well i got my car back from the dealer today after frying almost the intire computer system in my car and hooked my fog lights bacvk up.... i lowered the car down onto jackstands and it was fine (e brake was set) and i went to go get my rachet and it slipped off the jackstand and punctured the radiator i believe it is, its the one closer to the front, well i need to buy a new one but i want to make sure that is the radiator before i order one.... any sites that sell them cheap, or any performance ones (dumb ?)

HackAbuse

Ouch, good thing it wasnt something more important like an engine mount, or floorpan

civickilla

ouch

biohazard

so is the frontmost one the radiator?

HackAbuse

Look for the tag on it, it will give you the part number, which will tell you what you need

biohazard

ok thnx... just asking cuz its dark and raining aND about 20 deg outside and i dont wanan go lay on the driveway, will check after school tomorrow..... is there a such thing as a performance radiator?

kanabrewski

i still believe the front most one is the a/c condenser. did it leak any pink coolant, which would signify the radiator? on the SS/SC it goes a/c condenser, stock heat exchanger then the radiator. which is directly under the metal cross plate (upper radiator support) and the fans are attached directly to it on engine side.

HackAbuse

If he can find the part tag, he can easily identify it, so playing guess and seek wont get much accomplished here.

make sure its not leaking before you drive it. Overheated engine = chaos

biohazard

ya i found out it was punctured when i was 3 miles form my house, i halled ass

denniss

The one at the front is the AC condensor. The radiator has plastic tanks on the sides. If it is not broken you will have to have it evacuated and recharged after the new one is installed. The system is under preasure, so don't undo the lines or you will get a face full of freon. You can drive the car without hurting it (if it is the AC and not the radiator), so if you have to you can take it to a radiator shop. I would suggest doing that anyway because you won't be able to recharg it yourself anyway. If you want I will see how much I can get a new one for, but you would have to come to Antioch to get it. I work at Raymond Chevrolet.

I guess I wasn't reading very close. You say it was leaking? Red fluid? That would be the radiator. If so, don't drive the car till it is fixed. i am going to check my employee price on both today, maybe I can help you out.
Dennis

biohazard

yes its leaking RED fluid, but the front one is the one thats all bamnged up on the bottem, i found a radiator for 158 shipped... any help is appreciated, im thinking i will remove the front bumper later today and fnd out what it is

Witt

Rather than trying to find a part number, look at which one is leaking and see if it has coolant lines on it or refrigerant lines. Really not that hard. Not to mention a massive loss of coolant if its the radiator, or AC clutch not locking up if its the condensor.

06cobaltls

do you have an automatic or stick, and are you sure that your ebrake is working, put your car on a hill and set the ebrake, if your car rolls at all, i would call the dealer and ask them why your ebrake isnt working and try to get them to pay for it,

biohazard

auto .... ebrake works trust me but ya dk wtf happened , stand was just tiped over, and wasnt collapsed, my car is possesed.... when i get the money i wanna get a plate reading cursd13 or Kursd13.... lol itsa known through uti as christine

biohazard

ill do those checks under the hood tonight maybe.... to see under my car i have to jack it up though so im alittle hesitant on that for the next few days....


cant exactly just look under it lol.... dont know how my jack gets under there its rlly rlly rly close

denniss

thats the same price I got from my boss. I am posting the GM imstructions to replace a radiator. Sorry there are no pictures, I haven't figure out how to post them with the text. Do you know if the AC condenser leaked? You would see oil around anywhere it leaked. If the AC system is still under pressure I would probably leave it alone (unless it is so ugly you can't stand it). If you have to change the AC condenser be VERY careful, R134a under pressure is
dangerous.
Good luck,
Dennis

thanks so much, i will look at it monday, i just took 6 weeks off of school to get my car back and going and make some more money to pay for it.... im kinda confused on alot of this, if you eventually figure out the pictures please post, or link to this ...eather way thanks so much for helping....if the ac condensor is fukd i will take it somewhere but i can figure the radiator out i mean its just R&R once again thanks

denniss

Hey Biohazard, if you take this on yourself and run into problems and you would like some help I have to work next Saturday, but I could stop by after noon and help you (if it isn't raining or snowing). You live a little far from me to come during the week. I have changed a couple Cobalt radiator/condensers. Just throwing an option at you. If your interested, either post or PM me and we can figure it out.
Dennis

biohazard

ill deffinatly keep it in mind, what sux though is i work fri sat and sun.... all day

biohazard

looked under my car today and i think it is just the radiator.... will remove the bumper to find more info tomorrow and test ac tomorrow

That Cobalt LT Guy

Heres one no wons said could it be your trans cooler how big is the part you dammged if its like a small radiator then that could be your trans cooler. Just some more info

biohazard

no no its one of the bigger ones.... ac condensor or radiator, and my resivoir is bone dry.... its the radiator

denniss

The trans cooler is in the radiator. I think your biggest headache will be removing the trans lines. If you read the instructions, you will be removing some splash shields. You remove them so you can get to the lower line. Also, I don't know if it is clear in the instructions but the radiator is comeing out from the bottom. You will have to be brave and jack it up high enough to get it out! If you have the bumper cover off it might come out from the top though. No special tools are needed, use priers on the hose clamps. When you refill, leave the upper hose off and fill it through the overflow tank. When fluid comes out put the hose on and finish filling. this will help eliminate air pockets. Check the fluid often for a few days just in case you get air in the sysrem.

how can i test to make sure its not my ac condensor? without filling my collent back up ( i dont have any) somone said something about the a/c clutch, like if it engauges its fine?
