I have a 2000 honda civic, this morning i noticed a very small plume of smoke or steam, not sure which, then saw that my temp gage was almost in the red. I turned on my heater and the temp went down, but still slightly elevated. I pulled into work and popped the hood, and there was a very very small amount of the smoke or steam, not sure which, but it has no odor, coming from near the coolant housing compartment. It was too hot to check the water level, so ill do that later, but based on this info, what does it sound like the problem is?
and… should i be worried about making the 20 mile trip back home ??
