On the way home today while in traffic it hit 223. I don't ever remember seeing it even break 212. Is this normal at all? I haven't checked yet but I wonder if the electric fan is kicking on.

 

Yea in traffic mine spikes up pretty high. You aren't getting much air flow through the radiator. Are you stageII? Mine broke 200 the other day after I got stageII installed.

 

Nothing to worry about, sometimes in traffic or while stopped it will get up to 225+ here in AZ. Its no big deal as long as it drops back to 180 something.

 

I'm going to go try this again and see what happens. New cars make me paranoid

 

No seriously it's fine. My Coolant fluxuates from 160's to 220's. I was paranoid too so I went to my dealership and the guy said it was normal fluxuation. Now worries bro.

 

At what temp do the electric fans turn on? Mine was up to 220 today and neither of the fans were on. THis seems real strange to me. I've never had a car thats operating temperature was above 205.

 

Ecotecs run pretty hot---its normal

 

at what point would you guys consider it to be over heating?

 

pretty sure the fans kick on at 230 or so... i wouldn't worry about it... in traffic, it's going to get higher... once you start driving it should go back down though... in normal driving mine is around 189 - 200... in traffic it will sometimes get to 215 or so... totally normal...

 

Yup Its Normal...i Am Still Thinking Of Getting Another Elec Fan On A Switch For My Own Purposes To Cool It Down Some More But It Is Ok At 180-220

 

yea mine does same thing...I drove on a gravel road in 1st gear mostly for like 2-3 hours and the temperature does spike up pretty high..had me worried as well but like said its normal. It came right down as soon as I started moving faster.

Full synthetic oil in the 2.0's i think so maybe that's why its ok. i dunno i'm no expert

 

I have had the same thing......i almost **** a brick when mine went up to 228 in traffic.

 

You'll get a warning light when your car starts to overheat. As long as you've got the proper mix of coolant and water, your fluid won't boil until some point over 260 degrees. As long as it's under that number, and still liquid, it's cooling your car and you're ok.

 

I'm thinking about running a throw switch for my fan. Then I can run my fan all the time, or when ever I want too. When I'm sitting in traffic I could hit a switch and botta bing botta boom! Cooler temps! Even if it is normal for it to run as high as low 200s. I still would like to see a constant 170-190.

 

^^^^ it's called the a/c button

This whole thing doesn't make sense to me. When running the air conditioning the car doesn't go above 192. Why did Chevy opt to not turn the fans on without the a/c at say 200 or even 210? Is this something that can be changed with HPTuners? If I can run the car at 200 all day long, I'd be real happy.

 

You'll be fine with coolant temps above 223. If theres a problem the DIC will let you know.

I kind of hate having to cycle through everything to see my temps, but oh well. Makes me less paranoid, except when I See them and then have to remind myself 230 isnt that bad

 

Send me your ECM. I'll turn the fan's on 100% all the time. I never see temps over 190.

 

The fans run constantly with the a/c on because the condenser is between your radiator and heat exchanger for the intercooler, and it needs airflow to function. There is also the added load on your engine. The result, of course, is your car running at a steadier temperature.

 

Thanks for all the input guys. I'm fully aware of why the fans run witht he a/c on, just wondering why i never see the fans on any other time, especially since the coolant for the aftercooler is in the middle there. I also know that certain motors, in order for them to operate at their peak need to run a hotter than say 190. When I get my car tuned eventually, I'll see if they can change the threshold to turn them on earlier.

 

A bit of an update for those searching and looking for the final outcome / answer. I watched the temps climb up to about 230 and then it looked like the fan FINALLY kicked on and the temp dropped way down to 192. It looks like the ecu will wait until it hits 230 and then bring it down. When the car sits at idle it isn't making enough heat to raise it, it's when you're cruising down the highway and then come to a stop in traffic that the heat builds.

Q. Why is the coolant temp so high?
A. It's just the way it is. Until you hear bells and lights going off, you're in the clear.

 

I usually run the ac at full blast when in traffic to keep the car from overheating.

 

I have my fans set at 60% below 212* and my temps never get above 183* and to me its getting pretty hot when the temp gets up to 189*
