lemonjelly Posted January 30, 2018 Share Posted January 30, 2018 can anyone recommend a good coolant (Honda Civic 1.8), obviously doesn’t need anti-freeze. Don’t know what the dealer threw in, just wondering what the possible options are..... cheers Sent from my satellite link using Thailand Forum - Thaivisa mobile app Link to comment Share on other sites More sharing options...

johng Posted January 30, 2018 Share Posted January 30, 2018 Rain/distilled water is ok (actually best for cooling)but maybe some anti corrosion inhibitors would be useful ? Link to comment Share on other sites More sharing options...

johng Posted January 30, 2018 Share Posted January 30, 2018 I've read that pure h2o is best for cooling..but myself have always used coolant / antifreeze just because of the "supposed" anticorrosion and lubricating prooerties Link to comment Share on other sites More sharing options...

Coolant/antifreeze raises the boiling point and inhibits corrosion. Use what Honda suggest ... it will be in your manual. I'll look in mine to see if I can find what you need. Honda All Season antifreeze/coolant Type 2 it says for our 1.5Turbo ... also seems to say the same stuff for your 1.8 Link to comment Share on other sites More sharing options...
VocalNeal Posted January 31, 2018 Share Posted January 31, 2018 If one does a bit of research then it says that the lower the coolant ratio the better the actual cooling. As In Thailand we don't need the antifreeze protection we can go down to at least 20% coolant / 80% water. Link to comment Share on other sites More sharing options...
