vehicle age is just as critical as the mileage, have you ever done a coolant flush or atleast a drain and refill? Dexcool only has a lifespan of 5yrs after that it starts breaking down and can cause electrolysis or in some systems become acidic which can definitely cause a heater core leak. Recalls have very little to do with complaints they are normally only for safety issues or potential safety issues that GM has become aware of.

 

I have done 2 coolant flushes. I guess its just something to look forward when dealing with Dexcool antifreeze but thank u so much for the information. Greatly appreciated.

 

its all coolants not just dexcool

 

My girlfriend has a 2006 Chevy Equinox and the heater core has gone out. I am out of town and can't fix it and she needs to get it fixed. Someone tell me that there is recall on this product please. Thank You

 

There is no recall or special coverage campaign for the heater core. How was it confirmed that the heater core is bad?
