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

K20

what coolant..already got fan enough laa..coolant are scam..u brainwashed already..antivax n flat earther here..owai~~~

Factory premix coolant only

Rm25 coolant vs rm10 coolant ??

What my regular mechanic told me. Only change engine oil n filter.
Other kind of oil only need to top up if became less.
This is what he said when I ask him to change my steering n brake oil

Perhaps the price difference due to concentrated coolant vs diluted (premix) coolant.

All this is useless if thermostat not in optimal function

i use green color coolant only... bought from AEON lol mitsubishi brand

You just need coolant that prevents rust. You don't need expensive antifreeze coolant.
Our weather doesn't get cold enough for that.

+



best combo la.

jew got do test to compare whether added coolant can make the temp lower than without coolant?

but why TS use mineral water to mix err? So sohai jer.

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.

yeah no

Me is flush once a year.

check thermostat oso , alang alang tu

lol no , kasi flush la itu power steering fluid and brake fluid.

Not all car engine got engine block coolant plug. Like small car engine perodua, no drain plug on engine block. Only way to drain completely is through remove thermostat.

Change your mechanic.!!!

If your oil is less, then it means there is a leakage somewhere. Your oil cannot just evaporate just like that!!

I guna air mani ... Better stickiness

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

nanti gasket koyak?

Typically, you should not have to change the radiator coolant unless it changes color.

there is 1 simple tool that you can use to measure coolant "performance"

if out of specs then can consider change



but malaysia dont care that much because we no winter

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

I think they trying to minimize human error.

What happens to the coolant when it's "too late"? Can explain?

just change my coolant at shop after 150k km lol but still ok no rust / corrosion sign .. right way i think need to flush and replace at least once a year .. mix 40:60 coolant : water

If same then whats the point to add coolant lel ?

If same then whats the point to add coolant lel ?

older the coolant, the coolant becomes more acidic. too old the coolant, it will rust out your car internals, radiator, thermostat, coolant hoses.

Unfortunately this one only measures the anti-freeze power of the coolant, it cant detect the pH value of the coolant, I suppose you could use those pH testing strips to see if the coolant is too acidic.

Err.. U sure not distilled water with premix coolant?

TS ade k20r

Wowow

https://www.team-bhp.com/news/types-coolant...des-and-colours

If your coolant is made with OAT, it doesn't turn acidic.

And the best way of knowing when to change the coolant, is indeed, the color change.

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

Coolant can break down and loose effectiveness. Keep in mind what coolant does,

- raise boiling temp (So water does not expand and cause too much pressure in cooling system)

- corrosion inhibitor (Different metal like aluminium and steel does not like each other. Google for battery corrosion- This has nothing to do with battery but science)

- lubrication for water pumps (If rust do get into water, it becomes sanding agent and coagulant. It could build up in rubber seals drying it out and wear out water pump seals.)

Subjective nowadays for modern cars especially continentals.
Some purposely make the oil evaporate or burn due to lubrication/cooling purpose for high heat/pressure components. (Especially turbocharged engine)
Japanese cars like Mazda rotary engine also designed to burn oil for apex seal lubrication.
Unless the engine original is not like this and only after few years gradually using engine oil for a lot example over 1L need refill for 1000km then this is excessive and need to be inspect & repair.

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

factory premixed coolant,.. how long change once ??

Hmmm. Not sure whether that’s really true or not. Scotty k says even hoat based Toyota gets acidic.

at 1:20, he checks the coolant pH with a test strip.


About the color change, my p2 coolant from factory day one is close to five years and still looks the same. Factory manual says to change every 2 years or 40 k( my is 120k). I’m not going to chance it and going to replace it soon. Who knows, maybe OAT based coolants trait a very long time to change color?

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

Conti car owners
Please take note

Or maybe because nowadays coolant put dye color..

Last time I let workshop flush my radiator, replace it with mixture of spritzer water + coolant

motobike oso 2t 4t oil

U know based on my picture only?

Famous engine. Distinctive valve cover. K24 would be crv

i topup air paip je

You do want your radiator to start rusting.

To prevent the radiator from rusting.

Chris fix

I think for the last 2 you will be able to see the coolant change color.

Best read the owner's manual.

Depending on what type of coolant you have in there I suppose. No coolant lasts forever, but topping up coolant is something we shouldn't have to worry about. If you have to top up coolant, it usually means there's a leak somewhere. Sadly, in msia, people don't pay heed to such thing. Even when it comes to engine oil viscosity you can see mechanics blur blur on what the numbers mean. If you factory manual says to change every 2 years or 40k km, then it's best to do so, especially if they will void your warranty. Coolant is not that expensive anyway, and changing it every 2 years is nothing compared to changing engine oil every 4 months.

Change car. Get a brand new car. Guarantee new coolant, fresh from factory.

hmmmm then it shouldnt be called coolant ler.

My plotong no change.. open radiator still got merah merah kaler like ribena

That toyota red coolant not suitable with aluminium radiator.

masuk bengkel, mekanik terus top up ngan air paip.

Btw TS, where do you dispose off your old coolant?

Why? That’s the oem coolant for their cars which are all aluminum rad

I change the thermostat also when i do coolant drain every 5 years once as preventive maintenance.
Using 50/50 premix. Selangor water too dirty , scared water pump bearing damaged from the accumulated dirt in water.

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..

Spritzer Distilled water + toyota coolant...

Or full premix-ed coolant like TCL.

Do descaling too... before change new coolant.

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

Where to get distilled? Supermarket tesco lotus only sell mineral and drinking water

For real? been using that for quite sometime...

Best is pee inside...

+5hp

Dyno proven.

My area mini market got... I think it is labelled as distilled drinking water?

Drive red logo H but change radiator coolant diy
Lol
Mempersiasuikan bangsa H

What? Diy is the best way

100% coolant no water can or not ?

That’s because he drained the engine block also. If you just drain the radiator won’t have to bleed so much air.

Different car manufacturer got different material for their cooling system & water hose.
My mechanic encountered before certain cars put in different coolant type/color, it can be use but after sometime the water hose expand (bengkak) and water pump seal area leaking. Some coolant might not compatible to certain seals or hose material thus can cause water leakage. No rust, but water hose & water pump all gg.. After that experience, my mechanic usually recommend to pick up original coolant or at least similar color for coolant.

Must buy ready mixed coolant usually sell in 4liter bucket like engine oil

I agree this one. Honda uses the blue coolant stuff likely HOAT, Toyota long life is probably just OAT.

The best way

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.
