Daily driver, 280K. A few months ago I noticed the low coolant light on and a 'chemical' whiff came through the vents (we had the heat on because it was winter) - I didn't have extra coolant with me so I just watched the engine temp and made it home without the temp going past normal level. I let it cool in the driveway for a bit, and I come out to top it off and noticed that the coolant level is just a tad under fill mark, but not low enough that would warrant the low coolant light. So I topped it off anyways. A few days later, same thing happened - low coolant light came on, and I checked, normal levels. This happened about once every 2 weeks since then, and I have yet to add any more additional coolant. Doesn't seem to be a pattern either.
Short summary, low coolant light comes on, but I never need to add more coolant. Any ideas?
