Do you use radiator coolant?

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.

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?

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.

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?

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. ^_^

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.
