Thomastm Posted September 2, 2021 Share Posted September 2, 2021 Not really a car expert, but been reading to avoid tap water (of course). But it says to put in the coolant tank soft water. Will bottled water like Nam Tip be good to throw in there. I couldn't find any premixed solution here in Thailand either. Any recommendations would be appreciated. 1 Link to comment Share on other sites More sharing options...
Popular Post Will B Good Posted September 2, 2021 Popular Post Share Posted September 2, 2021 Probably fine as long as you add the appropriate additives. Just water is not very healthy for the cooling system (long term anyway) 4 Link to comment Share on other sites More sharing options...
Popular Post transam Posted September 2, 2021 Popular Post Share Posted September 2, 2021 You should buy the recommended coolant to top up, don't water down the installed coolant/corrosion inhibiter.. 7 Link to comment Share on other sites More sharing options...
Popular Post johng Posted September 2, 2021 Popular Post Share Posted September 2, 2021 They sell distilled water in Tescos's about 15 baht per liter look in the car care section they will also have ready mixed coolant for an extortionate price. You don't want to be using "normal" water because the minerals in it will cause limescale and fur after a while causing problems for the radiator,water pump and small waterways in the engine. 6 Link to comment Share on other sites More sharing options...

Only expensive if an engine is drinking it for some reason. The stuff that is in the water jacket is as important as the oil in the long term, as you cannot see what's going on inside the engine...???? 2 1 Link to comment Share on other sites More sharing options...
Thomastm Posted September 2, 2021 Author Share Posted September 2, 2021 That's what i thought from doing some research. I will look into the distilled water at Tesco, that's what i was after. I bought some coolant mixture. But the instructions are in Thai. My Chevy eats the coolant, it's quite problematic. I recently got the radiator replaced so trying to be carful with it.

canthai55 Posted September 2, 2021 Share Posted September 2, 2021 Used premixed coolant. All the major car manufacturers have it, but it is costly. I buy mine from a HD truck supplier, as it is the exact same thing but cost is much cheaper. Water is for drinking or swimming. 1 Link to comment Share on other sites More sharing options...

Thomastm Posted September 2, 2021 Author Share Posted September 2, 2021 Hmm, where can i buy premix. Any big car shops in Thailand that would sell it? My Thai isn't so good, so it is hard to explain to the clerks. The car has been a problem honestly. Had it repaired 3 times this year, more trouble then it's worth.

digbeth Posted September 2, 2021 Share Posted September 2, 2021 pink 'Distilled water' for batteries are acidic and would not help the corrosion that you might already have if you need to top up the coolant, the clear ones should be fine 1 Link to comment Share on other sites More sharing options...
Kwasaki Posted September 2, 2021 Share Posted September 2, 2021 Garages have coolant, you can get a ready mix, or if the one you have 100% coolant just go 50-50 with distilled water. Link to comment Share on other sites More sharing options...

VocalNeal Posted September 2, 2021 Share Posted September 2, 2021 I believe in Thailand being tropical one can go with 20% coolant and 80% water or 30/70. We don't need freeze protection. But we do need boiling point raising. Link to comment Share on other sites More sharing options...

How many people flush the system every 2 years and replace the coolant. ???? I know for sure I never do. 1 Link to comment Share on other sites More sharing options...
Lancashirelad Posted September 2, 2021 Share Posted September 2, 2021 OP regarding your coolant loss issue, you need to establish if your engine is losing or using it. If using a compression test would be the next step. 1 Link to comment Share on other sites More sharing options...
JAS21 Posted September 3, 2021 Share Posted September 3, 2021 To top up the cooling system you should go 50/50 antifreeze and water. Don't use distilled water or tap water as advised previously. You can use boied water as it's pH is pretty neutral. If your engine is using water obviously you need to find and rectify the cause. 1 Link to comment Share on other sites More sharing options...

Please explain why you should not used distilled water? Also please explain how the boiling process affects the pH of water and makes it "pretty neutral".

Distilled water is widely recommended rather than boiled water in top up use in radiators but some companies that makes coolant liquid products to use in vehicle radiators point out it's bad because after about 100 years + or so it has some chemical reaction that will destroy your vehicles coolant system. 1 Link to comment Share on other sites More sharing options...

Yes not much need (except on top of Doi Internon) for freezing protection but there is a need for anti corrosion and lubrication. I thought the boiling point was raised by raising the pressure in the system between 13 and 16 psi ? 1 Link to comment Share on other sites More sharing options...

So I stopped at a tire shop near Tesco, garage guy came over with some coolant. Was like okay thanks. He proceeds to want to fill the coolant tank, I said it was hot. I was thinking shouldn't I wait for the car to cool in a couple of hours as I just drove it. But he still proceeds to open it (I thought he knew what he was doing). The coolant tank made a hissing sound as the pressure came out of the system. He then fills it up. I was like this isn't right. Today after driving for 10 minutes. The coolant hose going into the engine had a hole in it, could hear it hissing and coolant pissing out. In short, these clowns at the garage had no clue. So angry right now. Coolant tank is completely empty now. Sigh. Link to comment Share on other sites More sharing options...
lopburi3 Posted September 5, 2021 Share Posted September 5, 2021 Just check the type of drinking water you are buying - if RO filtered it is fine (only thing better is distilled at much higher cost). Almost all minerals are removed with RO filtration. Most of the normal bottled drinking water these days is RO. 1 Link to comment Share on other sites More sharing options...
