Do you use radiator coolant?

[Jigga]

Yes, you should. Coolant is not only for the radiator, it is also for the rest of the cooling system which involves the water pump, etc.

I mix coolant with distilled drinking water. Check the specific coolant you will be using for the correct mix (unless it's pre-mixed).

You need to drain the whole cooling system. That includes water within the water jackets and other areas. Your mechanic should know how to do this.

Intervals vary with vehicle. Check your owner's manual.

Otep,

Here's the problem..

I bought the car 2nd hand.. walang kasamang owner's manual..

One other thing... Ung radiator na nkalagay sa auto ko is for cars na matic...

What should I do?

I assume your car is manual. I think that it should be ok. Afaik AT cars have bigger radiators compared to manual. Someone pls correct me if I'm wrong.

Just use a 50/50 mix of distilled water and coolant or just buy the premixed stuff. Replace every 2 years.

[OTEP]

In most cases the radiator for the A/T variant is of the same type or is more robust/high cap than the M/T's. So, as previously posted, it's ok.

[Galactus]

Radiators for A/Ts are similar in size to M/Ts, pero may AT cooler line for the transmission

Medyo pricey din ung prices ng mga coolant eh..

Some say it should be replaced every 2 months to 6months because the weather here sa Pinas is mainit..

Baka daw pumanget ung rad..

What do u suggest na magandang brand, ung ok and medyo nde pricey...

[OTEP]

Every 2 months? Baka naman ahente na ng coolant ang nagsabi sa iyo niyan. :lol:

Ako nga I just use 2 liters Whiz concentrated (Php180/liter). Tapos every 2 years ko lang napapalitan (around 30-40,000kms).

Hahaha!!!:D

Cge, do that..

It's not that hard. But coolant should be properly disposed of [not flushed down the drain] kaya madalas sa gas station ko na lang pinapagawa. Kasi sabi ni chieffy dati, may mga iniimplement silang policies regarding waste disposal sa mga gas stations.

Ethelyne glycol tastes good but is very poisonous kaya tepok agad ang mga stray animals na makakainiom nito.

Tastes like Kool Aid daw.

The Inuits (formerly known as the Eskimos) are notorious for drinking that stuff that's why they have an increased rate of liver cirrhosis and liver failure.

Polar bears love that stuff too....

guys how do you drain your radiator? yung iba kasi advise sakin the engine should be running while draining para pati daw yung water sa mga hose matanggal din. is this true? and do you use radiator flush?

[OTEP]

No flush for me. There is a drain plug on the radiator and on the engine block itself which allows you to drain all the fluid in the cooling system.

It's the block drainage most mechanics forget. Actually, I can't find the one for the 4d56. Hehehe. On the Benz, it's pretty easy to spot.

[morpheus08]

Car noob here so be gentle Upon draining the radiator, do you still need to run water through the rad to flush the particles (whatever you call it) left behind ? Then add coolant mixture into the rad and reservoir ?

TIA.

sir otep, san po banda to? hehe baka kasi yung drain plug ng engine oil mabuksan ko haha. how can i identify na sa coolant sya?

[OTEP]

Block plug location varies with engine model.

Kung talagang marumi or makalawang ang tubig , pwedeng paandarin ang engine . Ung hose na papuntang water pump ay dapat tanggalin sa pagkakakonekta sa radiator at kabitan ng umaagos na tubig then ung hose from elbow to radiator ay tanggalin para doon lalabas ang tubig. Obviously, you have to remove the thermostat temporarily. Kaya medyo matrabaho pero malilinisan ng husto ang water line.

[chiekot]

I have just recently bought a liteace and I am having difficulty locating the drain plug. One thing more, how many liters kaya ang capacity ng cooling system nito? help anybody?

[nptolentino]

Mas better at least kung may coolant mix ka lalo na if you are just using tap water para may proteksyon sa kalawang. Dibale sana kung yung radiator lang ang kakalawangin, paano kung yung freeze plugs mo sa water jacket nabutas dahil sa kalawang? mahirap magpalit nun lalo na kung sa likod ng engine block ang apektado. So better be safe than sorry

Been using 100% coolant on my 10 year old car and until now, wala pa naman ako naging problema sa radiator. Once every 2 years nga ako mag refill ng coolant sa reservoir. Dont need to check every now and then ang radiator kc di naman cia nababawasan ng mabilis. Just fill-up the reservoir then check na lang pag naaalala or may nararamdaman. ^_^

[aylaisabelle]

Yan ang prevention is better than cure.
Good job sir Wezz!

Ganyan din ang gagawin ko sa bagong palit kong radiator galing sa robert's automotive. Sabi nila mas mahusay talaga pag 100% at hindi solution lang.. may mga ingredients kasi na hindi nakakalawang at protectant pa.

Gamit ko ngayon ay ung sa petron na coolant.. So far so good. di na nag ooverheat ang baby ko.

aylaisabelle, we have to be a little careful when making "commercial" recommendations. Any knowledgeable person working in this field wouldn't recommend 100% pure coolant because of the fact that you will lower overall system cooling capacity. The conductivity of both fluids are as follows: Glycol is 0.258 W/m K, water is 0.609 W/m K.

Adding coolant simply raises the boiling point of the water but lowers its thermal conductivity. It also acts as a corrosion inhibitor and provides lubrication for the water pump. The more glycol and the less water you have the lower overall liquid conductivity.

The only instances where a pure coolant implementation works well is in heavy duty applications, as in trucks, where there is a relatively large amount of heat being released in a small area, causing the water component in the solution to evaporate. The coolants for this application, however, are specially formulated.

Wezz, if you have to refill every 2 years, anticipate residue build up along your engine's water jacket and the tubes of your radiator -clogging is imminent. 30-70 is a good mix, 50-50 should be tops. 100% is only advisable if you live in frigid zones.
