Car Problem : Ask the Expert

I have 2001 model Santo. When the engine is in cold condition (for eg: starting after a gap of 4 hrs) and if I start and switch on the AC, the AC runs. But when I move forward and change gears (1st to 2nd or 2nd to 3rd), the engine switches off. But when the engine is warm (i.e after about 15-20 minutes of running) then there is no problem and AC and engine runs smoothly. Also if I do not use AC, then there is no problem of engine switching off even if it is in cool down condition. Please tell me whether the problem is with the engine or AC?

Asked by Rahul for Hyundai Santro

Dear Rahul,
when we switch on the AC the acceleration of the engine requires to increase about 10 % through a sensor . it seems the senser to increase that acceleration is not working and if this problem u r facing only on ac than get the same checked by scanner at the workshop and clean or change the same . also pl note if your car is running on cng than the acceleration to be increased otherwise ac trips.

I have a Maruti 800 MPFI car with me which am about 10 year old. It’s fitted with CNG, but due to prolonged non usage the CNG kit system is not in working condition. The gas flow is not consistent. Kindly suggest what needs to be done in order to make it fully functional.

Asked by Sumant for Maruti Maruti 800 MPFI

Dear Sumant,
first of all get the regulater of the cng kit overhauled and check the wiring and gas filling valve and leakage from the pipes cylinder and other joints you will get it functional if that was working properly when you had stopped using cng.

I have 1992 model maruti esteem car., which have a problem of tyre.,means if car runs just for 60 kms tyre wil get cut and Ac is not working., suspension is also not in good condition so can you please tell me the cost for repair that..And what is the problem with that.

Asked by Sanjeev for Maruti Esteem

Dear Sanjeev,
your vehicle has all problems except engine as per your query . the tyre worn out problem is because of wheel alignment or the vehicle is accidented from the lower . the cost of the repair for the above problems is approximately 10-15000 Rs. Depending upon the ac compressor condition. Apart from the above problems please see whether you have got the vehicle fitness (which is required after 15 years and every five years after 15 years) done or not, if not than that is the more dangerous and illegal to run that vehicle on road .

I have Alto LXI 2004 model in good condition, and i fitted CNG on 15th Dec 2011 and my daily drive run is approx 100KM, after fitting the CNG the car gets overheat suddenly with a random interval of 5-7 days any time. Maruti workshops changed the radiator and so many parts and rechecked the car 2-3 times but didn’t found the fault. Please help me regarding the same.

Asked by Prashant kumar for Maruti Alto LXI

Dear Prashant,
cng if fitted properly with all genuine parts and from the government authorized fitment centre is no way the reason for the heating of the car . it might be matter of chance that your car is getting heated or if your vehicle has run more than one lac it may require head overhauling . there are so many reasons for heating if radiater is changed and other parts also by the mechanic .i advice you to change the workshop as he could be hiding something to save his face . sometimes for higher pickup some mechanics change timing of the vehicle which is not recommended.
