radiator maintenance

[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.

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?

*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. =)

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.

Sir,

yon po ibang nabibili na mineral water may marka na "distilled water" okay ba yon para sa radiator?

Ideally, you should be using distilled drinking water.

The reason for using it is you are avoiding the minerals found in tap water/mineral water, which can form deposits in the cooling system.

But a little tap water for top ups isn't that bad.

Sirs,

Napansin ko na nababawasan yung tubig sa reservoir. Typically, kailangan ko shang dagdagan weekly. AFAIK di ba di dapat nababawasan yun? Ano po kaya problema? Could it be the radiator cap, kaya tuloy nag e-evaporate yung coolant sa radiator and na si-siphon yung laman ng reservoir?

[OTEP]

The rad cap is a good place to start. They're inexpensive and easy to replace.

I agree with changing the radiator cap. Also look for leaks or loose hoses.

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.
