According to the A/C mechanic at Kropex, this is a common problem with Optra. Just got back the car, total damages Rs 3800. Cooling is fine now.

Just gave my 2004 Optra 1.8 LS to the dealer for a running repair. How can you identify if there is really a suspension problem for the Optra? I do not feel anything in the riding comfort. But now at 68K kms the dealer says suspension is due for overhaul. What would be the approximate cost of it? Further Optra's are said to have independent suspension for each wheel and how does the job differ from normal suspensions.

A few other problems I am facing. Just gave the car yesterday to the dealer to fix this.

1. Oil leak around the engine block (probably broken gasket). How can I make sure they do not take me for a ride? Any help/advice is appreciated.

2. Bad pungent smell coming into the car after the A/C runs for about 30-45 minutes. Could be the leaked oil getting heated and passing through the vents or something. Any idea on what else it could be ?

3. Idea of using K & N filter in Optra ? Would it really make a difference in mileage or performance?

You don't need to do anything on the suspension if there is no problem.

For the bad smell get the A/C cleaned deoderised. Any car saloon like 3m etc should be able to do this. The reason most of the time is fungi formation.

On using K&N you might not see a significant growth in mileage, however you are sure to get more power.

Thanks a lot for this thread. It is full of useful information. It was one of the more influential threads in confirming what a wonderful car this is.

The change in turbo kick/spiked power delivery, was rather curious. I had had a few TD's on the same car before purchase. It felt rather different in the third TD, which I reported here (Choosing a Spacious Diesel Sedan upto 12L). It was a BS4 variant. If one wants the rush, one can still feel it. More details in posted here (Finally! “Driven!” & “Chosen a Diesel Sedan” – The VVS Magnum (Chevrolet Optra)).

The change in the steering feel is strange again. Have found this car to be excessively sensitive to tyre pressure. Do you think it could be, that the tyre pressure was inadequate? I find this car to be behaving quite differently with a change in pressure - both handling in general and also the steering feel.
Cheers buddy !!! I'm glad this thread helped you out. About the BSIII & BSIV engine response - Definitely there was a noticeable difference.

Steering response - I did not take the tyres & tyre pressure into consideration so that have might have contributed to the difference I found.

Has anyone here faced a similar problem earlier?
Buddy service costs are average. Have done 72k till date.

Normal services ~ 3k.
AC Repair once around 40k ~ 5k
Suspension / Shocker replacement / repair till date ~ 30k
60k service ~ 15k T. Belt + other charges. Cannot recall the break up

Right now AC cooling has gone down again. Another 5k I guess.

Lights inadequate & OEM Tyres requires immediate replacement. Turanza's have kept me very satisfied on all aspects like control & braking. Replaced around 40 k & I think I might be able to squeeze another 10k out of them.

Any pointers on AC Cooling reduction?? Gas top up?? Local mechanic quoted 1700 with gas top up and cleaning without opening the dashboard. Auth. will charge not less than 5-6k but will remove the dashboard & service it.

My car has done 64k and not had much issues. Service cost is less than my Hyundai i20 diesel. Last service I had to get my rear shockers changed and total cost with service cost me 14k. T.Belt is due for change at 60k but still not have got that done.

Question: How important is to get TBelt change on time or can it be pushed for later?


I am also suspecting my front shockers needs to be changed soon and dont want all cost to come together. My car has not given me any major issues till now but this regular changes are coming now. In June it will 6 yrs old.

I have also noticed from last 3 services I am asked to get brake overhaul done which cost around 500-600/-. Not sure if its required every 5000k.

Ppl, ran my optra into some rocks and punctured the AC radiator/condensor. Its the size of a 2rs coin. I took it to kropex, singasandra. They said that i'd have to pay 21k for the replacement! So have decided to have it repaired. Can anyone point out a ac condensor repair guy preferably south bangalore who you've been to?

How old is the car? If its covered under insurance, why don't use it to buy a new condenser. Repairing is not recommended, since it holds high pressure gas and will give away sooner or later. For peace of mind sake get a new one.

Insurance is third party :-( and just paid 45k for my Nano's accident repair. So looking for a stop gap until some cash frees up.

Update : I called Aditya A/C services, koramangala. Over phone he told me that he'd change the condensor for 6.5K. But when I went there, he said since its a diesel optra, the charge will be 12K ! I'm going to post this in the technical section for any comments.I am not sure why the condensor will be different between the Diesel and Petrol Optra? Any takes on this?

Any takes on this?
If the system is different prices may vary. Call up Chevy workshop and speak to spare parts section. They should be able to give you the info over phone.

Hi,
A friend has an Optra Magnum Diesel which has the same issue with the AC. The effect has come down considerably and the back seat passengers are roasted alive. The AC seems to have a mind of its own. It is bad in the city but and totally underperforms the moment we hit the highway.
The Chevy guys don't have a clue and recommend replacement of every related part, compressor and all.

1. How did you solve your AC problem ?
2. What did you do about the dismal headlights ?
3. Any suggestions to solve the extremely low seating at the rear ?

Hoping to get your valuable suggestions

The car drives like a dream otherwise and the owner is loath to dispose it off.

1. Replacing the compressor & cleaning the condensor was the only solution to the above problem. Mine had the exactly same issue. Soon all the cooling will wear off and that is the final solution.

2. Nothing done yet. Really have no idea what to do.

3. No issues as such there.

There might be no need to change the compressor. There is a compressor pressure valve that needs to be changed. I had the same problem with A/C earlier. After changing the pressure valve at Kropex the cooling is fine. I spent about 3800 for the valve fitting along with labour and gas.
