Im going to Suraksha today, the one on Hosur road next to grave yard, for steering play issue.

Any particular guy to meet there? Any references?

How is that place to get my AC serviced or should I go to Aditya AC guys in Rajajinagar? I even wanted to upgrade the AC fan to get better air if its still less after servicing. Which model's fan I should go for?

Speak to Lokesh he should be able to help you. Reg AC if its a reliable shop i would prefer and independent specialist. Fan upgrade am not sure how feasible it is since the box has dimension limitations.

Smile AC back to Perfect!

I went to Suraksha. He did a test drive. Said play is very minor, nothing to worry about. Rectifying might take a day. Its complex task to pin point the issue.

He said Windshield can be replaced under insurance. Howwever I need to pay ard 1.5K for misc.

So i left. Person who attended me was Mr Prakash till I remember.

Then I got my AC serviced today at Aditya AC Rajajinagar.

Things noted were low gas.

Things done: some box under dash was opened. He cleaned condonser with a sponge and water. Then cleaned the box/cover.

Topped up the gas and waited till cut-off by putting a thermometer gauge pin inside the grill and blower at 1st point. Cut-off was noted at -1.2C on thermometer

I saw ice formation on pipe under the hood. He said excellent condition AC.

I kept complaining for blower power. He said nothing can be done. This is best as per Zen.

Also thing to note here is. Mine is R12 compressor. But I was recommended to top-up with R134. So I went ahead.

He didnt do any neutralizer, soap cleaning, blower cleaning...not sure, why

After I left from there, i left AC is much better by cooling as well as blower power. I can now feel the cool wind on my face!

Total cost 800/- with bill! :-)

What?? I hope you are joking. R12 & R134a need different systems and cannot be substituted AFAIK. You may end up permanently damaging the compressor. Please recheck!!

i agree with Zen2001 here. I too have the R12 compressor and wanted to refill the gas. I was told they have been instructed NOT to refill the gas. i was recommended to upgrade to R134 system which was quoted 12K. I said "Thank you" and went to the local garage and asked them to refill the R12 gas, which he did at a cost of Rs. 350/-

Thumbs down Problem with 2001 Model Zen LX

I am having a Zen LX 2001 model. I am the second owner of that. I got it at 39000km on odo and now it is 47000. Now the vehicle is giving some odd sound from engine as if its some super car. Also the average has reduced to some less than 10kmpl. It was previously giving some 12 to 13kmpl. I had done the servicing from MASS. They told that Tappet was jammed repaired it. Also spark plugs and filter were changed, but still its giving less average. Also now its difficult to start the vehicle at noon time when temperature is high. I have to crank it again and again to get it started. Also soem slipping noise is coming from the engine bay, seems to be belt slipping. Kindly help me out in deciding what to be done on the vehicle.

It would be a good idea to check if the radiator fan is working. It works with the help of a thermosat, when the engine temp reaches a threshold the fan starts. Please check and revert.

  1. Does the exhaust sound racy?or loud?and do you feel the pick up has increased?If yes,then it could be a leaky exhaust,and this can contribute to low mileage
  2. Is your car carburetted or mpfi?If it is mpfi and it does not start,I am afraid you need to get the engine scanned.If it is a carb,switch on ignition,press and release accelerator once and then start on idle without pressing accelerator.It should fire without any issues.
  3. If the noise you hear on starting is some "keeeeechchchch",then one of teh belts is slipping;check condition of belts and adjust/replace.

1. I dont find any exhaust sound, But the engine itself is loud, somebody told me that its common with all maruti vehicles when it becomes old.
2. My car is carburreted (its LX, not LXi). I have tried that too, but it didnt work. also once it starts, and when the accelerator pedal is pressed, it vibrates and stops as if it is not getting fuel properly, a missing can be felt, then if i floor the accelerator, then it raises and it becomes ok.
3. Yes the noise is that only, but i can feel power loss when that sound comes, and once the sound stops the car is picking speed.

Also i forgot to mention one thing, The power of the car is felt low as a whole. Its difficult while overtaking and all. I had replaced the fuel pump inside the tank once. Is it something related to that. But it was working fine for quiet long after the replacement

It appears that you are being taken for a ride - replacing everything need not be the solution always.

Any chance of your driving to Surat?if yes,can lead you to a 100% solution.

Dear Harikr,

39000km on a 10 year old Zen sounds like a dream, doesn't it? Looks like you unfortunately fell for it (although I wish I'm wrong). I would have expected a trouble free car of that age to clock atleast 75000km, but then that's just me!

Your options as I see -
1. If you bought from "True Value", take up your issues with them. True value cars also come with certain "limited warranty".
2. Get the car checked by an independant and reliable mechanic whom you can trust not to take you for a ride. Ask your contacts and research this time.
3. Since you have noticed the problem after driving 8000km yourself, is it possible that it could have something to do with the way you drive?
4. Obvious problems and simple solutions - The old carb models have a lot of rubber "pipes" running to & from the carburettor. A leak/loose/cut pipe can result in any/all of your problems. Check and let us know.

Default Zen Decarb

Zen Sludge Issue:

What are kinds of MASS known ways of sludge removal for Zen Carb model?

I went through TATA decarbonation page : Tata Motors Customer Care :: Decarbonising & Engine Flush

Can these be done on any cars? Rates arent that expensive.

Any Zen owners done decarb? Which one? For how much? Post decarb experience?

Hey I have a similar problem with my Zen. Its a 2001 model, the AC is jus blowing air at normal temprature, took it to the M.A.S.S. to get the gas filled. They say that I need to upgrade to a new system, and quoted a 8-9k for this.

Do you suggest I go for the R134? What are the complications if I do so?
Or I simply go to a local garage and jus spend on filling the gas?
