Ok, so i told my girlfriend she could sit in the car and leave it on to stay warm as long as she watched the coolant and shut it off if it got too hot...well she didnt watch the coolant and when i returned it was at 217 degrees. i shut the car off immideiatly and let it cool. Its running fine...could this have caused any damage?

 

no, since the low fans aren't supposto be commanded on until about 225.....you're fine

 

thanks...i was a little worried!

 

so dont get worried unless it gets to 225?

 

Yeah, these cars run hott as ****... Mine used to on more than one occasion hit 210-215*

Now I since my t00n's I havne't been over 180-190*

 

dont get worried until you hear a large boom and see coolant and smoke go everywhere

 

well, if you're sitting and idling for a long period of time...the temps will probably go up a little since you don't have any air flowing through the radiator

 

haha

 

or if your car is a rolling fog machine

 

 

highest i have hit is 201...not sure if ss/sc and ss/na would be much different or not

 

engines run more efficiently when they are hot, all the low temp t-stat stuff is bs, you need a hot motor for efficient combustion. optimal is actualy around 195

basicly dont worry till it hits 235-240, thats when you have issues.

 

If it hits 240 you have issues. Dont worry about 217 with it idling. Since she had the heater on im surprised it didnt run a tad cooler though.

 

Don't worry about it... Though I'm surprised its getting that high since it's not even hot out (summer time).

 

these ecotecs do get hott...its normal for them..with a CAI my temps came down a lot!

 

in my 2.2 i hit as high as 220. freaked me out the first time too, but after some research i found out it's not a big deal. it will go down as soon as youstart driving. the cobalt depends on moving air while you're driving to cool down. in traffic, or at lights if it goes up nothing to worry about.

 

As long as it doesn't go over 240 you are fine. GM doesn't command low speed fans till 223 and high speed till 230. This is to help get better emissions and for no other reason. During the summer it used to be common that I would see 230 to 232 sitting in traffic, at least until I changed the fans to come on at 209 for low speed and 221 for high speed. Now I haven't seen any tempuratures above 211.
