2016 CX-9 Radiator Leak

[morenar]

Our 2016 CX-9 GT which is at 155,000 miles sprung a radiator leak. My first thought was the cracked block issue. Took it to the dealer and it looks like it was the radiator was leaking at the seams at the top. They were able to replace the radiator and no longer leaking. With a 155,000 miles, the radiator seem to have lasted a long time.

Anyone ever had to replace the radiator?

There was a TSB for a plugged heater core on some 2016-2019 CX-9s, but nothing specifically for the radiator. It's good to hear that it lasted you a long time

It's probably the same radiator that's in the CX-5 Turbos so it's good to hear it lasted that long.

Is it part plastic, part aluminum?

I think it's plastic and part aluminum. The area that was leaking was at the seams right next to the radiator cap.
