radiatior fluid. What could it be? Hey everyone. The temp gauge maxed tonight driving home from work, then went back to normal about 3 min later (like a pin dropping). Also, the heater is broken, and the engine light is on. It's dark ( still hot) so I didn't want to take a look tonight. But, just wonderin' your thoughts on what the problem is and, most importantly, can I drive it to the dealership (10 miles)? Thanks ahead of time!
