My coolant has been just a hair shy of the "min" line for the past year, figured I'd top it off today. Opened the cap, but the coolant is a very very light blue?!?!!! huh? When I first bought the car last year, I had Honda do the whole timing belt thing, and had them do the radiator flush too.

I have heard that Europeans use a blue coolant?? But I dont know why that would be in my Honda...


Oil contamination? Thing is, every time I change my oil it is a nice light brown every 3K - pretty good for a car w/ almost 250K on it. Dont see any coolant in the oil. I do not have any visible leaks, the car has absolutely no problems with overheating, and the engine runs fine. Whats up, anybody know?

thanks

 

Honda uses coolant that is blue now. I have some in my garage. They also come in yellow and green.

 

Some Euros do use a blue coolant. I have several BMW's and their OEM stuff is blue. It's phosphate free coolant to help not get the corrosion in the aluminum parts of the cooling system. I use Zerex G-05 phosphate free in all of cars (gold/yellow color). Same principal, just half the cost.

As a side note: Every BMW I have had the regular green coolant in it when I got it (all of them are 15-20 years old when I get them), so with regular flush and fills this is fine also. Just don't ever switch to the Dexcool orange stuff!

 

Thanks yall, that expains it...

 

dexcool is the devil LOL sand
