i have 03 civic 60kmiles. i just changed my coolant for the first time with Honda Type 2 coolant. the new coolant is kinda blue. the original coolant that came with my car looked green. What's the difference ? i bought this from Honda dealer and on the can it says it can last for 5years/60k miles.

 

they used different food coloring, got bored of green i guess...

 

BLue = Green = same shi........................ dont worry about it!

 

doing a tune up on wifes car, mine is yellow, lols.

says on the package "can mix with blue and green" coolants...

 

At the truck garage i work at, every batch of Renault CoolElf Supra we get is a different colour to the last. Purple, green, pink...mix 'em all together, it don't matter a bit.
