Falling Temp?

I've noticed lately since its winter here now, that even after letting the car get warmed up, as I'm going down the road I can watch the temp gauge actually drop, and the heater will get cooler. If I stop at a long light I watch it go back up.I don't remember the car doing this in the past...It doesn't overheat in the summer or anything, I have plenty of anti-freeze in there, even though it does have a small leak somewhere I keep on top of it.I don't think this is normal, if it is let me know.

sounds like your thermostat is stuck open. or you have too high of a temp thermostat in there. or your fans are staying on. which i dont think that is the case. i would figure out where your leak is comming from and fix that, then replace your thermostat to a 195 degree thermostat

Thanx, Its the same thermostat that was in there when I got the car( 3 years ago), and the car didn't do this then, so I'm guessing its stuck open, is there a way to unstick it, or do I just need to replace?

no best thing to do is replace it. it is pretty cheap will cost ya like 10 or 15$ for thermostat and gasket. and the just some coolant that u will lose when you do it
