Slant 6 Water Pump Core

It was a new pump from O'reilly. I warranted it out already back in November of last year and the new one didn't make it a year. But yeah, pretty much all parts store stuff is crappy now. I want a Flowkooler, but they're not available till December......if then.
I had a NAPA lifetime warranty pump replaced in 2009 and 2015 in a 73 Chevy pick up with a 250 6 cylinder. Just got that one replaced with a new (limited) lifetime
warranty, 3 years or 30K miles. New Chinesium unit. Painted it and then had to grind the housing because the back of the pully was hitting it. Long for the days
of American made auto parts.
