RadiatorNow did a nice job. Order correct, quick shipment, well packaged. As far as the CSF radiator purchased, it fit perfectly and looks exactly like the OEM radiator that my husband replaced on the Hummer H3 Alpha. The only problem with the new CSF radiator is that it seems like the threads on the filler neck are not cut perfectly. Husband had two radiator caps, the old original radiator cap and a new one. Both of these fit on the old radiator without any problem. But on the new CSF radiator he said the new cap would not go on properly and would have cross-threaded the neck threads if forced. The old cap was very tight but went on without cross-theading anything. He just may need a pipe wrench to ever get the cap off.
