    Reliable ba tong coolant temperature reading from obd port or mas reliable yung gauge?
    ano nga ba ang normal temp ng coolant dito sa atin?

    If I'm not mistaken, it should be above the normal boiling point of water. That is the reason why radiator cap has a pressure rating. If you pressurized the water, the boiling point also increases. The higher the temperature of the jacket water, the higher is the thermal efficiency.

    This is not to say that it should go all the way up and it should perform better. There are material limits and other factors to consider.

    I just don't know why this is not followed for large engines, for example, engines with piston diameter of 900 mm. Usual jacket water temperature is maintained between 80 - 85 degrees Celsius.

    I believe that is within the normal range. However, please take my word with a grain of salt. I'm not an automotive engineer but an ordinary employee who finds time in reading.

    There are guys here who mentioned about PV=mRT with KJ/kg thing, I think they are more competent to give a better answer to your question.

    I'd say go with OEM.

    I'm sure there's a good reason why car makers use plastic on the radiators.
