    lower boiling point - coolant
    rust protection- coolant

    distilled is only for temporary use.

    Water dissipates heat better. Coolant(glycol based) is mixed to raise the solution's boiling point, raise water's PH, push corrosion back....& those in temperate regions, this will serve as anti-freeze.
    Periodic coolant swaps are required as it will degrade & turn acidic over time. Check the PH level of coolant annually. It should be maintained between 9.5-10. If it goes below 8, swap ASAP. Your engine, water pump, radiator, heater core will thank you for it.
    For those who are going for a complete engine overhaul, take this opportunity to go Evans Waterless Coolant & stop worrying about periodic coolant swaps. Evans CANNOT be mixed w/ water. System should ideally be free of water upon switching.

    Litmus test? Where to avail?
    Actually, 3 - 4 years ako mag flushing. Or is that too long already?

    The reason is...

    My odo is 102,304

    Like what I said before, partly my negligence. Two years ago, my car almost overheated. Radiator was then converted to brass tank. That was the time I did not bother to add proper coolant. Just distilled water.

    Then by January 2018, radiator started leaking again. Most probably dahil na sa water pump. Naubos na impeller. Causing high heat and pressure. That’s why I bought a cheap obd scanner/reader sa lazada to monitor my coolant temp. And I was bit surprised mataas talaga readings. Ranging from 98 to 110c city driving.

    Changing the thermostat and radiator cap did not solve my problem. Only when they checked my water pump... and the impeller was gone.

    Timing chain yung engine ko. The water pump can easily be replaced.





    Maybe with proper coolant and religious flushing of the cooling system, di pa masisira ang water pump at 100k odo.

    I even bought a surplus fan clutch. Thinking it was my fan clutch. But it was not.

    I suggest, when your car is already old, check the water pump first. I tested my thermostat and it’s still working. Kahit sobrang rusty na tingnan. It’s still functional. Di pa pala kelangan palitan.

    But no regrets replacing everything.

    Thanks...wow fairly not that high mileage pala. I've seen much worse corrosion issue where the water channel is literally with thick lined brownish corrosion byproducts on them. Your's seem still in good shape yet the impellers were eaten out. It seems in our cooling system the impeller pala pinaka weaker metals/materials on them. Maybe due to it's spinning motion, Erosion and corrosion literally will eat the metal away.

    cavitation pa. aside from corrosion protection the additives in the coolant also provides some cavitation protection.

    Imagine it can go unnoticed. Naawa ako sa ride ko. Most probably mga ilang months wala na pala siyang impeller. Nagkataon city driving lang ako this year. Last long distance ko Nov 2017 pa. Di naman nag overheat.

    My temp gauge starts to move past halfway at 115c. Nilalagnat na pala yung engine ko di lang namalayan kasi kahit 110c “normal” pa siya sa range.

    Buti nalang walang damage sa head gasket. Ngayon sobrang okay na ng temps. 88c kahit hapon at stuck sa traffic. ✔️✔️✔️

    By the way, my radiator is also new.

    Replacement only. Not oem. [emoji16]

    And yes plastic tank.

    Car: Sorento 2009 2.5 EX VGT

    Should I be worried? Coolant is 50/50 mix. I checked other vehicles they stay at 88c-92c.
    anong obd reader ang binili niyo bro sa lazada?
