GENUINE GM PART
I found this to be a Genuine GM part which was more expensive than from my brother who works at a GM dealer and he was getting an employee discount.

OEM
Fit great in my 05 Buick Lacrosse Cx. Stick with the OEM brand even if it cost a little more. I also suggest you have the radiator flushed before installing. No point in clogging it if you haven't done a flush recently.
