Hi everyone,
Where can i buy distilled water for radiator,as my spare is low on coolant,i am also thinking to buy pre mixed Toyota coolant.

distilled water = RO water

The machine one or bottle?

This

Coolant has antirust, but distilled water doesn't

Sea master, spritzer also can right?but have some coolant in spare tank

spritzer distilled, so 99 speedmart should have it.
or find spare part shop, battery water are distilled water.
or better yet, buy premixed and save the hassle.

reverse osmosis =/= distilled water
2 different process.

Ok thanks for suggestions,much appreciated 👍

is not the best way but unfortunately sometimes the coolant need water
premix volume loss is due to water loss, and concentration goes higher and less effective as coolant, add water is good add coolant is bad

Shopee also got sell. Or you can get from those water machines as long as its RO.
Usually in my car i go for 60:40 ratio of coolant to water.

Yes, 2 different process, but the end product is 99.9% pure water which is good enough for application demanding for either.

Next, do not assume battery water (that you can buy in market) as distilled water. The genuine ones added electrolyte (ie.mild acidic).

Only the fake ones are RO/distilled water. 20cents a liter, pour it into a bottle with nozzle can sell RM2.50

Personal experience - Just use filtered water + coolant good enough. Usually i buy normal RO water or use house water filter for drinking to fill up. i always choose the middle route, so 50:50 for coolant & water ratio. Already doing that method for years and no rust for my cars even more than 10 years. (Usually i change coolant around 5 years or 100k).

If money not an issue, nowadays people are moving to waterless coolant. Just google/fb about Evans waterless coolant.

If not mistaken, tescogot.

I've seen them selling distilled water before at the drinking water section.

If you really want diy daily do drive your vehicle

Go service center buy the genuine long life coolant, drain the old radiator coolant on bucket or ruin the environment

Refill any water you want start the engine let it run for another 2 minutes until water is clear

Tighten everything replace the drain nut oring, fill in the coolant mix the water, start your engine wait until no bubble, close the cap, next day or 3rd day refill water again if needed because thermostat not opening yet during change

Coolant RM 35 , tap water aiks tak tahu macam mana kirae

After that yearly drive or not just replaced it , coolant is very damm cheap thing, no need so much hassle RO water lah, diamond water lah just bs

I changed coolant at sc a year ago,last service they didn't top up the spare tank,knn betul,bcs this Saturday i am going jb-kl

AEON got drinking water by distilation process, I think one of the cheapest AEON own brand drinking water.

If year ago all you need just top up the water, open the radiator cap if rust no matter how you change still coming back because the extension piping make from steel and already coruded

If there are no sign of rust mean still in good condition just top up the water at radiator close the cap , refill the spare tank to the marked level and you good to go jb to kl then once back only change radiator flush and coolant at sc without issue

If you want to know if your vehicle is leaking radiator coolant before drive start your engine without ac turning on let it idle for 15 minutes, some radiator part leaking start from cold because once the engine is hot enough the material expand for whatever reason the leaking part is stop

After 20 minutes no sign of red coolant you good to go without worry

Unless every week you need to refill the water mean there are leaking, if only refill every 3 months is very normal

Good practice still open the hood check the fluid level monthly

Cheers

My cooling system so far no rust and coolant looks good,i think no leakage also else it will overheated long time ago

It is ok to add in distilled water for loss coolant due to evaporation.

It won't do any harm provided you replace the coolant probably after 3-5 years.
