out of curiosity --question on coolant reservoir

[dnomyar]

Dear fellow tsikoteers, 'am just wondering what's the purpose of the coolant reservoir attached to the radiator? is it a holding container in case coolant overflows from the radiator? or it in case of overheating, the radiator sucks in the reserve coolant from the reservoir? can anyone enlighten me on this? add ko na rin, is it ok to top up pure coolant in case the level in the reservoir goes down? or it should be diluted with distilled water? Pardon for my ignorance, i've been longing to ask this. TIA

Reservoir..meaning reserve.. so its use is to reserve so that the radiator wont have a problem.
and on the coolant..ala akong alam :P try to read the instruction in your coolant bottle

[meledson]

kadalasan pag umiinit nag e-expand. imbes na matapon ang coolant pag nag expand dahil sa init (normal) ay maiipon sa reserba. kaya ang max limit ng reserba ay hindi sagad.

pag lamig naman, mag contract, kaya hihigupin ang coolant pabalik sa radiator.

salamat sa replies, natanong ko kasi ng sobrang trapik dahil sa rally ng IN
C mejo mataas reading ng temperature more than half sa gauge. then pagkaumaga mejo bawas yung reservoir kaya nagdagdag ako purong coolant hanggang sa kalahati (full level). eh naisip ko baka di dapat puro nilagay ko kundi hinaluan ko distilled water. so far balik na naman reading temperature gauge sa 1/4. napansin ko lang mas mainit hood ko kesa nung nakaraan although same distance and traffic condition. baka napraning lang ako. salamat po uli.

a 100% working cooling system with no leaks and no problems will never need a top up of coolant or water on the reservoir... its a closed loop system, the same amount that's sent to the reservoir will also be the same amount to be sucked in back to the radiator.

if you topped it up, then the coolant or water which was lost during that traffic must have escaped through something...
try to observe if it will happen again.. but just to be sure check the coolant lines and hoses, and check the engine for any signs of coolant marks..

It is not a sealed system, some water do evaporate. pero konti lang. After more than 1 1/2 years, I have to add coolant sa reserba. umabot na sa minimum. Pero puno pa rin sa radiator.

thanks for the inputs, so it is reassuring that topping up with pure coolant is okay. I see that there is no problem with my radiator as the water level is up to the brim, and the color of the coolant in the reservoir never changes. I'd be alarmed if the color turns to rainbow shade, a sign that oil is seeping in the cooling system.

pwede din top up lang ng distilled water absolut o wilkins . since nageevaporate naman yun water di yun coolant

Yup, not 100% sealed. meron talaga mist lalo na sa may cap ng reservoir paminsan-minsan. But matagal nga abgo ka kelangan magdagdag.

[miko101130]

i did not say 100% sealed... its 100% closed loop system... ibig sabihin self regulating unless buksan o tumagas..

[yapoy86]

hindi po closed loop yan kasi may radiator cap ka na may spring valve.... yung reserve hindi dapat nadadagdagan ng tubig.. in time mauubos yan kaya kailangan mo mag top-up... yung radiator nag vent din yan ng steam kaya hindi dapat pinupuno yung reserve kasi doon dadaan yung steam.. pag vent nyan ng steam, suck naman nya yung cool water from the reservoir... kaya may vent din yung reservoir sa ibabaw for the steam

[Ry_Tower]

ok na ito. Puwede na i-close. Baka saan pa mapunta.

*yapoy86: Kung hindi closed loop cooling system ang tawag dyan eh ano pala ang tawag sa cooling system na meron tayo sa kotse?

A coolant concentrate should be diluted with distilled water.

Well done!....

medyo nalilito lang ako dun sa sinabi nyo na yun reservoir di dapat nadadagdagan ng tubig. ang ibig bang sabihin pure coolant lang ang ilalagay o pag

[dnomyar]

sorry, naputol tanong....ang kasunod "o paghigop ng radiator ng coolant sa reservoir ang binabalik nya ay coolant din at walang tubig? sensya na po, gusto lang maliwanagan. salamat po ng marami.

very well said bro.

Coolant in the radiator should be the same proportions as the coolant in the reservoir. Check your user manual regarding coolant types & mixture. Most manufacturers recommend 50:50 mix coolant:demineralized water, some 30:70.. Too much coolant may harm your engine internals.

There are also 2 types of coolant EG & PG.. PG is more environ-friendly but wrong proportions and incorrect duty cycles could result to harmful acids in your engine. Some rust inhibitors in the coolant may also destroy your engine seals and rubbers..
