    Ive been hearing a squeaky belt rotating kind of sound in my car. It stops when I switch off the AC. And somehow it has a connection with the clutch which I don't understand. When I apply the clutch the sound pops up.
    But this sound comes once or twice in a week only, sometime for short duration and sometimes throughout the drive . So the problem is when the service guys check it, there won't be any issue & later when I drive it pops up. What might be the reason?

    Ohh thank you...I'll ask the service engineer to check this. Car is already given for service. :) But how do you exactly know its the tensioner pulley that is causing trouble? It can be the driving pulley or alternator belt also right?

    I checked it in youtube. As you said its the problem with the tensioner pulley only :)

    Just a doubt...Is tensioner pulley & idler pulley same?

    They have this spray lubricant aerosol type with a long nozzle. If he sprays it on the pulley while engine running, the sound disappears immediately. If not there maybe some other issue. Please verify since it's not exactly cheap to replace only to find some other source of noise.

    Post feedback here. Best of luck.

    No, they are often mixed up. I doubt if they are applicable in our case. Best to ask SA about those as well.

    Cooling coil & O-Rings Replacement

    Today I got a call from SA regarding the cooling issue on my Linea 1.3JD. He said there is a problem with the cooling coil & it needs to be replaced. He said the gas is leaking & if he fills the gas for Rs.2000, it will leak within 3 days. Also he said the O-Rings needs to be replaced.

    The estimate quoted by him is 8k to get the job completely done with. My questions are -

    1. Should I check with some AC mechanics outside?

    2. Is the price correct for the job mentioned above?

    3. Is cooling coil replacement a normal thing?

    Just enquired with an outside AC mechanic. The price he quoted for the same job to get done is 6k. He said he'll be using the OE cooling coil. Seems like this is a better option. :)

    @kailasmenon2000,
    So what is the update on AC and the squeaky sound. What actions were needed to solve those.

    Thanx.

    Hi Kailas,

    I am experiencing the same issue in Palio Stile MJD. The Squeaking sound is noticed only while Car is Idle for some time.
    Can you please let me know how could you fix the problem. I will go to FASS soon.

    Thanks,
    Shashank
