    • It is the right coolant for our car
Size: 1 GA
We have an older car. My wife doesn't handle change very well. She likes her car so we keep it running as best we can. We developed a problem with coolant levels. I'm leaning towards a loose reservoir tank cap rather than a leak. No evidence on the floor of anything leaking. Have you tried to buy coolant recently? They used to tell you what was in it - no more. Lots of brands for sale all about the same price. But no info on the ingredients. Look at the color they say - well some is orange, some is green, some is somewhere in between. This one had a label that had some key information that matched the owner's manual. We added some. In a day or so we should know if we have a leak or a resolution. Keeping out fingers crossed. ... show more
