radiator: 100% water vs coolant

[badkuk]

i recently had my aux fan replaced, and have been going on test runs. this afternoon pansin ko that the temperature went slightly above the median(although malayo pa naman sa overheat). afaik, except for the overheating episodes this month, it rarely reached that temperature.

working naman ung aux and radiator fan upon checking. about the only thing i can think of is that fact that i refilled my radiator with tap water. yun kaya ang problema?

Coolant has a higher boiling point, hence, it's better than water.

[alwayz_yummy]

baka naman barado naman ang radiator mo? naoverhaul na ba(general overhaul--> top and bottom ends were removed) fush your system w/ radiator flush, the run the engine para maalis din ang mga naipong tubig sa block at naiwang radiator flush(cause of micro holes sa radiator if left inside....

never use coolant in its 100%..haluan mo ng distilled water(para di na mag-scaling), kahit 500-1000ml man lang...

When you open the cooling system it becomes depressurize hence it looses its ability to endure higher temperature.Once it becomes pressurized again temperature becomes stable.

Another reason maybe you filled your cooling system with water while the thermostat is closed making the system partially filled.

Using distilled water is good for the cooling system because its less prone to evaporation and cleaner then tap water.

tap water is mineral water. meaning using this kind of water in automotive cooling system is not a good idea since mineral deposits in the form of rust will be generated, resulting to corrosion..

Like mentioned, ethylene glycol (antifreeze/coolant) has a higher boiling point. Get the correct one for your car not the green generic types, they won't have the stuff you need like corrosion inhibitors, etc.

You also might need to burp your cooling system, baka may air pockets. Find the highest point on your cooling system and see if you have a bolt you can loosen so that you can let the air out through it and effectively burp your car's cooling system that way.

Avoid tap water, it will have mineral content which will create deposits in the long run. You will need to use a citric acid flush after a while if you keep running like that.

hmm...this may explain why i only got about 3 pails full when i drained it; according to the owner's manual, it's supposed to be something like 5-6 liters.

pardon the kulit, pero pano po maensure na nakabukas ung thermostat? temperature activated siya dapat di ba?

hmm...is this the same distilled water you put in car batteries?

hindi naman po sa namimilosopo...pero pwede rin kaya ung purified water sa water refilling stations? afaik most of the impurities have been filtered out anyways...

remove the thermostat, dop it into boiling water. ifit opens fully ok pa. if it doesn't move then hindi na.

[XTO]

distilled water for battery is okay, mas sigurado lang kasi yung distilled
pure drinking water like absolute and wilkins dahil pwede nga inumin.

anti-rust lang gamit ko na coolant kahit na hindi anti-freeze.

tsaka talagang maiinit ngayon kaya doubled ang hirap ng radiator.

Question lang po... Lagi po nag babawas ng water... although I use my car for short trip lang kaya lang baka maubusan ng tubig pag long drive na... Radiator po wala namang leak Water pump Bago po... Yung mga fan umaandar naman po ng maayos. Ano po kaya Problem?

check your radiator cap and hoses.

run your engine w/o the radiator cap till working temp. (1/3-almost 1/2). at idle, tumataas ba ang tubig? if so, have the thermostat checked, baka di na nag-oopen ng maayos yan.

if the water in your radiator spurts out violently(like what happened sa liteace ko) have your cylinder head resurfaced, valve reseating and re-lapping and cylinder head gasket replace(in short, have a top-overhaul)..

kung *idle slowly parin ang pagakyat ng tubig despite na napalitan/ni-remove mo ang thermostat, its a sign na either weak ang waterpump mo/may bara sa system at di makacirculate ng maayos/ sign na premature/humihingi na ng top-overhaul..

na-overheat mo na ba nga pala ride mo? its one of the causes kaya isipin mo mabuti..

basta ko, mga MAY, total flush na ako sa cooling palit na ako sa usual mix ko -> 80/20 coolant/water mix (liteace ko: 6liters=4.5liters coolant+1.5liter manila pure d.water)

[speedyfix]

have it inspected to see where and what is the cause ng pagbabawas ng tubig...

80:20 coolant/water? what coolant brand ginagamit mo? parang ang taas kasi coolant parts?

[speedyfix]

o.t. clutch replacement interval depends on the use.

back to water s coolant...

[boy astig]

Sir, how often do you change your clutch? Mileage po?

+-75,000 kms. Usually I do 3 long trips a year (manila-isablea-tugegarao). If I do more than this, I have the clutch and water replaced on the 3rd year.
