Baby it's cold inside...

Baby it's cold inside....

That van!

2015 GM plugged up heater core...

Forget about warranty work in my town.

Took to brother in law.

Back flushed out the heater core but the radiator and probably engine block could get a flush, but we were worried about plugging up the radiator...

Will maybe have to contact dealership 2 hours away to consider warranty work.

This is the original Dex coolant

Try diluting your antifreeze with distilled water, or buy the premixed stuff. Less mineralization.

But it will still be a Chevy.

Sorry to hear this. We've had to flush our heater core 1-2x per year to keep heat in the truck. Cripes. Thanks GM, you dufuses.
