if you're on a 2.2 then yes..when it's summer and you're in stop and go traffic, say going for a while then stop for a minute then go, then stop for 3 minutes, it can go extremely high.

 

calm down bro. i specifically said it wasn't directed towards you, and then proceeded to answer his question. so calm down man, it doesn't matter how long you were working on cars for, instead of saying something like "i've been working on cars longer than you" next time just give some help. and no, you don't need to check those things, because there's nothing wrong with the car. person after person told him to get his car checked out. for what, there's nothing wrong with it. so i was simply pointing that out.

 

no here in Pa...the highest mine has ever been was 219 and that was in KC with like 103 temps out side!!

 

mine gets to the 220's all the time if im idle or city driving. my normal driving temp is 190ish though.

 

You kids do know that normal combustion temps are about 15-1800* right?

D4 got it right, it is normal, I was at the dragstrip and did about 3 runs in 20 min, got back into staging for the forth and had to wait because a guy grenaded his differential all over the track and with the car off but in the on position(for the fans) with 70* temps mine hit 228*. Once the track was good again we were running and at the start it was at 225, on the return road it was at 201, back in staging 199 and never hit over 215 the rest of the day.

 

mine gets up to 220 alot. been to the dealer a couple of differnt ones and they say its normal.

 

Thank you for making that post.

I didn't feel like it

 

the 2.2 does get up there...mine at times went that high when i had it..but its nothing to bad..but like everyone said..if its constantly there driving and idling..that not good...u shud b fine..cmon its a cobalt..lol

 

eh i was racing a scion tC then normal driving for 5 mins then stoped at pizza hut thats when i saw it

 

That temp is way high for Pennsylvania

 

what is that in celcius??? I run at 90c but go down to 86 when driving.. just think u could probably cook dinner on that motor

 

according to what? it is not too high regardless of where you are. i don't know where you guys are getting your info from

 

This thread is almost as helpful as the Mobil 1/Royal Purple discussion we were having a couple days ago.

 

LMAO. No, actually, it's not.

 

Here's a copy/paste from GM Dealerworld about coolant temps for the 08 balt. If ya notice, the coolant temps before the PCM will command the fan on high is over 221°F that the original poster was mentioning. Most GM techs will say it's normal for being parked idling or at a light for an extended period of time.

Cooling System Description and Operation
Cooling Fan Control
The engine cooling fan system consists of one cooling fan and two relays. The cooling fan has 2 windings in the motor, one winding is for low speed and the other winding is for high speed. Voltage is supplied to the relays from the 30 A cooling fan 1 and 30 A cooling fan 2 fuses. The engine control module (ECM) controls the low speed fan operation by grounding the cool fan 1 relay control circuit. When the cooling fan 1 relay is energized, voltage is delivered to the cooling fan low speed winding. The ECM controls the high speed fan operation by grounding the cool fan 2 relay control circuit. When the cooling fan 2 relay is energized, voltage is delivered to the cooling fan high speed winding. The cooling fan motor is grounded through its own ground circuit.

The PCM commands Low Speed Fans ON under the following conditions:

• Engine coolant temperature (ECT) exceeds approximately 106°C (223°F).

• A/C refrigerant pressure exceeds 1 310 kPa (190 psi).

• After the vehicle is shut off, the ECT at key-off is greater than 140°C (284°F) and system voltage is more than 12 volts. The fans will stay on for approximately 3 minutes.

The PCM commands High Speed Fans ON under the following conditions:

• ECT reaches 110°C (230°F).

• A/C refrigerant pressure exceeds 1 655 kPa (240 psi).

• When certain DTCs set

 

Mine gets that hot once in awhile if i get stuck in a traffic jam on the high way or something but i usually just turn the heat on full blast and it cools down right away

 

Thank you, this is exactly why I do not worry a bit when mine hits 231 degrees in traffic. This is also why most cars have cooling gauges that move to a specific point and never change position unless the temp exceeds a certain mark. "Dummy gauge" is exactly right.

Case in point - my friend has a S2000. It has a standard cooling gauge that, once warmed up, never moves a bit. A couple weeks ago, we installed a mechanical water temp gauge, and I pointed out to him that this will read anywhere from 185-225 depending on driving conditions. Sure enough, as the temp moved up 40 degrees, his stock "needle" did not indicate any difference at all. It's programed only to read hot if the car is actually overheating. (or close to it)

 

QUICK! put eggs on the valve cover

 

And bacon! Everyone loves bacon and eggs!

 

lol lets cook up some "muffler meet"

 

mines never wetn over 200

 

Bacon!

 

I don't ever go over 180!


Mmmmmm bacon!

 

iv hit 229...

 

My LS ran hotter than I have ever seen my SS! But while I was stock I hit 200* durring the summer!
