Overheating..

(1990 Nissan 300ZX)
My car overheated today for the first time. It was coming from the top radiator hose. The overflow bottle was filled above the max line (not my doing). However, the hose was bone dry. My temperature gauge goes from 120-270 degrees F, and the needle usually stays in the central to high temperatures area, and it bounces around sometimes. Also, I'm not sure if this has anything to do with it, but no matter how hot the temperature gauge says my car is, the heater takes forever to heat up.

I would have the system checked for hydrocarbons. if there are, you have a blown head gasket. a shop can do this for you as a start to determine your proble.
