I just noticed that my coolant was low, so i went to buy some coolant and filled it up, but after i did that i saw on the container that it was made for "all GM vehicles that require DEX-COOL as well as other cars that have aluminum radiators, and it's compatible with newer Ford and Chrysler vehicles." The coolant is red colored, and someone on another forum said that they added green coolant. Im color blind so i don't know what was in there before i added more and im worried that i put in the wrong kind of coolant. It is called Prestone 5/150 Extended Life. Is this kind okay to use, or should i drain it all out and put the correct kind in? If so what is the correct kind to add?
