Do you use radiator coolant?

[ironarch]

I had a discussion the other day with a friend and he said that he does not use coolant in his radiator.

Also he only uses distilled water for the radiator.

He says that using pure water prevents rust or mineral deposits from building up in side the radiator since these are caused by the minerals found in un-pure water (tapwater).

Anybody else try this? Does this work? Doesn't the lack of coolant affect engine temp?

[ghosthunter]

actually pure water makes the engine running cooler as compared to using "anti-boil" additives. Anti-boil additives lower the amount of heat the water can carry.

actually using distilled water is a good preventive... another way is to replace the water in the cooling system every so often so the minerals will not build up over time as you add more water.

Distilled water does prevent mineral deposits since it doesn't have minerals dissolved in it. It also offers better heat transfer then coolant/water combination. But it offers NO rust protection and using it in the long may tend to decrease radiator service life due o rust formation and perforation. Water also has a fixed boiling point at 100 degrees Celsius which upon reaching that temp tend to vaporize and escape through the coolant reservoir route. This would lead to decreased water level level in radiator in turn leading to decreased heat transfer which may ultimately lead to early overheat specially in summer months. The coolant/water combination prevents this water loss by increasing the boiling point above plain water. It also has rust inhibitors that will prevent rust and prolong radiator life. It's somewaht a trade-off but it's there are more avantages on using radiator coolant/water than plain distilled water alone. Remember to use distilled water when also using coolant. Goodluck.

I think some anti-boil additives also have some chemicals added to prevent or slow down the deposits of minerals inside your radiator.

Coolant is important because modern cooling systems have aluminum components that need the lubricating and corrosion inhibiting properties of coolant (usually ethelyne glycol based).

Huwag lang sobra because they tend to 'eat' through gaskets.

[ssaloon]

i agree with otep... minsan i dilute the radiator coolant with water eh.

[OTEP]

Dapat 50/50 or less ang concentration. I prefer 60 (water)/ 40 (coolant).

[mbt]

yup i use coolant in my radiator... and you should too

[otomatic]

I use PrestoneII coolant. Subok ko na pag wala. Kinakalawang ang radiator, lalu na pag hindi everyday driven ang car.






:D

[fundy]

Use Coolant. Roydok said it best. As for the distilled part, I don't really know if it helps. but most coolant have anti rust properties already so using tap water is ok.

[Supierreman]

the coolant actually raises the boiling point of water.

may expereiment sa chem class noon pag nilagyan mo ng asin yung tubig mas matagal sya magboil. Same principle with the coolant. It actuall y raises the boiling point of water above 100 deg C. (pero i'm not saying na lagyan mo asin yung radiator water mo hehe)

aside from that tama sila may anti corrosion properties yung coolant

Gamit ka distilled water kahit yung nabibili sa water refill stations tama yung sabi ni Rodyok... again what we learned in chemistry diba distilled water is a form of pure water walng dissolved substances in it

Tap water may have dissolved calcium salts and minerals kaya possible na may build up in the long run.

[nonie]

I use shell coolant mixed w/ distilled water(30/70 ratio).....but one time ng dalhin ko sa casa dinagdagan ba naman ng tap water ng mekanico....kakainis :evil:

[jesi]

What the heck. I use 100% coolant. My car is nine years old and have 170k miles in it. No problem.

[cj]

jesi,

same here... i use 100% coolant on my 7 year old car and so far soo good! i use glycoshell pala!

[chieffy]

yes, i use engine coolant...distilled water din po gamit ko...1 liter of coolant lang for the whole cooling system....

tama kayo guys:

-pure ethylene glycol boils at 187.2 degrees Celsius
-water boils at 100 degrees Celsius
-ethylene gycol will raise the boiling point of water

-pure ethylene glycol freezes at -13.3 degrees Celsius
-water freezes at 0 degrees Celsius
-ethylene glycol with 50% water solution freezes at much lower freezing points = -36.6 degrees Celsius

[mazdamazda]

tama dapat ang ratio / mixture ng distilled water and coolant.

always check your car's manual if in doubt. ur friend doesn't have the statistics to prove his theory about just using distilled water.

[gulliver]

i use coolant too Glycoshell, and ever since i can remember. pag nag top-off ako, coolant lang via the reservoir. no problems ever since

[recklus]

how can you know the ratio? does anyone know ilang liters meron sa radiator ng ford lynx gsi and kia pride cd5 para alam ko kung ilang liters ng coolant ilalagay ko hehe.

another question, sa radiator may ratio di ba? how about dun sa reserve? naka label kasi sa kotse ko "coolant only" dun sa lalagyan ng reserve.

last question, what are the effects of having pure coolant? do they really eat gaskets? proven na ba to? yung isa ko kasi kotse pure coolant nakalagay, di ko pa nililikot

[OTEP]

Nasa manual yung full capacity ng cooling system.

By cooling system, that includes the reservoir tank.

You should also refill the reservoir with the correct mix. But for topping up and you don't have coolant on hand, ok na ang tubig.

Kung original pa ang coolant ng car mo, hindi pure coolant iyan. The coolant they use from the factory is pre-mixed with water to correct specs.

[hubertq34]

no, im not using any coolant kasi ang alam ko pagmali ang mixture wala din silbi. pagsobra naman nakakasira sa radiator kaya ang ginagamit ko lang ay distilled water, yung tipong wilkins yung nabibili sa 7/11. pagdistilled water kasi hindi nagkakaroon ng corrosion, yung bang nasa mga nasa takore natin.
