1. Color means nothing at all.....I mean nothing at all...it's food coloring.

2. There are several families of coolant...conventional, OAT, NOAT, HOAT, Asian, European.....a bunch of different types.

3. Some coolants do very bad things when mixed....even if they are the same color (see 1 above).


4. In general, you don't want a coolant containing nitrite in a car. That is for heavy duty diesel (semi-truck or larger vehicle) engines...cranes, Navy ships, etc. The one exception is G-05 which uses a low level of nitrite & was used by Chrysler for a few years. Nitrite (and molybdenum) are used to protect wet sleeve liners.


5. Any coolant that lists ASTM D3306 is fine for just about any car...as long as it is not mixed with any other coolant & you use distilled water (or deionized water)...never use tap water or God forbid well water.

Hope This Helps!
