Anyone know what the average coolant temp should be? I kind of miss the old gauges with the redline for temps. So I want to know when i should start getting worried with the digital temp read out.

 

I dont know about the ss/tc but when I had my ss/sc I didnt go above 190 so I would say anything over 200 wouldnt be that good

 

mine bounces around from 195ish to 205ish. anything over like 220 and u should start worrying

 

Wow my 09 Cobalt LT 2.2 LAP runs anywhere from 200-220 easily, I talked to a gm technician that said they changed the operating range a couple years back. Maybe 08?

 

Fans turn on factory around 225 degrees. Anything higher than that means something isn't working right.

 

my 2010 ss/tc has been 187 most of time, idling still has gone to 195.

 

My 05 ss/sc runs at 180 even.. Winter time I am at 174 to 178.. I am in south florida..

 

2.2s hit 200's with ease. my average temp while cruising is 189 and in slooooow traffic it will hit 215 in no time.

 

My TC runs an average of 93C (~199F). It runs hotter in the winter by a couple degrees but I have never seen higher than 110C (230F) and that's after driving the ***** off it and having to stop for a traffic light on a super hot day .

 

Also, if you have the A/C on, it keeps one of the fans running, or both at low speed, depending on conditions. So your temps really shouldn't rise at all. I never used my A/C, so the fans were off completely until it warmed up over 220. Once they come on, they stay on, even if you turn the A/C back off or it shuts off because of WOT or whatever. HPT lets you adjust the temp points, so when you get tuned, have them lowered if you like. I always set mine up low.

 

Damn, you guys are running hot as ****, or my car is just weird. I hardly ever see over 180-185. (hit 193 once stuck in a traffic jam in WV on a hill, was riding the clutch for about 20 minutes... you guys have some messed up roads there btw)

 

havent seen anything >200 since i put the blower on used to be over 200 quite frequently

 

Proper mix of coolant and water won't boil until at least 260 degrees, and under normal operating conditions the car shouldn't see over 230. Cruising speed temps seem to vary by engine, but should generally be around 200, +/- 10 degrees.

Regarding your paranoia, don't worry. If your car gets too hot, it will tell you.

 

hell 174 to 178 for me

 

I'm 180 F since i bought it Dec 2006

 

89 to 90 C for me

 

89-94C for me is average... haven't seen it go higher than 96C

 

All good info thanks folks. My 07 SC on the warmer days here recently has gotten up to 105C.

 

wow my temps stay low. 170ish on the highway when its below 50 outside and just under 190 when its hot outside above 85. if i sit in traffic it might creep to 199 200 but thats very rare and only when its in the high 90s here

 

thats cuz u dont live here i get an average of 175-190. but on traffic days and our "beautiful" hot humid weather i see mines go over 215-221 at times. it wont ever past 221 tho since at that point the fans always turn on and cools the engine down.

 

normal 84 - 85 high as 106, +30 and in traffic. low as 81 at -30

 

So why do the cars run hotter in the winter?

I wrecked my radiator on thanksgiving and have limped the car twice to work. Lost all coolant this morning because now I have no heat. Temps got up to 217-223 and stable but its 12 degrees outside. The engine didnt even feel hot after, There shouldnt be any damage right?

 

You may be allright. Only way to tell is to refill with coolant after you fix the radiator and drive it.

Cars run a little warmer in the winter probably because people aren't using A/C. That means the fans aren't turned on until 225 F.

 

Thanks. Were adding coolant now. Cars getting hot, no heat yet and the resovoir isnt taking coolant. Passenger side tube is hot drivers is cold. Anything were doing wrong?

 

Probably a little late.. I always fill them cold until you get to the "Full Cold" mark. Then start it.
