一樣一半, 不過市面有coolant係已經開稀既來賣, 睇樽上label.
如水箱只是蒸發了水份, 加返蒸餾水可以照行, 日後最好入返相同份量既coolant.
唔好用水喉水、礦泉水, 山坑水更加死得.

但係好多車房都係用水喉水加添加濟~

唔用蒸餾水, 長期會有 mineral deposit 塞住個 radiator. 不過香港人換車快, 通常換咗車問題都未出現, 話時話, 試過問車房同 dealer service, 無乜人知乜野係 cooling system flush, 最多都只係換 coolant, 唔知係唔係香港無 extreme temperatures, cooling system 無甘易塞

唔係唔知!而係唔會用!一般坊間流傳洗計水同洗水箱水呢啲嘢係會有少少嗱嘅用途!而咁啱嗱走左啲污穢導致漏油漏水就麻煩了!尤其舊車

I use coolant that is recommended by manufacturer.

水箱水一定係專用水箱水+蒸餾水(如要開的話)
有d水箱水唔駛溝直接用. 但多數都係要溝既.
用水, 唔會有即時危險, 但幾年後你想救都冇得救. 因為生锈會塞水箱, 同整壞水泵..
水箱穿左燒盤頭時有發生. 因為水去得快連溫度都測唔到, 水溫燈未必識著.

水箱水除左防锈之外最重要係增加boiling point. 一般車水箱水可以去到110C
如果只用蒸餾水,可能會氣化 (實際水箱仲比大氣壓高, 所以都應該唔會).
氣化左既水係唔可以用來散熱.. 又係會燒爭口.

香港o既自來水係屬於軟水,係香港換水箱水,從來都只係用自來水溝水箱冷凍液;用蒸餾水溝,只會係浪費金錢,百份之一百係唔會有任何特別好處的.

歐美或內陸地方,由於自來水屬硬水,水中含礦物質成份較高,所以先會建議用蒸餾水的.

重申,係香港,唔好迷信蒸餾水溝冷凍液會為冷卻系統帶來任何好處,根本只係一樣浪費金錢o既做法.

還有,水箱水無錯係可以延遲沸騰o既時間,但其主要功用係防止沸騰時o既氣泡產生,因為當水路入面產生氣泡時,氣泡會減少水箱水跟水路o既接觸面積,換句話講,即係會大大減低水箱水帶走引擎熱力o既效率.

溝乜水都得,但一定唔好溝唔同牌子coolant。

香港既自來水,有時都有沙石,唔會因小失大

養得車,有點支出係要比

有沙石,用任何簡單過濾器,或甚至先用水桶裝起,然後先再倒落水箱已經好足夠,用蒸餾水只係一種浪費.

養車當然係需要付出,但付出還付出,都要有點理性;感覺還感覺,但事實就係事實,試問廠方指引、坊間車房或代理會用蒸餾水溝水箱冷凍液呢!?

雖然香港既水係軟水. 但應該考慮運送軟水既金屬喉管.
五至十年先換一次水箱水, 唔係慳果幾升呀?

唔係慳唔慳幾十蚊o既問題.
一個月用油都二三千,當然唔介意用多幾十蚊,問題係感覺定係事實;即係咁,你話用左會安心D,咁呢個係個人選擇問題,但就唔好講到係正確做法一樣,因為係香港,根本係完全無呢個必要.

初頭我都信係.
直至有車友話我知佢架車之前比車房用水喉水入. 過幾年穿左水箱, 生晒锈.

你呢個邏輯係咪有D問題呢?
如果只係用水喉水,無加任何冷凍液,呢個可能性我唔排除;但水箱生唔生鏽、穿唔穿,係同用唔用蒸餾水係百份之一百無關系!

The main function of the Cooling System is to carry heat away from the engine and maintain the desired operating temperature. This is accomplished by circulating antifreeze/coolant through the engine, where heat is generated, and carrying it to the radiator to be cooled.

Modern automobiles operate in a wide variety of ambient temperatures, from well below freezing to well over 100 F. The fluid used to cool the engine must have a very low freezing point, a high boiling point, and it must have the ability to transfer heat.

An adequate amount of an antifreeze/coolant and water mixture is necessary to reduce the possibility of engine overheating and freezing, and contain additives to prevent rust and corrosion in the cooling system.

Water is one of the most effective fluids for holding heat, but water freezes at too high a temperature to be used in automobile engines alone.

The fluid used in most vehicles is a mixture of water and ethylene glycol, also known as "antifreeze" or "coolant". By adding antifreeze to water, the boiling and freezing points are improved significantly.

The temperature of the coolant can sometimes reach 250 to 275 F (121 to 135 C). Even with antifreeze added, these temperatures would boil the coolant. To prevent this, the cooling system is pressurized, which further raises the boiling point of the coolant. Most systems have around 14 to 15 pounds per square inch (psi), which raises the boiling point approximately 45 F so the coolant can endure the high temperatures produced in the engine. - See more at: http://motorist.org/articles/Cooling-System-Maintenance#sthash.olm7KEXq.dpuf

No sane person would use corrosive liquid in cleaning cooling systems. Of course, people doing it for a quick bucks are exceptions. Reverse radiator flush uses fresh water only.

It is true that in some old cars, mineral deposits actually clogged leaks and kept the cooling system from leaking and flushing the cooling system would flush out those clogs and cause leaks.
