Hello, Yet another 2010 SS that just started to smell of coolant when the heat is on. Using the heater is a rare event in Louisiana so I don't know how long it's been happening. At 60,000 miles, my carpet is still dry. Not looking forward to the dealer visit. There must be a way to just bypass the heater core for now. Thanks for all the posts. I've learned a lot.

you could disconnect the hoses that lead to the water pump and block them off or disconnect from the heater core and put a u fitting to keep water circulating.

With all the heater core problems out there. Do you think they have a recall?

Why would they do that when they can wait for each individual failure & not absorb such a big hit all at once.
I wish they would . The thought of this failure in the future on my dime haunts me also.

Looks like my heater core is bad as well.:(

About 3 weeks ago i drove my car to work ( not my DD ), so driving home, i turn off on my exit and the dash lights up with "a/c is turning off" "Overheating" and my temp gauge is moving quickly to the right. So i pull into a strip mall and turn the car off. I open the hood, and see this...

My a/c belt has come apart, so i let the car cool off for an hour so i can drive the rest of the way to the house ( 0.9 mile )
I get home and look over the belt real good and find this...

As the a/c belt was turning to shreds, to took a few chunks out of my drive belt.
Then my neighbor walks over, gets the story, then asks, "hey, what's that?"

I check my coolant level, fine.
I check my intercooler level, fine.
So i jack up the car to find coolant leaking off the trans...

So i think about it and figure i have a hose clamp loose at the back of the intercooler (under the blower ) and it's dripping down the bell housing to the lowest point on the trans.

See those two brass fittings in the very back? That's where the intercooler hoses go, so i figured i was gonna be pulling my blower off.

But first i wanted to fix the belts.

So i install my new a/c belt, and my new drive belt.
Test drive the car around the neighborhood , no problem.
Car sits for a week.
I call my tuner John Lee at Atlanta Performance and Fabrication and ask him if i can pull the blower and replace the rubber lines with some nice SS lines with -AN fittings, he says sure, drive by next week and we'll look at it.
So yesterday i drive the car to my Dentist, within four minutes of leaving, my car starts to overheat again and i start getting coolant "misting" from the pass side vents, and drops of coolant on the pass floorboard.
So i let the car cool off for an hour, then drive to John's shop.
He puts pressure on the radiator system, and gets the car up on the lift, sure enough, coolant is leaking from right above the bell housing. He take the glove box out, and you can see the heater core, with coolant stains everywhere.

So John cuts a short hose, pulls the heater core lines off the water pump, loops the short hose, air vacs the system, adds coolant, and fires the car up.
So now i've got to call the dealer and talk about warranty work on the heater core. This should be fun.
Since they have to pull my dash and windshield, maybe now is a good time to upgrade to HUD....

Sorry for the long rant....
oh yeah, John also figured out my drive belt was a touch too long, so the belt number should be
1055k6 for a stock 4" pulley.

The heater core in my 2010 RS also went bad just this week. The first thing that tipped me off was the windshield fogging up, then drips of hot liquid from under the glove box, then a small puddle of red liquid on the garage floor. They told me same thing about removing/replacing the windshield. I just went over 10,000 miles so this is obviously a manufacturer defect. So far Henderson Chevy has been treating me well saying that it could take 2 weeks to get her back. At least they put me in an Equinox during the wait.

Does anyone know if this is an issue with 2012s? I heard about this about 2 days after buying my car and its made me a little hesitant to do any mods that may void the warranty (tune etc.) The labor costs of this out of warranty would be in the thousands.

I can tell you that my dealership started to give me a hassle about the warranty because of the headers on my car. I said its fine and i'd take it to another local dealership and immediately they said it wasn't a problem they'd fix it. I have headers, cat back, and a tune. In the end after discussing it with the service manager he said that GM would not cover any issues associated with the tune or headers (obviously) but all other parts of the warranty would be valid.

Hello DarkFox, unfortunately I haven't heard of this happening to a 2012 model Camaro so I wouldn't know personally. I'll try to keep my ear to the ground on this one and keep you posted. Have good day!

My 2012 has been at the dealer for one week today for bad heater core. I started smelling coolant then some hot coolant dripped on my wife's foot while driving so in to the dealer I went. Windshield is out and heater core goes in today or tomorrow. Until then I'm driving a 2013 silverado lt while on vacation. I'll follow up when I get it back.
From my cold dead hands......

My camaro started leaking coolant in the passanger side as well(inside). I also found coolant on my garage floor. Then today I tried to see where the leak was coming from and could not find a leak from inside or outside my car....I could however smell it if my heater was on. Is this normal? I would assume that if the heater core is busted, then it should leak whenever the car is on or has been driven.

Add another 2010 to the list!!!!

We got the burning anti-freeze smell when we switched over to heat. We dropped it off at the dealer Sunday night and they confirmed it was the heater core, and would take a week to fix. What a nightmare!

We bought our car used about 6 months ago and got the extended warranty through CarMax. They are paying for the part, the repair, the removal and installation of the windshield, but NOT the cost of a new windshield!

According to the Chevy dealer, there is a gasket seal needed to install the windshield and you can't buy that separate!!! You have to buy a new windshield with the seal gasket.

Hubby called and tried to find out why we had to pay for the windshield, when it needed to be removed to replace the part that IS covered by warranty. Best he could do, was get them to split the cost in half with us.

I posted in the Air Conditioning Issues thread about what is going on with mine. Blown evaporator core on my 2012 SS...

So far it has been a nightmare with the dealer I took it to damaging parts and pieces, delay after delay, I am just now requesting a rental but they have had my car about 9 days now and previously had it for 2 the week before diagnosing the problem.

Thumbs down Add another

I'll add my lfx to the list, with 15k miles though. I think it's asinine to have this problem. Just saying.
It's Just Dave
