Running pure water, will decrease the temp at which the coolant will boil, but not to the point where you should have problems.

Running with the radiator fan in "rekta" mode and without a thermostat, you're wasting a lot of gas... the car will be taking a whole lot longer to get to operating temperatures... which is bad for economy.

The metal shavings suggests that you might have a water pump problem, which is causing the high temperatures. Should also replace the hoses. Old hoses can expand, which decreases the pressure of the cooling system... which can lead to premature boiling of the coolant.

Given you've got shavings in t
Sir bitin ata yung message mo.

Again sir, I've done my homework kaya nga po sabi ko unti unti ko restore yung cooling system. I already know what you have said and thanks for re-confirming.

My only question is that based sa mga nabasang details ng cooling system ko, should I be using 0.9 cap or 1.1 cap? I just want to confirm if I can use 1.1 kahit overhauled at matanda/weak na yun radiator at lumolubo yung radiator hoses ko.

But I think you've kinda answered my question when you mentioned hoses expand that leads to premature boiling. I think 1.1 cap gives more pressure sa system na pwedeng ikaputok ng hoses as I've read na use high pressure cap if there's no weak points in the system. Tama po ba?

Currently I'm back to 0.9 cap federal mogul brand..

My question is purely educational purpose po. For the record I'm self-learning car mechanics, DIY guy as a hobby and used 4g15 carb engine to learn. I'm slowly returning everything sa stock factors po.
