Sup guys, I have a Cobalt LS w/sport package. Just wondering I looked in the manual couldnt find out what is the normal temp the coolent should be at. On my last car there was a gauge now we have the digital read and I dont know what temp. the coolent should be running at. I live in Toronto so its ******* cold keep that in mind.. but generaly what should the temp be.

Regards,

 

I don't know specifically about the Cobalt, but the norm for cars is anywhere between 180* to 192*.

 

180 is a little low for a stock car. My s-10 ran about 210 normal. I put a 180 degree therm. in it and then it ran around 180 to 190. The cobalt sc/ss already has a 180 degree themo. in it because thats what it says at running down the road. The other night it was freezing and i had my heater on, and it was staying in the 160's. Then i turned my heater off and it started to go back up.

 

For our little 2.0 four cylinder car. 175-195 is normal under basic driving conditions.

 

My SS 2.4 is usually around 194-196 while driving but I've seen it around 210 when stopped.....this is in the middle of the winter.....

 

My SS 2.4 is the same way Bandit. Highest is 210 when sitting in traffic, and normal running is anywhere from 190-200

 

My Normal is around 86 - 95c.

 

is 235 bad?

 

Heat is the number 1 reason for engine problems and loss of power. So I'm running a 160* Tstat.

 

My 2.4 was running what seemed hot to me, and one day the overheat light came on. Turned out my cooling fan was not working. It was replaced, but I think it was prety crazy to have a broken fan in a new car. So, if yours is running at 235, maybe you should have it checked out.

 

so... has anyone checked for a 180 degree stat for the 2.4 or 2.2?

 

my 2.0 is usally at 180

 

my ss s/c runs about 175-181 when driving it clims a litle bit when stopped

 

I'm at 180 at cruisng speed..190-200 when idling.

 

What he said

 

180's is normal for me. I've only ever seen it over 200 once.

 

during winter 81C during summer up to 110C sitting in rush hour

 

Mine hits 200-210 regularly... definately gonna be going for a 180deg. stat when one becomes available.

 

My 98 Cavalier 2200-OHV engine ran weird... During the winter, it was lucky to hit 150-160F... During the summer, 185F all day long unless I was idling in traffic and then the gage would hit 200-210F.

My base Cobalt with the 5speed runs between 180 and 194 all the time. The hard I run it, the cooler it runs...

With the latest swing in the weather mine seems to camp around 87C which is only 2C lower than what I was seeing in the summer.

 

Mine heats up to 83 C ish now.

 

Tonight in a drivethrough I watched mine creep to 220 from 180. Is this normal??

 

Yeah, heat does kill power in an engine, but the cooler you go the faster your engine wears. This is why cars have moved up from 180F to 195F thermostats. This can be easily seen on the old Dodge slant sixes. The front cylinder where the water came in wore the most (significantly more) than the last cylinder where the water was the warmest.

Also, people on here keep saying that by putting in a cooler stat, the computer will richen your a/f mixture to try and warm the car to the programmed operating temp. This would just waste gas and take away performance. I suggest leaving the factory temp stat in place and maybe exchanging it for a high flow version of OE temp such as the ones by Mr. Gasket.

My 2005 2.2L runs anywhere from 185F to 190F at speed on the highway, but extended in town driving and idling will make it get b/n 210F and 220F. I also heard that the fans don't come on until 226F. I've seen mine get as high as 227F.

Another note, the 2.2L has a single fan and I've seen a Saturn RL and noticed it has twin fans. I wonder if the twin fans will mount up on my car?? I posted a thread on here asking people to e-mail Flex-a-lite; they have started making direct replacement fan kits for the sport compact market and I'd like a FAL set-up for my car. They said the more interest they received, the sooner they would make one available.

my LS is 189 constent...but if im sitting in traffic or something ive seen ti go up to like 210 then it cools back down to 189 in like a split second :P

 

My 2005 2.2 runs about 192-197 in town, never seen it above 200 even while idle...
