How do you guys change your car coolant?

Btw fun fact for your car cooling system.

Any type of water only - Bad
Tap water / mineral water + coolant - can use but not recommended
Reverse osmosis water + coolant - can use but not recommended
Distilled water / soft water + coolant - Good
Factory premix coolant only - Best

I used GEP type 2 coolant + spritzer distilled water same like your picture.
Honda type 2 coolant finish...

Coolant also got different types. Cheap or expensive type.
Wan good and cheap, get OAT type coolant. Lasts longer.

Didn't.. but should be same temperature I think?

I just know if u didnt burp the coolant until all air come out, around 20-30 minutes usually, your temperature will be higher by 5 degree for my car.

Kasi chance la. That is diy funnel only after i drink finish.
My.radiator water i use spritzer distilled water.

Change mechanic la. Steering and brake oil need to change after certain mileage although its quite long la. Even for coolant need to partially change it by drain the radiator at least (40-50% change).

Yeah thats why some say for our climate, even 15% coolant 85% water is enough.

I agree we dont need the antifreeze in coolant, but if too less coolant...im afraid the rust prevention additives (prevent coolant become too acidic + prevent rust) is too little. Like maybe few months use finish liao and rust starts forming. As each coolant manufacture didnt state it. So finally its still best if use premix only.

Wah so rajin. Some cars like honda, they dont recommend flushing. Just drain radiator and top up.

Follow je manufacturer recommendations. By the time tukar color i think too late already.

I think they trying to minimize human error.

Sure this info still applies? Last time natural coolant color is green/orange. Now most coolant they got add dye, macam macam color ada. With the dye, coolant expired also still got the dye color

I wonder honda type 2 coolant is what type. OAT?

See what the coolant manufacture recommends. If cheap type 1 year once la easy. If OAT i think can tahan few years. Again see the coolant manufacturer recommendations

Or maybe because nowadays coolant put dye color..

U know based on my picture only?

I do at my mechanic. The coolant he just drain out only...he no kutip also. Yeah i know its toxic..
The picture is i burp the coolant for another 20mins because he just do one fan cycle. Honda said need 2 fan cycles. Go in extra around almost 1L also..

My thermostat super clean. No gunk in the super clean water so no worries

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.

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.
