Radiator Reservoir overflow just now ...

[Dezaremos]

Ibig mo bang sabihin, in two parts na yung rad cap? Palitan mo na kaagad. Hindi ka pa naman ba umaabot sa punto na natuyuan ng coolant at nagoverheat? If this is the case, it might be a leak in the head gasket.

yes sir, in 2 parts na yung rad cap ... hindi nman ako natuyuan ng coolant .. sa isang buwan, hindi nman nababawasan ang tubig sa radiator .. sa reservoir may konting bawas sa in a month .. kahit nga long hours of drive, intact pa rin yung coolant ..

kagabi na lng nangyari na ng backflow yung reservoir after ko ni revv up to the redline within a few seconds of starting the engine at hindi ba nka engage yung radiator fan ...

in my opinion, your story is... incomplete... needs further trouble-shooting.
in the meantime, i recommend replacement of that radiator cap, and further observation while in use.

Feeling ko may pressure coming from the cylinder head. Kaya kahit malamig pa engine nag build up na pressure sa cooling system. Happened to my FM before.

But same with dr. D, kulang yung story. Whats the condition of the engine?

Tama si Dr. D at Crazy_Boy, a little more details will help to diagnose the problem. Pero hindi dapat magtapon from the reservoir. Unless pinuno mo ng husto nung nagtop off ka. Palitan mo muna rad cap then top off the coolant (proper fill lang) and then monitor. If you can securely place a catch bottle doon sa relief line then it will help gauge the amount being expelled. Monitor closely kasi if it's a case of head gasket leak, mahirap matuyuan, baka magwarp head mo then more trouble leading to top overhaul.

I decided to start my corolla GLi and less than a minute after start, I rev the engine over & over for a few seconds then idle .. I then rev it to the red line for a few seconds and again ..

Nung lumabas na ako sa kotse ko at tinignan ko yung muffler ko, napansin ko may tulo ng tubig sa cemento, sinundan ko kung saan nang galing, na trace ko na sa ilalim ng engine bay .. binuksan ko yung hood, nakita ko lumalabas yung tubig sa reservoir ... hindi naman nangyari sa akin ito kahit long drive ..
Ano kaya cause neto ?? dahil ba hindi pa ng open yung thermostat at ni revv ko ng ni revv at hindi maka circulate yung coolant kaya ng overflow sa reservoir ?? Galing din akong 2hr long drive pero naka park na yung kotse ko ng almost 3hrs ..

May possibility ba ng engine damage ???

Halos pareho yan ng problem nung Corolla GLI din ng friend ko.
Pa-check mo bro yung radiator mo may barado na kaya tumaas ang pressure, kaya bumubulwak sa overflow reservoir, yun ang naging problem at naayos naman matapos linisin yung radiator.

Pacheck mo sir sa mga shop para makasigurado libre lang naman check up

Is your coolant rusty, oily, or worst case, 'chunky'? If not, just replace the radiator cap for now with the same rating and observe. From the way you described the cap, it's up for replacement anyway.

Change first your radiator cap (always get original or Denso) but there may be a cause for the pressure as aforementioned so have your engine compression tested.

check ko kanina before ng cold start, tinanggal ko radiator at reservoir caps tpos start ko ng engine .. wala nman bubbles at backpressure at ok nman ang rpm ng engine .. drive ko kanina for 30mins, ok rin ang takbo at hatak .. so wlang leak sa cylinder head ...
