Hi,

So the low coolant light has come on periodically over the last 3 weeks in my ML. It comes on, stays on for a little while (minutes) and then goes off. Only to come on again at another point in time.

The first time I saw the low coolant warning light, the coolant was down about 10 oz., give or take. I topped it off. Subsequently it is not down at all.

Can anyone tell me where is the sensor for this and why it might come on periodically?

Many thanks!
