6000 miles. I replaced the OEM radiator in my CTS-V prematurely about 9 months ago, it was damp at the seams along the top and they have a reputation for failing prematurely. It did not fit my definition of leaking but I do very long trips on short notice so I figured I would change it and keep the old one around. Today the new one started leaking along the press fit metal to plastic seam. It as a tiny amount, but enough leaked out that it ran down onto the fan and some antifreeze was thrown onto my engine cover/headers. I noticed the smell when I got out of the car.
I bought it from Rockauto, they can be a little difficult about returns. Spectra Premium radiators have a 2 year warranty so I will contact the manufacturer first. I have my receipt and some of the paperwork from in the box. I'm hoping they don't make a warranty claim complicated. I installed it myself, a very easy job, the car hasn't been in any type of accident or had anything happen that would cause a premature failure.
