It's a radiator
It works, make sure you seal and tighten the trans cooler lines ,as they are loose and will leak

Excellent replacement ‘01 LeSabre
Fit 2001Buick LeSabre perfectly. Be sure and tighten fittings (check as were not tight from merchant, not judging’ just sayin’), we initially missed that. We replaced hoses and thermostat also.

Exactly replacement but fittings were not tight
I could of easily given this a 5 star review except the brass fittings in the radiator for the trans lines were installed but not tight. They held pressure during the warm up sitting still but spewed transmission oil everywhere during the test drive. A suggestion, either warn us with a tag or simply don't install them. If they are installed they should be tight, I had to remove almost everything except the radiator to see the lower oil line. Huge mess in the driveway and about 2 hours diagnosing and fixing.
