle, changed the valve inside the dash board, and yes the ac is just fine, cools very good now.

I shall provide the model no as soon as have a look at it. I think its subros brand but let me confirm it .

Maruti was using R12 gas in Pre-2003 Zens, I too own a 2002 Zen. I sorted out the AC problem in the similar fashion.

Can anyone confirm cc capacity of R12 compressor in Zen

Looks like he pulled the compressor out of a crashed vehicle and hence the low price. One cannot expect ready availability or fixed prices in such cases.

You are lucky you live in Mumbai where the summers are humid. In Nagpur where I live, even the newer Zen compressor fails to cool when the temperature hits 45 deg. I too nearly came close to selling my Zen VXi this summer because of the inefficient AC. Now that the rains are here, the AC works fine.
