Different car has different way especially there is a breathing screw u need to open while filling a empty radiator system.

Not all cars have a bleed screw. And the bleed screw also is just to bleed out air faster. Doing the burp method like TS works,just take longer.

Ic.

What will happen If use concentrated one 100% without mixing with water, those come is 500ml or so bottle.

Too concentrated. Just put one bottle coolant and one bottle water. That is 50:50 mix

1 thigs is u wasted lot of money for it , then it might change to another form of chemical over long run , the chemical might not good for rubber or plastic part inside the cooling system

from what i know

water helped on transfer the heat from engine into the coolant

as for coolant is more focus on raising boiling point and keeping entire water/liquid cold

if you used fully concentrated coolant without premix ..heat transfer from engine to coolant will be bad

Need to know the way to do , even got breath screw if not doing it carefully the system will masuk anging later wasted the coolant again , when start the car it will not giving any sign , after 5-10min run then u will see water temp rising and down , up and dowm very unstable

Workshop manual for Toyota says to pour the coolant slowly, 1 liter per minute in order to minimize air getting into the system. And squeeze the top radiator hoses after that. But still need to burp the system like TS later.

Noted.

Good to know. Thanks.

In Malaysia the radiator coolant mainly for 2 purpose , 1 antirust 2 increas water temperature boiling point. But for country has winter , they has extra function of anti freez

Reverse osmosis water + coolant - can use but not recommended

Distilled water / soft water + coolant - Good

Tis is so wrong . Some distilled water those use on car baterry refill might added acid . Need read the label on bottle carefully.
RO water with coolant is the right way , RO water filter out 99% impurity in water.

Premix at factory coolant can. Bestest d, no mistake and confirm good

Distilled water can use.
What you are saying is battery water. Battery water some have added chemical.

RO water is not really recommended. Sure it has no impurities but its also a hard water and ionicly unstable. The atoms will try to stabilise itself by eating at your aluminium. Best water is soft water which we cannot buy. This water added sodium ions to stablize the water.

Thats why best is premix coolant at factory. They will use the correct type of water to dilute their coolant.

try tengok itu battery water from Deions , i asked them before , they said no added chemical heck they even advertised safe to use with cosmetic , mmg pure deionised water and can be used to mix with coolant. tapi last tiem people said deionised water oso bad for the radiator , kek

Becoz when u say distilled water in topic related to car , ppl will think distilled water = battery water .
Most coolant got write on bottle mixture with purify water

No lar that is old knowledge. Nowadays some battery water is distilled water + chemical.
They no update their knowledge not my fault le..

Old knowledge - battery water is 100% distilled water
New knowledge - some battery water is distilled water + chemical.

Yes, it will work for all cars.

ITs no longer needed for aluminum engines these days. ITs only needed for cast iron engines.

Some local car still cast iron engine , only the head are Aluminium
