drove my 97 GT to work with outside temp around 80 degrees when I noticed the temp gauge floating around 250 or so, my thoughts were that I just changed the stat, new hoses, new radiator, etc.. when I parked the A-F just poured out the reservoir vent (small hole on side), well later that evening when I got off work, I got in and drove it home with no problems (cooler temp around 70 ish). I know my cooling fans work, but they dont spin as fast as I would like and I think this may be the problem with the heating situation.
A/C not in operation either!

Has anyone experienced this? and if so, was it the fans and is there a way to increase the fan speed? or just get another set?
