Engine coolant low
Hi there, i was just filling up my washer fluid when i noticed my engine coolant was below the recommended low line level. Any particular reason this could be?
What type of fluid do i put in there to top it up? Btw, its an 08 sahara 2dr if that matters...
Thanks a lot

Best bet is to get a gallon of the MOPAR stuff from the dealer, and mix it 50/50 with distilled water. Mark both bottles "50/50 Mix" so you know in the future it's already mixed.
That way you don't have to worry about if it's compatible with what's already in there. The dealer may be a little more expensive, but you won't have to do this very often.
Let the engine cool completely down, then bring the level to half way between min and max.
Since you never noticed the level before, keep an eye on it.

50/50 is a good, safe ratio for protection against boiling and freezing.
I have always used 50/50, including at 120°F and -30°F ambient temperatures.
It's also very easy to mix at that ratio when you have an empty bottle the same size as the anti-freeze bottle.
There should be a chart on the bottle for different ratios to enhance the protection you need for what you expect the local conditions to be.
