Radiators

[jaypee10]

mas ok parin sa radiator ung all copper,sa aluminum kasi lighten siya .pero para sa akin mas ok ang copper madaling i overhaul or buksan.madaling tapalan ng tingga sakali mang mabutas.at once na ipalinis mo ito pag balik parang bago na ulit.kaysa sa mga plastic top na kadalasang nakakabit sa mga bagong sasakyan ngayon,pag dating nung time na magbara na siya at kailangan buksan.pag balik minsan nagkakaroon na siya ng singaw.kasi nga hindi na factory seal ito .isa pa katagalan ng plastic nagkakaroon ng crack or pumuputok ito.

Also di din kailagan magpaka OC sa pag flush ng tubig sa radiator kung wala naman issue in the first place. If you read your manual most coolant lasts for 5 years or 60,000kms as long as tamang coolant ang ginamit mo. Sayang lang effort mo sa frequent palit ng tubig pero mali naman paraan mo.

Nabasa ko lang somewhere... Kakainin ng pure distilled water lang yung linings ng radiator sa katagalan.. Forgot ko na kung anong tawag sa type ng corrosion na yun, since water is a solvent unti unti niyang i di disolve yung linings sa loob ng radiator and other surfaces. By adding coolant nababawasan yung effect ng pag corrode ng internals. Meron pa nga sacrificial metal bar na maliit na naka lagay sa radiator cap para siya yung unang kainin ng corrosion at hindi yung lining.

If water is a solvent, then I nor we should not be drinking water since we are born in this world.

Pabasa na lang sir.. Ibang "Solvent" ata yang nasa isip nyo.

Our kidneys and water make a great pair

Our own kidneys and water's solvent properties make a great pair in keeping us alive and healthy. The kidneys are responsible for filtering out substances that enter our bodies from the foods and drinks we consume. But, the kidneys have got to get rid of these substances after they accumulate them. That is where water helps out; being such a great solvent, water washing through the kidneys dissolves these substances and sends them on the way out of our bodies.

Based on my own experienced, on two previous brand new vehicles that we had owned( both different car manufacturers). Radiator coolant from casas, never will last up to three years. If you intend to retain it for two years or so, in your radiator cooling system, expect to encounter what I had experience, a clogged in an engine cooling system. Even if the manuals says, 60k km is the replacement period. Replace or replenish your coolant every 1 or 1-1/2 year, if radiator coolant you prefer to use in your engine cooling system.

You mention here that water is a solvent, not me. That's is why I questioned YOU, if water is like that, never we, people be drinking it, since our birth.

Yes, you SHOULD replace coolant at regular intervals. Because the corrosion and scale inhibitors do not last forever.

But those inhibitors DO protect your cooling system from the effects of water, which are more pronounced if you use pure water.

We breathe corrosive gases (oxygen) every day. We drink and eat (fruit/meat/vegetable) acids that would rot your teeth if you didn't have saliva. To ask why we drink a solvent simply shows a misunderstanding of body chemistry.

Water is a universal solvent. It leaches minerals and will eventually eat its way through an iron block or an aluminum radiator. Older copper radiators took longer to corrode, but only because they used thicker tube walls... which won't fly in today's cars, which rely on the better cooling afforded by thin-walled aluminum radiators.

Even worse, pure distilled water will boil more easily, and without the protective coating of coolant, you can get cavitation bubbles with pure water that will eat through the water pump impeller or the water jackets lining the cylinder walls... in some cases, on modern diesels, this can happen in just a few hundred hours. And these effects will happen whether you change the water regularly or not. To tell someone with a newer car than you to use pure water is dangerously reckless.

-

Pure water isn't the answer. If you want to run nearly pure water, you need an additive such as Redline Water Wetter to forestall cavitation effects inside the engine and to prevent corrosion. Best of both worlds. You get the higher heat capacity of water, while still having the protection of coolant.

Tanong ko lang mga sir. ung tubig ba sa labas kapag umuulan e pwedeng pumasok sa loob ng radiator? pati mga putik?

No otherwise your radiator have overheated already. The putik I think are oil sludge and gunk.

Nope... malabo yan mangyari kahit may butas pa radiator mo because of the heat and pressure palabas ang direction ng laman nyan

Mine is more than a decade old. Is it advisable to replace or repair radiators? What maintenance is required if its still dont have visible leaks, Are there antirust additives that will do? TIA

If you have maintained the factory anti-freeze coolant quantity and quality that is usually green and containing ethylene glycol then you should not need to do anything. If you have engine temps that appear to be climbing the very first suspect on a 10 year old vehicle is the engine thermostat. If you have an electric cooling fan vs. a belt driven cooling fan the thermal switch in the radiator may not be turning the cooling fan on. That would cause the car to be hot in stop and go traffic but run pretty much at normal temps on the open road.

Bakit most of the cars I've encountered (not mine though) nagkakaroon ng deposits sa ilalim ng radiator kahit coolant ang ginagamit nila?

[StockEngine]

Aluminum corrosion. Needs proper flushing and correct interval.

Has anybody tried to DIY flushing the radiator water? Pinagawa ko kasi yung radiator ko kasi nagkaroon ng leak sa gilid. But then yung tubig na nilagay is tap water (wala kasi akong coolant that time). Balak ko sanang iflush lahat ng nilagay nila, then add coolant.

Questions are: is it better to use Prestone Concentrate with water in a 50/50 ratio, or a Prestone ready to use na walang water na ihahalo?

2nd is, kung ano man ang sagot sa itaas, ilang liters ba ang kailangan na ilagay sa radiator and sa reserve?

1. Either inadequate or too much coolant to water ratio - Best to use pre-mixed jugs to alleviate any mixing errors.
2. Wrong coolant type - Some vehicles will develop leaks at the pump if the coolant is not compatible with the pump seals
3. Using ordinary water (distilled or tap) to top up - Lower boiling point and zero corrosion inhibitors
4. Using the radiator to ground accessories - Will cause electrolysis and promotes corrosion to occur (the corrosion inhibitors will probably be used up by the time you change the coolant)

The engine block and radiator components are one big electrolysis machine, and throughout the life of the vehicle, differential voltages exists between them which causes electrolysis to occur. The voltage can be from static generated by the pump, or ground differential between the engine block ground and the radiator ground. For that matter, even if the cooling system is sealed from oxygen and you put in pure/100% water, a chemical reaction would still occur.

To prevent this, a lot more chemicals are added into a coolant other than ethylene glycol. Equally important as the coolant's heat transfer capability is the corrosion inhibitors. These chemicals serve as sacrificial lambs to significantly slow down the corrosive tendency of the cooling system. So if you did any of the four I mentioned above, you risk causing an imbalance in the chemistry which will usually negate the protective properties of the coolant or even accelerate the corrosion.

DIY radiator flushing, madami tutorial videos sa YouTube. Search mo lang.

Use Premix 50/50 coolant. Ready to use. Makes life simpler.

Iba-iba capacity ng radiator at reserve tank. Magready ka ng 8 liters para safe. If sobra, pwede mo naman gamitin later.

tanong lang how replacement radiators compare to surplus OEM and brand new OEM.

If for example in a 21 year old car nasira na ang radiator, and unlikely na meron pang bagong OEM. Which would be a better choice, The surplus OEM good condition thats also almost 20+ years old or the replacement made in china/taiwan na brand new?

would the brand new replacement last longer than the surplus OEM because its newer? or mas matibay pa rin talaga ang original na good condition

Mostly new CASA OEM parts if not made in China, Taiwan, India, Malaysia or Thaiand, are screen thoroughly from their QA Control. And are mostly expensive sold by the CASA than a replacement OEM one, sold in aftermarket supply store.
