If you notice ang level ng full ng reserviour ay almost kalahati lang ng tank so that it will compensate the overflowing water from the radiator. Kung nasobra lagay mo matatapon talaga yon.
Kung patay na makina mo, babalik uli yong sobrang tubig from the reservior to radiator because mas mauunang mag cool down ang H2O at the radiator because of its cooling fins.

Pag binuksan mo ang radiator cap ng mainit pa 'to at pressurized it will boil * atmospheric pressure kaya matatapon yong tubig mo sa radiator.

That's explain why dumadami tubig sa reservior and loosing water fr radiator if you open its cap when hot.

Mga Gurus correct me po if i'm wrong.

But it is very possible na clog na ang fins ng radiator mo.
My radiator cap wasnt been replace since 10 yrs na ito.. flushed last 4 months.. 50% water and 50% coolant wasnt replace for 3-4 months until now.. my water reservior will not overflow if the engine is cool or not running like in the morning.. but if the engine is hot it overflows and it looses 1/4 of the water of my radiator.. ganyan po napansin ko..

what do you think po? any suggestions po? flush naba ?

what po mga suggestion ninyo mga sir?
