I am always between 181-185. Going to work at 6AM is nice cause it is cool outside. After work around 98f, I still don't go above 185.

 

Well guess i'm in the high boat. In Las Vegas were it gets into the 110 to 120 range during the summer, my temp has been as high as 230. I took to dealer as well and they(service dept) said that was a normal range for the car and not to worry. Yea right, for most cars 230 is dead zone. I find myself checking often, not sure if I like the digital readout thing. May go to Auto Meter gauge so I can see better what's going on with the motor.

 

My temp is around 190 i only went over 200 once that i can remaber. even after driving hard.

 

today my temp went up to 230 while sitting at are red light... first time that has even happend and teh dealer said it's normal.. i personally don't think it is though

 

At what temp should the fans kick, the most I have seen on mine was 223F(once), and that was in stop and go traffic, but it automatically starts going back down when moving and the rest of the time. Pretty much want stays between 183-185

 

I actually asked our dealer what the normal op. temp is for the cobalt. They said the Fans are designed to kick on at 230 Degrees and keep running until it drops to 217 or so.

However the other day the fan in the car finally kicked on and it was more like around 223 degrees or so. After a couple of minutes the temp dropped like a rock back down to the 190's.

4 cylinder engines do run hotter, but even so 230 degrees seems pretty high to me. heh, I think I prefer a standard gauge over the digital one, it makes me paranoid.

and yeah, it seems to run cooler with the A/C on, go figure huh? must be the compressor fan cooling the radiator a bit.

 

mine hovers right around 80 celcius, maybe 83 tops... ya to perma 89 does seem a bit too high, then again i haven't drove mine in weather above 20 celcius yet...

 

I've never seen my 2.2 over 192, even last summer

 

my temp goes up in heavy traffic and i learned that if u turn ur a/c on it will bring ur temp down.

 

really? the a/c causes more gas to be burnt so i would have thought it ran hotter with it on ... didn't know that ... good to know.

 

While i was in the staging lanes my 2.4 got upto 220 sumthin. Cooled down once i mad a run and got some airflow over it. It still seamed to hover in the 200s while i was waiting my turn.

 

In stop and go traffic, I get up to about 220-225. Normal driving without traffic is abot 179-183. I'm in Charleston, SC and it's been in the mid 90's lately too.
