    Default Mehran over heating

    Dear all i am facing a weird issue. Car has started to over heat and the needle crosses 50% mark with and wothout ac to reach 80% mark and stays there and then slightly deflects back and then comes again to 80 mark...mehran's green zone is also till approx 80% and after that the red area starts. Car doesnt reach that red area. Radiator is serviced and its of original Loads copper one. Fan was auto but mechanic made it direct on my recommendation due to this over heat. Tstat is removed. Car was behaving extremely fine with ac till 4 days ago. My mechanic saw and checked in detail to conclude the gasket has been weak - but how come car doesnt reduce even 1mm of water? I was not satisfied and went to another mechanic who said all is ok, no gasket issue at all just have your front of rad and condenser washed as it seems choked....please suggest as i have to travel around 40km a day in congested khi and cannot afford overheating and non ac travel...

    Car is 1998 vxr cng and just 29k drive in almost brand new condition..

    See the pic of temp needle

    Get your radiator checked/serviced. Fill it with coolant and not with tap water.
    Running the radiator fan direct is never recommended.
    Almost everyone in Pakistan is doing corruption to the extent they can. Our leaders are doing at the level they can do. So why should we complain?

    Keep using this oil. Nothing wrong with it. Get your radiator serviced and also check fan speed. After service fill the radiator with anti rust coolant.
