Hi there everyone.
So I was just checking out my Coolant Temp and I just want to make sure that it's normal.
The temp is 207F with the AC on. And 194 without. Oh yeah it's a Cobalt SS / SC.
Let me know thanks.

 

Normally, my car will run at 185-187 on the highway or moving, 194-210 idling in traffic, and 190-200 with ac on. The numbers you posted are perfectly normal, no irregularities.

 

Alright man thank's allot... Happy to hear that

 

is it stock? i have stu mod and h/e
i cruise at 171-176 with no ac. and idle with no ac at 181-186, unless im at a drive thru which it gets up to 207 before my fans turn on to cool it down.

 

when i crusiing with gms2 and ottp h/e im at 181.. idle it will go up to 210... idk with ac on cuz i never really used it our summer never got that hot

 

fyi stu mod, h/e, killer chiller, ice packs on your supercharger, wont affect your engine coolant temps. different circuit..

 

Yeah, exactly. lol. It is not the same.

 

bump for this my temps is gettin up 2 220deg , i have to turn on the a/c for the temps to go down.
thinking of clogged cat?

 

Normal

 

I have a question than, since I was just informed about me being an idiot. Since the H/e doesnt affect the coolant temps, if i remember correctly it affects the IAT temps??
How would I know if its working right If i dont have a scan gauge?

 

You won't.

 

^^ Know what isnt working right?

The heat exchanger pump is the thing that fails.. you can check this by checking the cap of the filler neck...

 

so at what coolant temp should i be alarmed?
it goes as high as 220

 

Under what conditions does this happen?

I've seen mine go as high as 224 in rush hour traffic going super slow.

 

Mine usually doesnt go over 200, if it does, I make sure the A/C is on and it comes back down. If I am sitting still at a light, with AC on, it wont go over 190 or 192, cruising, 180 solid. It is as low at 175 sometimes.

 

what I mean is: I got the H/E as a Cooling mod for when I get the OTTP1 kit. Right now im GMS2 with a 2.9 and injen intake... Since the H/E is a Cooling mod, is there any way to tell if its doing its job?

 

normal driving conditions is when it happens. i guess i just now started payin attention 2 it. but what is the temp b to get worried240?

 

to see the temps on the supercharger side. i.e. iat temps. you will have to get a scan gauge like the interceptor. there is really no other way to check it
