I've got an '01 Deville (love it) and I'm getting this message constantly. The coolant insn't low and there are no leaks. What gives?

First, check the sensor connector at the bottom of the coolant surge tank. If that is OK then you might be in the surge tank replacement business. Remember to keep the tank filled only halfway, cold.

I have an 01 deville and the message comes up every so often, as well. The coolant is not low. Would you recommend cleaning the surge tank sensor connector? Or replacing it?

Try cleaning the connector ... but it's probably the surge tank. They have been known to fail.
