Engine coolant: Is water enough?

[sboogie]

You'll still need to use some additives because plain water will just rust the insides of the radiator. Rust will just build up at the bottom and in the small tubes. With enough accumulation, the tubes can get blocked.

experienced that already even if you clean or flush the radiator regularly

Tanong ko lang mga bro, may dapat bang gamitin pag mag-flush ng tubig sa radiator para matanggal yung rust, kac yung kotse ko hindi ko alam kung may coolant, nagdadagdag lang ako ng tubig pag medyo may bawas na, kasi nabili ko yung car january of this year, gusto ko nga mag-flush ng radiator para mapalitan ko na ng may coolant mixture, although di pa naman ako nakaranas mag-overheat eh, ayoko pang intaying mangyari yun.
Thanks!!!

ok lang pang flush ang tap water as long na di ka nakakaranas na tumataas ang temperature

do it at least two times for two days para matanggal ng husto ang mga latak at dumi sa loob ng radiator

basta't malinis na yung lumalabas na tubig sa radiator ready na yan lagyan ng coolant

if i remember correectly most guys over at BITOG advocate "silicate" free coolants for hondas because apparently hondas have small rubber parts in their cooling systems. silicate in the coolant has a nasty habit of drying out and flaking, and when it flakes, the little particles clog up the system, gel, or destroy the rubber/plastic based parts of the system. years ago i recall wondering why the factory bought coolant for the nissans (white bottle, green fluid) would dry out and leave a hard, flaky residue where i spilled it or at the bottle's mouth. baka ito yun, kako.

i remember having a hard time looking for a coolant without the said ingredient (check the back lable of the bottle where the list of components is listed). some variants of prestone had it, as did shell (yoko bumili na Honda coolant, parang overkill na kasi eh). the only one who didn't have it was caltex long life, balck bottle, concentrate, red fluid. i put that in. it was also the brand recommended at BITOG, where it's called chevron/texaco or something.

mga sirs tanong ko na lang din. how often do we flush water on our radiator? mine's got a bit of a rust build up kasi. bale ang ginagawa ko ay coolant sa reservoir at distilled water naman sa mismong radiator, pero may rust pa rin. ok lang po ba ito or much bettter if i put coolant mixture na rin sa radiator mismo? TIA!

Paghaluin mo na iyong coolant 50/ 50 mixture at distiled water . Kung mag flush ka ng tubig sa radiator siguraduhing mong malinis na and radiator mo bago mo ilagay iyong coolant. Gumamit ka ng water hose ilagay mo sa radiator habang umaandar makina para matangal lahat ang dumi at kalawang sa loob ng radiator..Kung ako tatanungin mo kung gaano kadalasan papalitan tubig sa radiator . Kung tap water gagamitin mo kahit every 4 days para malinis maigi radiator mo .pagalam mo ng malinis at saka lagyan mo ng coolant .
