My 2005 Dakota 4.7L v8 automatic, 4WD, has been doing an odd thing... the Temperature light and chime (the little thermometer icon) comes on at odd times,(but not very often) while the temp gauge still reads in the normal range. It goes out in a few minutes or seconds with no change in temp or anything else. What is it trying to say? anyone else encountered this? Is it alerting me to low coolant level, time to flush the system, alien invasion? I called a dodge "dealer" and was told I had to bring it in to them for a dianostic for any insight. PULLease- If they don't know what this could be, why would I trust them to find the real problem. (I know, I know, I have a bad taste in my mouth for dealership service departments) Any help would be appreciated.
