2016 Malibu 1LT 1.5T/6-speed 6T40
They did release a redesigned charge air cooler but it didn't seem to fix the problem for those that experience it. I wouldnt pay for it as it is probably waste of money. Why the freeze up happens to some and not most no one knows.Been experiencing the same problems.
What I have done Is pulled off the CAC in February 2021 and again in February 2022 and both times approx 1 L of water came out of the cooler after defrosting.
Unfortunately It looking like it’s gonna freeze up every year in the winter.
I’m not sure if there’s a solution yet? But I’m hoping there will be some sort of upgrade or fix to these CAC
