Coolant question

[cool_canadian]

I just noticed that my coolant is below "MIN" but I didn't get a warning yet in "CHECK", should I add coolant as soon as possible?

Not a huge crisis unless it is really low, top it up when you can, where do you think it is leaking from?

[cool_canadian]

There is no leaking...

[nothing77]

It is a sealed system, so it is leaving from somewhere

Based on your experiences, how many times you add a coolant in your cars?

I need to add 50% of water, right?

[nothing77]

I add coolant about once a year, mine generally stays right at or near the min line

hmm, i usually have to top mine up every 6-8 months or so it seems, so maybe mine is leaking??
