My coolant light comes on and then goes off after I have been driving for about 1 minute.

It has only started happening since it has been very cold here in Pittsburgh. Once I start driving it turns off. Should I get it looked at?

The colder it gets, the more the coolant contracts. As the engine warms up, the coolant expands. Not a big deal if it's low when the engine's cold,since a cold engine has no need for coolant.

mine was doing it only when the temps got below freezing but it was due to moisture in the switch below the coolant reservoir sensor. I suspect is was due to moisture that had seeped in there - it now has fixed itself - just as I was going to spray contact cleaner in the wiring connector.
