this is a new one for me. A couple of days ago I checked my water level and saw that I was a little low, so I added 50/50 mix. Last night I decided to run around a little and after warm up noticed the car was running around 205-210 which it has never done before. I pulled into a local drive in to let it cool off for a while. When I started it back up the temp was at 180, turned on my head lights and the temp went to 205, turned the lights back off and back to 180. weird thing is the temp gauge is the only thing effected by the lights. anyone ran across this one before? and the gauges are VDO's if that helps.
