temperature gauge(thermostat going????

I realize recently the needle on the temperature gauge doesn't quite make it to the middle any more. As i drive faster, the needle retrieves to the cold side and in normal driving condition, it makes its way back to the middle, I think its my thermostat starting to go on me.

What do you think, guys???????

first thing to check is your rad fluid, is it too low? If so the fluid is only circulating while driving / engine is revving, your car will suffer the problems you've mentioned.

thermostat is the next thing to check. after that would be the water valve.

It's also been very very cold outside the past 2 or 3 days. Your engine may not warm up as quickly in this weather. If your heater seems to be a little on the cool side as well then I agree with Justin.

you take it out, and then you boil a pot of hot water, when it boils you drop it in, if it opens, it's good..

if anything it'd be stuck open, a closed thermostat would cause an overheat.

I'm not WWJD
but if temp gauge isn't in the middle (12 O clock), you can bet it's sticking open, beleive their 24 bucks at the stealer might as well pick up a jug of coolant while your their and stop off for 4 L of distilled water on the way home.
4 10mm bolts plus the hose clamps (& hoses) thermostat is changed.
With all that change the coolant too, big blue knob on the driverside of the rad will drain most of it, think another 19mm bolt for draining the block.
Fill the block before instalation of the new T-stat for ease of bleeding the air out of the system I also recomend a brick for the gas pedal so you can fill the rad as it goes dry when the air is displaced out of the cooling system.

If you gonna go through the trouble of taking out the thermostat, I would just replace it with a new one rather than test to see if the old one still works, your gonna have to replace it sooner or later.

Definitly your thermostat.
While you are it, change your thermostat housing to aluminum and get waterpump with metal impeller
