Radiator losing water but reservoir still the same level

[mark_celiz09]

Hello,

Ask ko lang, anung possibleng reason kung bakit ung radiator ko nagbabawas ng tubig pero ung reservoir hindi. Di ba dapat kapag nagbawas ung radiator, kukuha siya dun sa reservoir to compensate ung lost dun sa radiator? may connection ba to sa radiator cap? Kapag binuksan ko ung radiator cap parang may pressure na lalabas.

May mali ba sa napansin ko?

[Langabe]

Check niyo muna yun radiator cap baka sira na yun gasket.

[1D4LV]

yup, check mo muna or replace the rad cap.
kung ganun pa din, there is a leak somewhere....

The rubber seals of the radiator cap is not sealing properly because it has hardened or crack from age and heat. Replace it.

And if you change your radiator cap, go for OEM or a known brand like Denso. Don't go for the cheap ones (i.e. Circuit).

bili ka sa surplusan kaysa sa lokal na nabibili sa mga auto supply.. may makukuha ka orig na surplus..pili kana lang..150 lang kuha ko..

Bago naman ung rad cap ko un nga lang di ko alam kung masyado bang matigas ung spring niya kaya di maiaangat para pumasok ung tubig galling reservoir. Dapat ba matigas ung spring o hindi?

Ganito din nangyari sa oto ko, my leaked cylinder head gasket kaya top overhaul ginawa.

Supposing you have no leaks or breaks in your cylinder head gasket, any water that goes into you reservoir should in theory be drawn back into your radiator.

posible ba mag-evaporate palabas ng reservoir ung coolant?

[EVO-V]

Yes, but the coolant component will not evaporate until 179C. So what happens is that the radiator could be clogged, and it will build up pressure and push the coolant through the overflow pipe into the reservoir.

If the pressure is excessive, the reservoir fills up, a pressure cap somewhere pops, and then pushes out the coolant out of the reservoir but doesn't draw anything back in. That can explain the loss in the radiator while having a full reservoir.

Bought a surplus rad cap for 120 pesos. So far, ung dating takbo ko ng mga 10 to 15km na may nababawas na tubig sa rad agad ngayon parang ala na. Puno pa rin nung last na nacheck ko. Tumakbo ako ng mga 50km last saturday, and mukang ok pa din siya. Sana un na makaresolve ng problema ko sa waterloss. Just sharing.

Likely when you opened your cap, you let out air, and then resealed your system.

The radiator overflow is normally the highest point in the loop and it will let air out first and then draw back coolant from the reservoir to replace the volume lost.

Habol sa tanung ng nauna nating ka tsikoteer..bro hindi ba tumataas temperature mo nung nag babawas kamu ng tubig ang radiator mo?

Nope, di naman tumataas kasi di naman sobra ung bawas sa radiator ko. mga isang basong tubig lang.

If that solved your problem, then buy a brand new OEM radiator cap.

I think I'm good with the surplus already.

[EVO-V]

A new cap is only P150 or so. I don't get it why you had to buy a surplus cap.

[mark_celiz09]

Because the cap I replaced has been just recently replaced. Circuit brand. But I notice that it is not getting water from the reservoir that's why I bought a surplus. I think I can't get a OEM or Denso cap for 150.

[EVO-V]

The Circuit brand is a rebranded piece of junk from China.

There's a chance the sealing wasn't properly engaged.
