runs cold
I have a 1992 ford Explorer 4X4, and in the winter or in the cold weather, like it has been here in CT, the temp gauge hovers over the first normal mark, not even in the normal zone just at the mark, maybe it will go a little over it sometimes but just a little.....but in the summer its at the half way point for the whole time, it was running cold last year as well, but it would go up higher than it is now, the heat comes out hot, does any one else has this problem is this normal or is there some things i can do my self to fix it or should i leave it alone

I had the same problem, it's your thermostat. It took a long time for mine to warm up in the summer, on our first few cool mornings it wouldn't warm up at all. I changed the thermostat a few weeks ago, bingo. Good luck.

I have had the same problem. My 93 would show dead cold in the winter, despite warm heat. On hot days in the summer, it would function normally after it warmed up, but on my morning drive to work (25 miles) it wouldn't show even a bar.
Sounds like a thermostat or maybe your gauge. If it is the thermostat, you should see a small increase in mileage when it is fixed. When the therm conks out in the open position, it sends a message to the ECU to run richer for the start up idle mode until it hits a certain temp. point, then the ECU re-adjusts the fuel mix. If you get a chance to order one, with an older Explo, I'd suggest a fail-safe thermo that fails open instead of closed. Few extra bucks, but worth it.
If that doesn't fix it, I'd leave it alone. I think the gauge is more trouble to fix that the problem. Might also want to flush the rad.
Tell us how it comes out.
