Engine Failed

That's interesting it was in there for 5 years you say. Still looks like coolant not the coagulated and judging by the clarity it isn't filled with broken down parts of your engine.

Weird... It should be completely waxy sludge by now. How is your motor even running anymore?? [emoji23]

It's almost like dex kill isn't killing these motors. But I thought everything on the internet was true

Are you confusing the older blend of dexcool? The current (red) is 100k rated and turns pink when it begins to get contaminated. I haven't witnessed this waxy motor killer effect you speak of in any of these modern ecotec.

I would look at the water pump, not the coolant. They're covered to 100k with a special condition from GM for a reason

I am referring to the orange version. It is still sold at most places that sell coolant. If you go to Walmart, O'Reilly's, Autozone, or just about any other such place you will get the orange version. I have not seen the red stuff for sale anywhere other than a GM parts department.

I just finished flushing out my cooling system, and refilled it with Prestone OAT formula. This is NOT the original Prestone with silicates, it uses the same organic acid technology as Dexcool, and will work fine in any new or late model GM car. It meets GM warranty requirements. I plan to change it every 24,000 miles or 2 years.

Where did the 100,000 warranty come from and what does it cover? Mine says 5 years or 60,000 miles powertrain warranty.

The 14 is the last year to 100k powertrain, special coverage for water pumps on turbo cars goes beyond powertrain...

I don't have any concrete evidence either way but from experience working at the dealer we have allot of older high mileage vehicles we service with no coolant system issues. I am a ford guy but every gm I have owned has had dex cool in it, because I believe in factory spec fluids. The only car I have ever owned with cooling system issues is my sonic that just blew up because of a coolant outlet failure. But that has never had the same coolant in it for more than 20k miles. Because every time I turn around I'm replacing a mother component in the cooling system. So far I have replaced the coolant surge tank, most of the hoses, water pump, coolant outlet t-stat housing and head gasket. I wouldn't blame dex cool I blame the poor materials used to build the 1.4 and 1.8 liters. The 3.6 no cooling issues, 2.4 no cooling issues, 5.3, 6.0, 2.5, 2.0t. You guessed no cooling system issues. If any o e has some evidence either way, because on top of not actually seeing any evidence myself, I also know the original background behind the stigma. Including the lawsuit that GM lost in the 90 when they stopped calling it lifetime coolant

So many cooling and seals issues on ours too. Plus overflow tank cracked. Aftermarket $40 replacement feels tons better. But like you can’t say we have ever gone more than 20k on a tank of coolant bc of leaks etc

My 2012 Sonic LTZ turbo died as well a few days ago at 66,000 miles without warning. I kept up on all the routine oil changes and check ups. I called the dealer I bought it from and they said there's nothing they can really do, it's past the warranty. I was talking to the head mechanic getting prices to fix it (which I will never be able to afford) he had mentioned that my model had a water pump recall a few years ago. He told me that if the water pump failed then the engine would probably fail do to overheating. So I checked it, I never noticed any leaking before but it does have some corrosion under the water pump. My question is if it was the recalled water pump that failed and killed the engine does GM have the responsibility to fix the whole engine? I called the local dealer where I'm at but they don't seem to excited to get back to me on it.

it does look like the water pump seized up causing the engine to die but it doesn't look like GM will help me out much with getting the whole engine fixed so I guess I'm stuck with a dead car.
