OK, where to begin. I just started the annual hot temp gauge season again. This is the 3rd year that I had my temp gauge read high (as high as 230*). I just installed an SN95 electric fan to see if it helps. Well, what the car does now is it heats up (at least the gauge does) while cruising on the highway. Stop and go, runs normal temp. I also noticed some black 'stuff', maybe oil, in my coolant. My oil looks good now, no chocolate milk and no white steam from the tails. I used an electronic temp gauge and popped it into my radiator when the temp gauge read 220*, it's running at t-stat temp (195). So, am I looking at a weak head gasket, a bad temp gauge (this is the 4th, an auto meter), or perhaps a clog in my cooling system. I also flushed the system yesterday. One last thing, if the temp is up and I run the heat, the temp drops pretty quick. Enjoy!
