radiator maintenance

[howel14]

mga sir gud pm!
ask ko lang po kung ano ba ang proper maintenance ng radiator? every ilang months po ba cya dapat nililinis? ok po ba gumamit ng coolant compared sa ordinary na water? please advise, thanks

[Bogeyman]

Ah, dapat talaga coolant ang ginagamit. Using ordinary water will corrode your radiator.

as much as possible, drain your radiator at least once a year, but if you can afford it, at least, every six months. yun nga lang medyo magastos sa coolant, pero its all worth it.

pwedeng i-DIY yan. just look for the drain faucet at the bottom of your radiator, drain everything (make sure that the engine is off), and mix a 1:1 coolant-water mixture, close the drain faucet, put the mixtureinside the radiator, and start the engine. check mo maigi kung walang tagas and yung response nung temperature ng oto.

it is recommended that you use a coolant mixed on the ratio stated above. why? aside from protecting your radiator from corrosion, it boils at a higher temperature, making your engine more protected from the heat.

recommended brands? maski ako.. but i personally use yung Shell brand.

we have a 5 and 2 year old car prior to that some 3 and 4year old car.


I never used Coolants just some distilled water or sometimes even just MAYNILAD water. I never had problems with all those car concerning radiator. I just change them almost twice or even up to 4 times a year. (We had a car 4 years hinid napalitan ang tubig, nagputik na yata sa kalawang heheheresulting to overheat)

I believe the trick is in the frequent flushing. Not on some additives or even at the coolant

I think its true that coolant has a higher boiling point but i think the corrosion or rust is still there. The color of the coolant just hides it.

e anyway?

thanks sa mga inputs mga sir very informative!

gusto ko lang po itanong... every week ko po pinpalitan ng water yung reserve tank ng radiator... meron po kasing color brown or putik na residue dun. never naman ako naka encounter ng overheat ano po kaya yun? btw, i only used distilled water and no coolant. tnx

baka sa dumi lang ng tubig yan that settles.

i doubt if that could be from the water considering he drains it every week and he uses distilled water.

that can be the lining of the radiator.

[Galactus]

Nakow, kulay putik. That means naghahalo na yung oil at tubig. Pa-check mo na yung cylinder headgasket mo, sure ako may tama na yan.

[MAXBUWAYA]

Thats rust. kung may solid particles

Ganyan dina sa akin weekly may "Skidmarks" yung reserve ko

[rogie]

*Galactus, kung oil yun dapat di magmix sa water, tama po ba? saka wala pa naman po white smoke coming from my exhaust. yung residue nya dry color brown... duda ko nga parang latak ng tubig. will take picture para makita nyo. tnx

[userfriendly]

Try flushing both your radiator and reserve tank and see what happens. Baka madumi radiator mo. I suspect that the brown residue is some sort of scale formation from boiling water.

[Galactus]

I've experienced oil and water mixing in my radiator, dun sa Galant Sigma ko. Used engine oil and water do mix, have it circulate in the engine, pick up contaminants along the way, and add heat to the equation. Kulay Milo siya. Brought it over sa mechanic and his verdict was a warped cylinder headgasket.

[OTEP]

And whats with these Hardware malls selling Preston Anti Freeze

Anti-Freeze is just another variant of coolant, it also has the lubricants and other properties essential for the aluminum components of the system.

[Galactus]

Yung mga anti-freeze na yan eh, galing US/North America. In certain states, esp. Alaska, the weather gets so cold that the water in the radiator freezes solid, kaya may anti-freeze.

Dito naman sa atin, tropical ang klima, kaya di na kailangan. Pero AFAIK, component lang naman ang anti-freeze sa coolant. Hindi naman yata sya sold separately.

[4JGtootsie]

I think sir OTEP is correct antifreeze and coolant additive are the same. Increases boiling point and decreases freezing point. Coolant in engines is the water, oil can also function as coolant as well as lubrication.

Sir Galactus,
Warped cylinder head? CH gasket?

[rogie]

*Galactus, sorry di ko nakunan ng pics umulan kasi last night. when im looking on the water sa reservoir clear naman sya. yun color brown residue nandun sa hose (eto yung nasa loob) and latak on the water. =)

Hi All!

For the health of your radiators, cooling systems, and engine in general, use a 50% coolant and 50% distilled water mix.

Most vehicles require that you use coolants that contain ethelyne glycol.

Coolants / anti-freeze help increase the boiling point of the distilled water (for tropical / hot weather mix) to improve the cooling of your engine.

Plus, as OTEP said, they contain other chemicals needed to maintain your cooling system.

You must use distilled water because the mineral content found in hard water (tap water) and mineral water will eventually cause corrosion in the system.

Distilled water practically have no minerals in them so it will not cause corrosion.

Hope this helps.

Best thing to do to keep your radiator functioning efficiently is to make sure your radiator caps are in good condition. Radiator caps contain a spring that activate around 15psi to release excess pressure. In optimum condition, this rarely happens, and your radiator is kept tightly sealed, meaning your coolant does not evaporate. Adding (ethylene glycol (EG) or Propylene Glycol (PG) ) antifreeze, raises the boiling temperature of the coolant to 255 Deg F or about 124 Deg C. Water evaporates at 100 Deg C. Keep ratio of antifreeze to water at 1:1 or maximum or 3:2. Too much antifreeze reduces the coolants heat carrying capacity.

Don't use tap water! or mineral water..These contain minerals that will build up as rust and scale. Distilled or demineralized water is best.

Lastly make sure you have your cooling system is tightly sealed, and check level of coolant consistently.
