Ganito kasi nangyari, i consult ko na din dito.

Two months ago, nagpalit ako ng radiator (Hyundai Getz 1.1, 07 Model), dahil sa overheat. Everything was checked from the water pump, to the thermostat to the radiator fans so the cause of overheat was determined to be na nasa radiator nga.

So far, nawala ang overheating concerns. Kaya lang napapasin ko na yung radiator losses significant amount of coolant wherein kailangan ko mag top up ng around 1/4 liter every week.

Tried looking for leaks, wala naman. Tried checking kung may nagmimix na coolant sa oil, wala naman. Wala ring smoke.
Walang kulo yung reservoir and hindi nababawasan yung coolant sa reservoir.
Nagpalit na din ako ng radiator cap two weeks ago.

Ano kaya reason neto? Is this normal? I don't think so dahil dun sa luma kong radiator and dun sa other cars ko, i seldom top up. Saan napupunta yung coolant?

Wala naman akong issue, kaya lang, dito sa oto kong ito, eto yung parati kong chinecheck ang radiator coolant level.
