    Default overheating problem >> radiator fan

    my car is an optra, year 2005.
    recently im having overheating issues with it.

    i was told that the radiator fan is working on 2 speeds, low and high.
    after it reaches a certain temp, the radiator fan should switch from low to high speed.
    unfortunately, my radiator fan is not.

    the bigger problem here is that i brought it already to a nearby casa.
    they cant fix it because they can not find any error everytime they run the diagnostic test.
    the sensor is reading the temperature correctly.

    any advice folks? TIA

    Sir, saang casa po kayo nagpunta? Chevy do have an expert guy with regards to diagnostics and he carries this particular suitcase like gadget in his car all the time. Please inquire from the casa if he can do some diagnostics on your car. If you need further help, please send me a private message, thanks.

    @supremacy,
    as far as I know, the 2 radiator are not running at the same time.
    yung 1 ang lagi naka ON and running and the other auxillliary will only run
    pag nadetect ng system na mainit na at it will automoatically run and switch off again.
    ON and OFF yung isang fan.

    start your engine and open your engines hood.
    observe while in idle, you'll see that 1-fan is running (i think its the one at right)
    then the auxilliary fan will only run when the system detects high temp and
    again will automatically switch off after few minutes.
    from that you'll notice if your fan has problems...

    baka wiring lang yan...

    or go to the expert, Mr. Mario 0918-7801507

    we are not againts mr. mario.

    5 times na na may pumupunta samin galing kay mang mario. hinahatulan nya ng sira ang throttle body pero pang bumili na sila or inorder na galing sa kinukuhanan nyang thunder,
    pagsalpak ganun parin.
    and yet taga pangpamga since na malayo sa shop since na sa cainta pa kami. sabi ko tawagan nalang si mang mario kasi nga mas malapit sa kanya at para di na cya lumayo pa. same problem ayaw mag high ang fan puro low lang.

    radiator fan.
    but radiator fan was change recently lang and yes casa yun.
    so uwi nalang yung customer.
    tawag ulit kung may idea pa kami.

    well for those same concern. ayaw may HIGH ng fan pero walang trouble code or DTC.
    check nyo yung takip ng radiator nyo or yung cap ng reservoir.
    dalawang embose yun. pag mayron konting punit or sira cya. well wala ng iba yun.

    yung 2fan nya rad at aircon fan. tes same cila na umaandar ng sabay po.
    try mo walang aircon then tignan mo sabay sila aandar.
    pag naka aircon naman ng hihigh yung rad fan pag mainit na.

    pwede rin yan sa sensor coolant. sa lahat ng sensor nya yun ang pinakamahirap palitan.

    pag yung rad fan eh laging naka on. pag start palang malamang may jumper ang coolant nyan.

    ganito kase yan, as how I've experience sa optra ko.
    kay thunder, meron siyang counter-fit at meron siyang OEM parts pero di lahat meron siya.
    counter-fit is ofcourse a bit low in its price compared to OEM.

    yung throttle body ko sa casa ko binili, at pag OEM once installed dapat areglado yun.
    pagka counter-fit you need pa dalhin sa casa para mai-re-program ng tumama ang
    run ng engine's rpm. otherwise, you'll end up complaining...
    on some issues, yung un-reprogramm throttle comes after few drive test pa. but in my throttle
    i never experience any similar issues as being discussed here.

    tsaka to some, basta important part ng engine, take the genuine GM parts regardless of its
    market price para sigurado ka. (ex. me nabili ako dati kay thunder, yung aking fuel pump set ibinalik
    ko kase maingay, palibhasa counter-fit mura pa, at nung isalpak ko ang OEM, it solve the issues)

    up to you optra owner's... goodluck guys!

    hope you solve your optra problems very soon.

    Default Re: palyado ang hatak after few kilometers

    salamat mga bossing sa replies... ok na yung overheating problem.

    pero parang mas malaki ang problema ngayon...
    pag start mo ok naman lahat, after few kilometers, namamalya na.
    parang kinakapos ng gas ang andar. ang ginagawa ko na lang ay pinapatay ko ulit yung engine.
    pag start ko ulit, ok na sya for few kilometers ulit.

    so far ang nagawa pa lang ay palitan yung fuel filter, pero ganun pa din.
    may naka experience na ba sa inyo nito?
    meron din lumalabas sa dash board na intermittent engine alarm.

    fuel pump na kaya?

    lamang ang fuel pump boss, pero mas maganda na pa diagnose mo muna kung fuel pump talaga ang problem.
    if yun nga i suggest na buy mo yung orig parts kasi maraming angal na sa replacement due to hindi cya accurate at ganun parin yung nagiging problema.
    then pa reset mo para walang trouble code after palitan ng pump. or kung anong man sensor.
