Coolant Light comes on for 15seconds everyday..?
It seems that if I reach a higher than average rpm, even for a second, the coolant light comes on sometimes after then..generally it comes on just after i get onto the highway...the indicator then shuts off after about 10-20 seconds..?? coolant level is right where it should be. I checked both when engine was cold, and warm.. possible air in the lines..?? thanks!

There are numerous threads that explain this. To keep it short and sweet, these sensors have a tendancy to crap out. The sensor is built into the reservoir itself and are rather expensive to replace. Over $300 if I remember correctly. You have 2 options a.) shell out the money for a new sensor or b.) do as most of us have and learn to live with it.

Well I think if you decide to live with it you should check your coolant more often, like every fill up. Just in case if you have a leak and sensor is faulty.

Yeah its the sensor, i tried bleeding out the air but still get it as long as i'm above 5k+ rpm for more than 10 seconds. Annoying as hell, gonna get some real water temperature gauge and unplug the sensor in the future.

Checking the coolant level is very easy...translucent tank, right up front, nothing obstructing your view.
During my first four years of ownership, my light came on a handfull of times at the customary high rpm condition. Most of the events were in the week before and the week after my B to B expired, causing the expected "Do I rush to the dealer to get it fixed for free?" and "Damn! I missed the freebie" anxiety.
Since then it will come on randomly once every few weeks. It's likely to do it while just driving along at steady speed and modest rpm, which is different from most people's experience.
Not often eough to bother me, and the light itself is kind of cute. Looks like either a Rolls Royce radiator or a Greek temple. If a passenger happens to notice it, I tell them it means we need to stop for a gyro.

Unplug it and check level on your own!
And if really bored out of your skull..............here's my thread on the subject!

For the sake of argument, I did in fact get a new bottle "rev M", but I also monitor my water temp(not level) real time.

Take it to a Radiator specialist and ask for a System Pressure TEST, to find ANY external Leaks first...and take it from there.
