How do I know what kind of coolant to use and which type is most important for your engine? |
Coolant technology has changed as engine technology and component materials have changed, particularly with the use of more aluminum in engines. However, there is a misconception that all coolants are the same, and interchangeable. There are two distinctly different types of coolant, older conventional fully formulated and the newer extended life coolant with organic acid technology (OAT). They each protect engines from corrosion very differently and when the two are mixed, both are diluted, and their effectiveness can be significantly reduced. |
