Go to a reliable mechanic and get an accurate temperature reading from thier computer. Check that off from your engine gauge and compair. If its running around 145, try an replace your thermostat with a new one. Its possible its stuck open. If you can find one around 180 go for that.

Could somebody tell you the right temperature for 3.4 impala 2000 thE CAR DONT HAVE THERMOSTAT THE TEMPERATURE STAY IN MIDDLE AND THEN IS GOING DOWN.?
Any Auto Parts store can tell you the correct temperature thermostat for your Impala. Probably it requires a 195 degree thermostat. One thing for sure is no thermostat is not what you want. Running without a thermostat, will cause the engine to not reach full operating temperature. The engine will not perform to peak efficiency at below normal operating temperature. Normally that is around 220-230 Degrees. Your engine is computer controlled and the computer bases fuel/air mixture and timing on the engine temperature. Install the correct thermostat.

How do you know if your car thermostat is broken?
If the thermostat is broken in the closed position the engine would overheat rapidly. If it was broken in the open position the engine cooling system would not reach normal operating temperature and the heater would produce only warm air. Take the thermostat out and put it in a pan of water on the stove. When the water gets to around 200 deg F, the thermostat should open. If it doesn't it needs replaced. Observe carefully that you have not installed the thermostat upsidedown.

What is the normal operating temperature for a 2002 Chevy Impala?
On the police dash, the needle should not be more than one notch over the middle mark. On every other 3.8L motor dash, the needle should generally hover around the middle. My 3.4L temp now runs steady at about 185 on the panel gage after I replaced the thermostat. Prior to this, it was running down around 150 and fluctuating. This caused a "check engine" light. Auto Zone connected their scanner which read " low temp; replace thermostat". They erased the fault code free. I have about 75000mi on my Imp. The themostat is a 195 degree unit. Note that when the gage needle is on the center mark, it indicates 200 degrees.
The thermostat housing leaks on my 1985 silverado after I replaced the thermostat?
Most older Chevy silverados use a rubber gasket around the thermostat itself... the upper housing also has a rubber gasket built into it. Did you move the gasket from the old one & put it on the new one? There is also a paper gasket you can use, but you need a lot of permaseal & it isn't as good. Most parts store will have the rubber gasket & it's about $1.00
