After hitting something, a few weeks ago, while driving on the highway in my 06 Cobalt Lt at night my coolant temp was at 300 degrees?!?!? Would this cause my head gasket to blow??? it is at the dealer right now i have already had the rear main seal replaced along with the oil pans for the engine & transmission (auto). What would this also cause, i had to have the radiator replaced by insurance already from the.... accident.

btw. the car had no warning that it was running so hot!!!!

 

radiator? the only time mine got that high is when i hit a raccoon 2 weeks after i got the car......1500 dollars later

 

HOLY BEJESUS... I hope thats a misread otherwise you are not in good shape... somethings gotta warp at that point

 

mine was bout grand also had to do some work to the bumper also, did you keep driving like i did though. when i turned off my car, 10 min later, it would not restart..... i think the begining of many problems you?

nope i had someone else with me who saw it too.... 300 degrees F

i think it reaches up to about 324 if i am correct... it started to melt the padding behind my engine, on the firewall....

 

anything over 230 is pretty bad, i would imagine at 300 it wouldn't be a good thing i don't now what would happen so i won't speculate, but it can't be good

 

all i can say is wow.....thats hot....even when i didnt have a fan the hottest i saw was 240

 

all the mods that my car has are visual too..

projectors,
head unit,
17" black enkei pkr

 

well hold on... i dont think thats THHHATTT hot... the 2.2s get hot anway and its not unusual for people to have temps of 235 with the AC off in the city. Dont think it would cause as much damage as everyone is saying. but it can be to good for an extended period of time..

but who knows i could be totally wrong

 

i drove on it for about ten to fifteen minutes

i would give you all pictures of the engine padding, melted, but as i said it has been at the dealer for almost two weeks

 

ummm...that is uber hot..and temps about 235 in the city are bad!!! i hit 232 after going 162 on a dyno and about crapped myself...we put some fans on it and let it sit for about 15 min before starting agian....

 

only on really hot day does it get to 235; but it would not start again after i turned her off, after hitting the rock or something....?????


in jan, i did run out of gas accidentally, could that have any effect on the engine???

 

to those saying it isnt that hot... it is. I hate going above 200. In summer traffic i have hit 225 and thats when i open the windows and crank the heater full blast. watch that number drop 35* in about 90 seconds.

 

other than not hitting thing on the road, what can i do to prevent this from happening again, and what can i do for cheap mods (I am trying to buy another car)

that number, 235, is durring summer with no a/c (do not ask) and the windows down.....

 

I am surprised that the pistons didn't expand to the point of stopping the motor.

300*F is very hot and it could have caused damage to the engine. I have accidentally ran an all aluminum engine without water and I'm sure it was even hotter and it survived. So you may get lucky!?

Hope that nothing got damaged!

 

300 is very hot for these motors to run. I obviously dont know the whole story as your post only describes part of it, BUT i would assume (being a technician myself) that you hit something (stated in your post) that ruined your radiator causing a coolant look or coolant flow issue. The dealership you turned your vehicle into diagnoes the leak/flow issue. After repair was made vehicle continued to overheat due to initial overheat when impact was made on original radiator. A headgasket issue is hard to detect when a radiator has been smashed, unless you clearly state "my vehicle was severely overheated". Aluminum heads are not difficult to crack when under severe heat.

 

you would think the fans on the car would keep it cool enough..none the less...

 

did you melt your head you might need a new one if not a block

 

not if the coolant was not flowing or was empty.

Then engine burns fuel at ~1200* so without the coolant in the engine the metal heats up fast!!!

 

I am surprised the engine didnt automatically lock up after it hit about 280* damn....

 

i was having a very bad day too. i was about to bring it down the next day, but you all know what happened. I had learned the day before that my car is a lemon, when i pick it up, i will talk to my dealer about it... what should i say to them????

 

Have you ever contacted a lemon lawyer?

 

no... i was trying with chevy ob the phone then the accident happened, so i closed the case they were great though about helping me...... my dealer didn't even fix it after the final repair attempt!!!!!

never go to jon hall chevrolet

 

I know here in michigan you can go to a site and it ask you a bunch of questions then someone will contact you wether you have serious case or not then you can contact a lawyer
